Swiley383 Posted March 16, 2019 Share Posted March 16, 2019 Anybody use AR comp for 223 and 308win? Thinking of giving it a try just wondering how well it did and how well it meters. Link to comment Share on other sites More sharing options...
chevrofreak Posted March 16, 2019 Share Posted March 16, 2019 I love it in .308, but I don't get the velocities I want in .223/5.56 before I blow primers. I load a 150gr Barnes TTSX to 2900fps in a friend's .308 Savage rifle - 100fps faster than factory Barnes - with no pressure signs. Link to comment Share on other sites More sharing options...
Swiley383 Posted March 16, 2019 Author Share Posted March 16, 2019 What about with a heavy bullet my 308 likes 168 grain? So far I have only loaded 55 grain bullets in 223 but I have seen some good deals on 62 grain bullets. In 223 I have been using mostly CFE 223. I also like Win748 and H335. Just looking to expand my powder choices. Link to comment Share on other sites More sharing options...
chevrofreak Posted March 16, 2019 Share Posted March 16, 2019 His rifle also shot incredibly well with AR Comp and 175gr RDF bullets. I think I just threw some together at Alliants max charge of 41.4 for a 175 Sierra just to break the gun in and it was sub 3" at 300 yards.

chevrofreak Posted March 16, 2019 Share Posted March 16, 2019 (edited) Here are some of my .308 bullets arranged by weight to show how long the TTSX is. 150gr Hornady Interlock, 150gr Barnes TTSX, 168gr SMK, 168gr A-MAX, and 175gr RDF.

Swiley383 Posted March 17, 2019 Author Share Posted March 17, 2019 (edited) How well dose it meter? RL 15 seems to meter well thru my hornady progressive press. Edited March 17, 2019 by Swiley383 Link to comment Share on other sites More sharing options...

I have only used it through my Dillon 650 for doing .224/5.56 and it did OK. My velocities were pretty consistent despite mixed brass and being loaded on a progressive. I was loading the RMR 69GR 3GH with 22.5gr which was disappointingly popping primers in my Bergara .223 Wylde chamber, but not in any of my 5.56mm chambers. Max velocity: 2976fps Min velocity: 2916fps Avg velocity: 2950fps 34 shots That barrel will throw CBC 77gr SMK MK262 clone ammo at 2958fps average with no blown primers. Just dont expect top velocity with the AR Comp. It also produces less gas than many other powders. Shooting suppressed with my 24" Bergara barreled AR with a rifle length gas system using an Adams Arms piston system, I have to run it on the unsuppressed setting, but all other powders will run on the lower gas suppressed setting.

I've used AR-comp extensively in .308 & 223/556. It meters VERY well...almost as well as ball powders. It also produces outstanding accuracy & is very temperature stable...no change in POI in cold vs hot weather. Use the data on Alliant's website...those are actually the accuracy nodes per my testing across multiple ARs. You'll be pleased with it. Link to comment Share on other sites More sharing options...
