Identical Ammunition in Different Guns 

Me: I should go to bed. Paul Harrell: Permission Denied

I like how he clearly identifies the question first, then thoroughly answers it.

This might just be one of the most informative channels out there

I swear it never cease to amaze me when you just pulls out weapons out of the blue… I know there’s a Sherman tank somewhere in there…

Paul actually doesn't use a shooting chronograph. He just hears the shot and knows its exact FPS !!! 🤣

Paul's Wife: "why do you need 2 of the same gun Paul, it's getting ridiculous?" Paul: *points to this video*

Is that a beretta 92 self loading semiautomatic pistol loaded with green and white box 115grain round nose in your pocket... or are you just pleased to see me?

I'm sad for all the Meat Targets that did not find a forever home in this episode.

Actual conversation: Wife: "What are you watching?" Me: "RU-vid video about shooting." 1 minute silence. Wife: "He needs a new coat. That one is all frayed and the seam is coming undone in the back. Probably because he sits on it." I laughed so hard - I would never have noticed that in a million years. It was the first thing she noticed - she could care less about guns and shooting.

It's an even better day when paul harrell uploads.

There might be a hurricane outside, but as long as I have power and Paul Harrell, I'm gonna be fine.

Who else was waiting to see if he pulled that other .22 rifle out of his coat pocket?

I think after watching all of Paul’s videos to date, I’ve been conditioned to automatically be happy when hearing the intro theme. Thanks for the great content as always!

The double-barreled shotgun results were similar to a politician speaking out of each side of his or her mouth.

What a nice bit of land to play in.

Paul, paul, paul.. You've been in the game long enough. You've also established a reputation for being one of the only gun guys (if not the only) who knows how to create a detailed, educated, non-biased video for either reviewing or comparing two or more variables (guns, ammunition, and the like). Now, why haven't we seen an in-depth .45 acp vs 9mm comparo? I'm sure everyone would love to see a Paul Harrel approach on this topic i.e. educated, non-biased, and most importantly, non-toxic way of creating content about the comparison! :) Give this a thumbs up if you agree so Paul can see this comment and hopefully consider it!

Great content Paul. This is the best informative gun channel on RU-vid.

I think there's more difference between two "identical rounds" than there is between two "identical firearms."

Aaaaand he never looked at the gun or speedloader when reloading. Caleb can't do that.

Fun Fact: The double-barreled shotgun velocities are the combination to Paul's enormous gun safe.

Fine firearms all! However, I really admire your pair of Remington Nylon 66’s. The Nylon ‘66 brings back great memories. It was truly a rifle way ahead of its time. My only bittersweet memory involving my personal Nylon ‘66 was in trading mine away years ago while a young Marine for partial payment toward a first generation Colt AR rifle. ‘Semper Fi’.

Paul Harrell: "And the gun I'm using is stamped on the barrel...Marteen Amanetti FUBAR Spain. I'm probably pronouncing that wrong."

I wish I could have Paul Harrell as my professor for all my classes. He manages to convey useful information in the most interesting manner possible.

Scientist finally confirmed the universe could begin with a big bang turns out it was Paul learning how to shoot for the first time

All I can say is: Thank you sir. Thanks for taking the time to educate me. Thank you for your service, and thanks for continuing to serve. I think its the other way around...Bill Shatner has Harrellesque pauses. Keep up the great work. -- the smitz

Great video, I can't wait to see the halloween special for this year. If its not too late, I remember you mentioning reading books about criminal profiling and statistics. I think that would make a great video. Anyway, thanks for this video!

"Fubar Spain" "I'm probably pronouncing that wrong"

So happy there's someone who likes investigating banal (yet interesting) topics like this.

Your patient, analytical and professional, you deserve more subscribers.

I just love the little supersonic crack of the .22. Yeah I'm a geek.

Ruger sells pairs of sequential revolvers for cowboy action shooting...but to get a pair simply by accident???????????? Truly a charmed man! Deservedly so, great video as always!

Dam, i want a training facility!

That range has what we call in the UK "the zombie apocalypse bus." People in the US think of them as school buses, but we mainly see them with spikes on in zombie movies & games.

The answer is in the difference in metallurgy. Tool steel creates more drag on the projectile than stainless. The chrome mixture in stainless makes for a slicker barrel when compared to the high carbon tool steel. Another variable is tool fatigue. Hammer forged barrels are made on a mandrel. At the end of the life of the mandrel. The rifling, and barrel can be less desirable. A more accurate barrel is made at the beginning of the life of the mandrel. The better definition of rifling allows for the shooter to break in the rifle barrel into a sweet spot where the rifling, and round meet perfectly for better accuracy, or in the case of precision shooting. Where the barrel, and ammunition allows for consistent pressures leading to consistent accuracy.

Great video. Thanks Paul !

I just finished watching several videos back to back, just to find one more new upload "15 minutes ago". Thank you, sir!

Paul's videos are always worth the watch if you actually care about interesting facts and questions he's trying to bring clarity to. I can see this having a follow up video breaking down and explaining WHY there can be a difference between different firearms from different manufacturers that are similar in spec but achieving different velocities. In the case of revolvers, I suspect it has a lot to do with the cylinder gap and cylinder length possibly.

Ah, Nylon 66. First gun I ever fired, given to me by my father, and still hangs up in my bedroom. Such a nostalgic report too.

Hey Paul! Just wanted to say hi and thanks for all the work you've put in to this channel and community throughout all these years. Hope to see you into the future.

Thank you for another fascinating video exploring a topic of keen interest to us “gun minded” individuals. Paul and his friends have a fantastic collection of firearms.

So, I watched this video when it came out in October of 2020, and it popped up in my feed again in April of 2021. Paul has me so well conditioned, that even though I remembered it, I still clicked on it and watched it to the end. Thanks, Paul! It appears your training of us is highly successful. Your video shows up, we click and watch. Where that video is in the list of your videos makes no significant difference at all.

2:29 Before you fire a shot... The answer, in my experience is "Yes, but..." In my collection I have 3 S&W J frame revolvers, all with 1-7/8" barrel, a Model 40, a Model 640 and a Model 642. I also had (now passed on to two sons) two identical Ruger Model 77 RSI rifles in .243 both with 18.5" barrels and I have two Kimber Ultra .45s an Ultra Carry II and an Ultra CDP II, both with 3" barrels. I have 2 identical Colt Officer's Model Match Revolvers both with 6" barrels. I also have 4 .357 revolvers with 4" barrels but they are different makes or models. I have several O/U shotguns but have never tried the chrono test with them, or, for that matter any of my other shotguns. In ALL of them, identical ammunition fired over my PACT Model 1 Chronograph result in different velocity averages...and in the case of the Ruger rifles, one of them shoots consistently "faster" with any load I have tried through them. BUT...the velocity averages, while different, almost always fall within the "extreme spread" of the two guns. Meaning that individual shots from the same gun can, and do, result in variances as great, or greater, than the average difference between two different guns. So...YES, but the difference is negligible, IMO. Back to the video...your J frames had an average velocity difference of 46 fps but extreme spreads of 96 and 84 fps respectively. Your tests with the other guns confirmed that. So your results were consistent with what I have found. Different...BUT negligible.

Closed captioning between shotgun barrels being fired by Paul stated that the echo from the first shot was applause. So fitting.

This man never looked down for any of his reloads. :) Thats someone who has done this a time or two. Keep up the great work paul

Love how you get the revolver reloaded not looking at it. I also know you preach this type of operation during practice sessions. Great!

Been wondering about this video idea for a while now. Great timing Paul!

Still one of my favorite channels! Thanks for your work Mr. Harrell!

Not gonna lie, seeing those Vaqueros being unholstered made me smile for no real reason other than aesthetics.

as always, an excellent, well thought out and presented video

Paul Harrel never actually has to pull the trigger of a gun. He just looked at the bullets and quietly says”RUN!”

Here I am in January 2024 watching the Subscribed count passing 998k on its way to a Million. A testament to a worthy man who has entertained and educated us or years. Thank you sir!

What we learn from this man is priceless.

Slow barrel vs .Fast barrel. Drives handloaders crazy .I have heard accounts of 2.5 BBl having velocities greater than 4 BBl. with the same ammunition. Great video as always.

I know you like costumes. What about a poncho, wow brimmed sombrero, and a thick black mustache when you shoot the vaqueroes at the same time?

Good to see the local school system sends the kids to Paul's test for a field trip.

Once again Paul brings us to school - " HEY " he even brought the bus ! The dislikes must be from the ones that didn't see the right length bus for them and FEEL left out .

Thanks for making the Identical Ammunition in Different Guns video.

Would love to see this done with Glocks and 1911's.

nice blue sky... a great backdrop & location

FUBAR Spain is such a beautiful place this time of year.

Why Paul does not get more views, is beyond me.Almost the only man giving factual presentations without the BS

Paul needs all the space inside the school bus when he empties the guns and ammo from his coat pockets.

Having sequential vicaros is pretty cool. The only thing he was missing was the outfit, possibly a hat and blanket poncho

Thank you for showing the S&W Model 36, my favorite gun

Just when you thought there are no more questions or mysteries in the universe that Paul can't answer for us...thanks again Paul!

No matter how bad it is in the world all that just melts away when Paul harrell uploads a video

I've had firearms of the same model and configuration shoot completely differently. This especially true when pattering shotguns for turkeys with different ammo and choke tubes. I've also noticed a difference in older firearms vs newer ones of the same model caliber/gauge. Of course this is affected by barrel life and manufacturing processes over the years. It would not surprise me if two firearms directly off the assembly line with one different digit in serial number would shoot differently to some minor degree. This goes back to the age old rule of knowing your shooting habits and knowing your firearms "pull." Surprisingly, I do have a colt snubby and s&w snubby that do practically shoot identically at least in my hands. Go figure.

What an incredibly informative video. Paul is setting the bar for academic intellectual gun acquirement and velocity testing across all spectrum.

So distracted by the intro. Paul isn’t being attacked by the weather; either rain or snow.

Jerry Mikulek had a video on this topic a while back. His sponsor gave him 2 identical revolvers, both had different muzzle velocities caused by bore diameters within the tolerance limits but on opposite ends of the tolerance limit - ie: one at the lowest acceptable bore diameter and the other at the highest acceptable bore diameter. It was a significant difference in velocity. I will try to go find the video and link to it in an edit to this post asap.

I was hoping to hear that Remington's ammunition division had been purchased by Paul Harrell. Oh well....

Comparisons made here that few would think to make or have the equipment to make... Thanks, Paul, very interesting!

posted 4 minutes ago and its 17 minutes long and already a down vote... well we know who it is at least and hes prolly trying to look cool with a revolver.

I really liked the comparison of so many firearms to test and answer the question.

"It's not enough difference to make a difference." Paul Harrell quote of 2020 to save us from violent political chaos. Don't let this year's madness rip us apart. War is hell

Very interesting results. Thanks for the video Paul

"The longer the barrel, the better performance you get." - Paul Harrel Case closed, Paul has put the eternal question to rest!

Gotta love a statistics lesson along with gun knowledge...always informative and entertaining.

honestly youre doing better small arms research than most countries

That man pulled a magician trick at 3:02

Paul on a friday night video... worth many dollars... Paul answering questions i didnt even know needed to be answered.. Priceless.... Thanks again Paul.

You make pockets look good, Sir.

Nothing is quite as satisfying as pulling the the bolt handle back on a Nylon 66 and watching that first round leap into the chamber.

My theory is tolerances in the gun, if one gun has a better gas seal then the other it could build more pressure to propel the round at a higher velocity and variances in the rounds themselves due to primer burn and power burn. But as always, you be the judge.

I remember in 1980 we used the Remington nylon 66 .22 in hunter safety class...shooting in the rifle range of a basement of an elementary school. Good luck finding a rifle range in an elementary school in 2021!

Field trips have gotten more sophisticated since I was a kid.

My wife said, “he’s just standing there talking”, and I said, “exactly, and I’m just sitting here listening.” Always learning something new!

BZ. The only thing missing is the data tabulation on the cardboard easel.

Paul’s reloading skills are excellent. Head and eyes up at all times. Looking down range not at the firearm. Just like riding a motorcycle. Head and eyes up at all times. Looking down the road, not down at where you are.

For the revolvers I'd be interested to know the gap between the cylinder and barrel on the respective guns. You could use an automotive feeler gauge.

Paul put his old jacket on for this one....he means business today

Paul's field jacket is older than some of his commentors.

I love the smell of gunpowder, in the morning.

With all the trashy crap on RU-vid and all over the news right now, I need some calming, relaxing educational content. So here I am.

One of the most interesting and also surprising videos yet ,Who would have thought that Two different manufacturers seemingly similar weapons would make the differences observed , probably more critical in smaller calibres when any loss of velocity and thus energy is even more significant and may even be critical . Thanks Paul , Shoot Straight Stay Safe & Stay Well .

This guy can't be any good. I don't see a giant beard, a trucker hat, tattoo sleeves, or roid rage. ;)

After watching a lot of your videos and hearing you discuss this topic a lot it took me a while to watch this. Such small differences can come from a multitude of different things. As always though, we can rely on you to put it to the test.

Given that the firearms tested are revolvers, is it possible that differences in the amount of cylinder gap provided varying pressures from the same ammunition, giving different velocities?

That was a great video. I just enjoyed you shooting various models and calibers. Thank you for this presentation.
