[QUOTE="thomasbangs, post: 1439139, member: 49922"] I have had very good luck with powder WC 844, this is a surplus military powder that is the equivalent of H 335. I have used this in service rifle competition out to 600 yds. with 24 grs. behind a 75 gr. Hornady 75 gr. HPBT Match seated out to single load only in a AR 15 with a 20" Bushmaster barrel and Jewell trigger. This load will hold the 9 and 10 ring at 600 from a sling shooting prone, it will also shoot moa at 100 yds. from the bench, for magazine function, I reduce load by 1 gr. to seat bullet deeper. You should not have a seating problem with a bolt gun. I also have a varmint AR with a 20" Shaw stainless bull barrel and a Timney trigger, this will shoot 5 different bullets under a inch at 100 yds. with this WC 844 powder with various loads (23 to 26 grs.) including the 24 gr. load behind the 75 gr. Hornady HPBT Match. My hunting load for this .223 is 23 gr. of WC 844 behind a 60 gr. Hornady V-Max, Win. small rifle primers, Win. military or LC brass, seated for magazine function it will consistently shoot under 1 inch from the bench with best 5 shot group measuring .556. I layed in lots of the WC 844 when it was available, if you can't find any of this, try a lb. of H 335, hope this helps. Just thought I would add, the service rifle with a Bushmaster barrel has a 1-9 twist, the Shaw barrel has a 1-8 twist, velocity out of the 1-9 twist 20' Bushmaster barrel with the Hornady 75 gr. HPBT in front of 24 grs. of WC 844 seated for single load only is 2826 fps with a ES of 35 fps. [/QUOTE]
