[QUOTE="AudentesFortunaJuvat, post: 1990617, member: 115510"] I’d check out RL-16 or RL-26, both good powders that gave me best velocity in my 6.5 creedmoor, 2720FPS out of a 22” proof sendero with 42.2 grains RL-16 seated .090 off. Unfortunately both are hard to find right now. I’m seeing RL-26 push 180gr VLD from a 7SAUM at about 3030fps. Sort of sounds like a different issue, something other than powder choice. I’m concerned that your guessing how far off the lands you are. If you are in fact seating to be into the lands, that could be your pressure, maybe your setup wants to be jumped more/less. i would recommend getting the Hornady gauge or using the chambering method for determining your max CBTO so you have a defined measurement to work with. Then follow Berger’s seating depth testing process outlined on their website to determine your optimal seating With a safe charge. Work from there on the powder choice and charge. Stick with one bullet so bearing surface is constant and you aren’t affecting your charge or potentially crushing powder with the 156. just my .02, take it with a heap of salt as I’ve only been reloading my Creedmoor 2 years, still lots to learn.
