    6.5 Creedmoor

    If you're not running heavier than 140's H4350 will serve you well. I've had very good luck with 41.0g of N555 with 153 ATIP's and 153.5 Berger LRHT running about 2640fps.

    6.5 Creedmoor

    41.0 N555 with 153 ATIPs. 5-8 SD and 15-18 ES.

    Anyone here using the Hornady A tip bullets? (.308)

    Don't have a .308 but the 153 .264 ATIPs have been the best bullet group wise and SD/ES wise in my 6.5CM.

    MPA Matrix Pro II

    I've had mine for about 6 months. Love it. Adjustable bag rider comes in very handy. Internal weight system is great and easy to install without removing the action. The fore-end is a little wide, if I could do it over again I'd go Vanquish.

    6.5 Creedmoor

    Copy that. COAL is 2.861 +/- .001

    6.5 Creedmoor

    Using the SAC comparator my CBTO was 2.080". I can push the 153's up to about 2700-2720 but start getting over pressure signs. I don't see a good reason to run that hot, dispersion/ES/SD's open up and your throat is getting blasted away.

    6.5 Creedmoor

    Update: Amazing results with N555 and 153 ATIPs. I only loaded 15 rounds, Peterson SRP brass, CCI BR4, 41.0 of N555 80 thou of jump. It was running 2625 avg with a 2.2 SD and 6.8 ES. Group was .551 MOA @ 100yds. I'll be loading more of this to verify.

    6.5 Creedmoor

    What I don't understand is VV lists load data for N555 and Berger 153.5 LRHT's but not 153 Atips? I would think they'd be identical loads.

    6.5 Creedmoor

    I'm using Peterson 6.5CM SRP brass, CCI BR-4, 41gr N555, CBTO 2.085 (80 thou off my lands w/ SAC comparator). It's getting me 2630fps out of my BAT Hammerhead with a 26" ACE barrel 1-7.5 twist.

    6.5 Creedmoor

    Does anyone have some load development for 153 A-tip using N555? Curious what charge weight and seating depth you are using. Vihtavouri doest list N555 load data for this bullet and I can't find it in any manual. Is it not a reccommended combo? N555 is getting me some good results using Berger...
