TPM - Intro to "The Precision Rifle Reloader" Series , Custom Rifle Build Overview + Bonus CONTEST! 

Thank you, I figured this would be a great topic. I plan on breaking every step down to the very finest point and explaining the "why," something I find very important when learning a new skill.

You are welcome. I will not disappoint. 😀

Awesome to hear! I hope this helps you get started on the right foot.

Your'e very welcome. Thank you for watching.

Oh I will 😀 My problem is going to be keeping the information well structured and concise. Either way, stand by for some obnoxiously detailed videos. This will be fun!

👍👍

I absolutely, 100% agree. Sample size allowing for a statistically significant probability distribution in terms of "precision" is absolutely necessary to evaluate performance. I've touched on this before, part of the problem we experience as precision rifle shooters are all the variables, both human and environmental, that play a significant role in how our rifle shoots. Then there is the statistically defined difference between "accuracy" and "precision." In a nutshell, accuracy measures where you shot, or the mean POI for a group of shots, lands in relation to the POA. On the other hand, precision measures your group size, CTC (center to center) for the two rounds that landed furthest from each other on the target. As we increase our sample size, i.e. the number of rounds fired into a group, the probability distribution, which is theoretically shaped like a bell curve, will give us a more "true" or significant representation of both accuracy and precision. The same is true when we attempt to find our mean velocity for a new reload. Firing 5 rounds isn't enough.... Ten is better.... 20 is even better. As I mentioned above, there are so many variables we must contend with on not just a daily basis, but a shot-to-shot basis. Some examples of "daily" variables include the environment / weather, the range we are shooting at, our physical and mental condition that day, just to name a few. Examples of "shot-to-shot" variables include all the mechanics involved with us, the shooters, pulling the trigger, the rifle's condition, once again weather, and so on, and so forth. I've tried hard to think of another sport that is as challenging to get true, raw, statistical data regarding performance. For true "testing" there are a few things we can control. We can bolt a rifle into a mechanical fixture to eliminate the shooter's input, we can use electronic or mechanical devices to release the firing pin, although unreasonable, we could check the case volume of every case we reload, check our case dimensions with a laser coordinate measuring machine, charge powder to the .000x grain, weigh bullets, check bearing surface dimensions, the temp of our rifle / ammo, etc. On the flip side, there are also several things we cannot control - weather and environmental factors, the burn rate consistency of the lot of power we use, the flame heat from the primers we choose to ignite the powder, the cumulative effect of throat erosion, land / groove changes from bullets traveling down the barrel. I wasn't a statistics major but I did take several undergraduate and graduate college courses on stats but unfortunately I've forgotten quite a but 🤦. This is the part of precision rifle shooting that can either interest you to the point of obsession, or make you go crazy thinking about it. Either way, great information, great post, and and great points. Keep this stuff coming boys! -Shawn

Howdy friend, my in-laws just got back form visiting you're country. Nothing but great things to say. Thanks for watching. -Shawn

It will be worth the wait. Thanks for watching.

There is A LOT of information to cover. It's gonna be a good one!

Why thank you sir! Very kind of you.

HAHA! That made me laugh. I guess you could consider me a 300 NM addict as well! I've built three so far, and I think I'm going to get the "improved" reamer sent out to play with. Supposed to do wonders for efficiency and velocity. There will definitely be a video on that canon. Thanks for watching! -Shawn

@@triggeredprecisionmachinellc You're welcome. Looking forward to it.

Absolutely! I separate that stuff into two areas - tuning the ammo and tuning the rifle. The ammo tuning gets handled first and if you aren't where you want to be accuracy wise, then we can either re-address some different things with the ammo, or make changes to our rifle. The tuner / tuner brakes are an awesome way to wrap up your tuning for maximum accuracy.

Sounds awesome, Todd. You are pretty darned knowledgable about the reloading stuff. If you come up with any nifty topics I can cover, shoot me an email. Thanks man! -Shawn

I've started typing up some of the dialogue and organizing topics.... WOW..... there is a lot to cover. Buckle up!

Thank you, sir!
