Took my aac 77gr OTM out to 870 yards with my 16” aero precision complete rifle using a vortex gen pst gen 2 3-15 scope. The target was a 1 MOA steel target at 870 yards.
Thank you for the words of encouragement! Since this video, Now that I have a Chronograph, I plan on working up some handloads for this rifle, and revisiting some of these off the shelf loads.
I use IMI Razor Core normally. 77gr OTM. It's 1/3moa from a CZ527 24" barrel. It's 3/4 moa from a 24" Radical AR. That's no knock at all. The AAC 77gr is almost identical at .338" from the CZ
I bought the AAC 75gr OTM, AAC 75gr Saber, AAC 77gr SMK, and AAC 75gr TMK. Also have ~1500 rds of Hornady 75gr BTHP. Will be testing all this weekend out of a BA 18" barrel on a to compare accuracy. Hope at least some of the AAC lives up to the hype.
@benjaminfries8413 In order of accuracy, the AAC 77gr SMK's did the best, with a best group of just under 0.5 MOA. In order, best to worst: 1. AAC 77gr SMK 0.676" 2. AAC 77gr TMK 0.740" 3. Hornady Frontier 75gr: 0.934" 4. Hornady Black 75gr: 0.969" 5. AAC Black Tip 75gr: 1.272" 6. AAC OTM 75gr: 1.317" A note on the SMK's: I chronographed them at 2630 fps with a SD of 33. The Hornady Frontiers came in just under 2750 fps with a SD of 16. I didn't chrono the others.
@Fister_of_Muppets sounds like they did well. I’m going to revisit this again with my rifle with two things I’m going to do differently. 1) from a bench with good support 2) I recently got a chrono, and want to see what numbers they are doing from my rifle. I’ve learned a lot since this video, especially how handy a chrono is.
Hey brother I bought a snap cap dummy round to check my mechanics before I squeezed the trigger with a live round. I hand load my 300 win mag and i've gotten half inch groups consistently.
A tad disappointing, but hey you’re learning a lot about the technique and what works. I think those 2 thoughts regarding using a smaller point of aim, I recommend a grid style target with squares or diamonds…. Aim at the point of one of those. You can download and print them if you have a printer. Your other thought regarding fouling the barrel, that might also help. Some barrels do take some time to settle in. Typically when I shoot my rifles before hunting season, I don’t clean them for this very reason. Anyways, so cool to be involved in this journey with you! I might try and take my rifle with that barrel back to the range next time and see what I can do. I have some match ammo I can run through it. Hope you have a great weekend brother!
All this quibbling (not you specifically) over AAC ammo's performance. Anything under 3 moa from a 77gr will effectively put any bipedal pos in the dirt from any distance likely to be encountered in a 'civilian setting'. Could care less about group holes sizes on paper at this grain weight and price......
@@billydanzz I understand what your saying,but part of the fun I have with this rifle is two things 1) seeing what ammo meet’s Ballistics Advantage MOA guarantee, and 2) how tight a group I myself personally can do, as that’s part of the fun for me. I have no doubts I can carry this rifle out to 5-600y (which is a goal of mine personally, once I find a place nearby to do so) but I’d also like to see how tight I can stack them together, and 100y is all I have currently. I appreciate the comment, view, and general conversation!
I think it’s pretty cool I found u on Instagram getting lost by clicking @s on content I liked. Ended up looking at some a1 upper builds and then found myself here. I absolutely love the 77gr otms and what’s funny is we are using the same exact rail and barrel. I installed my barrel and rail onto my billet cross machine tool upper and mated it with cmt lower as well. Is there a break in period on these barrels?
They have a break in procedure on their website that’s as follows: “For Stainless Steel Barrels: -Start with 5-10 one-shot cycles: Fire a single round, then clean the barrel. -Proceed to 1 three-shot cycle: Fire three rounds in succession, then clean the barrel. -Finish with 1 five-shot cycle: Fire five rounds in succession, then clean the barrel.” I followed this procedure, but I also feel like the more rounds I send with it the tighter it should get also. As of now I have maybe 250ish rounds down on mine. Appreciate the follow!
To begin with you need to know what twist rate your barrel has if its a 1in9 twist you need a light weight bullet if its a 1in7 twist then you can use the 77 grain loads also the 5 round individual shots are done as follows - you put 1 round in the mag , insert the mag , hit bolt release , fire that round , drop the mag , load 1 round in the mag , insert the mag , fire that round , repeat , this opens the back of the barrel so air can go through for a few seconds while you load the next single round in the mag , you do that 5 times supposedly that will give you a better 5 round group than if you trap heat in the barrel shot after shot
I don’t know that it does in a semi auto. Ballistic Advantage measures the MOA guarantee by either 3 rounds fired from a magazine, or 5 rounds loaded by hand. That’s the reason for why I was doing it that way.
BA barrels are junk for precision. General purpose 55/62 grain stuff, they’re fine, but I have given up on them for any precision type build. You may squeak some sub-MOA 3 shot groups but they are not consistent and are picky when reloading for them. If you shoot 5 shot groups, they are 1.5-2.0 MOA barrels. Their sub-MOA guarantee is a joke.
Interesting feedback. This is the first feedback I’ve gotten from anyone really on them. I shot 5 handload the other day, 4 were within 1” and the fifth got it to 1.25” overall. It’s been the best I’ve gotten with it so far. What barrels have you had good experience with?
@@j_c_hunt white oak armament have always been consistent performers for me. Rainier arms select or match barrels are usually good too. Can’t go wrong with a compass lake engineering either, a bit more pricey but definitely worth it!
@@JGoodZX6R thanks for the advice. I may look at swapping thing barrel later on for one of those, and put this one on a “general purpose” rifle, if I can’t find a handload or anything it likes.
@@j_c_hunt good luck on the reloading. BA 18” SPR is what I had, I nearly gave up on reloading it was so frustrating. Would shoot a load well one day in testing, then the next it would be 1.5”. Part of why I mention their inconsistency, and i had the same experience with a 16” SPR fluted. Replaced the 18” with a WOA 18” SPR and it shot a large variety of the same loads much better. For some reason I didn’t learn my lesson and got a 18” SPR in 6mm ARC (great sale, so I got sucked in lol). Shooting only factory Hornady loads. I initially thought it liked 108 ELDM, but again, this barrel is inconsistent as well. Would literally stack 3 shots at 78 yards (furthest I can quickly get to check accuracy without going to a range), different lot number of ammo and it was 2-ish MOA. Same with 105 HPBT. Looked back at all my data and it was 1.0-1.2 MOA fairly consistently. So I thought maybe 105 was going to be what it liked…I’ll take 1.0-1.2 MOA all day IF it’s consistent. Ordered some more 105’s (different lot number) and every group (5x5 shot groups) is 1.7-2.0 MOA. Just going to “splurge” on a 2x the cost Compass Lake one. 6 ARC is too expensive to mess around with an inconsistent barrel.
@@JGoodZX6R so far I’ve got 24 grains of Varget with 75 grain hornady BTHP match to shoot the best. I’ve got some loaded with -.2 and +.2 grains to see if it makes a difference. Like you said, I picked this up because they had an awesome sale on them. It’s a nicely made barrel, just I haven’t got the accuracy I thought I would. I’ll look into a white oak or one of the other barrels you mentioned at some point if I can’t get anything more precise out of this one. For shooting coyotes, the accuracy I’m getting is plenty good for that.
