Hi Guys, I want to start working up a load for my 6.5 Creedmoor AR-10 build. I’ve loaded for Creedmoor before, but not for a gasser. I plan on using Sierra 142 grain SMKs, Lapua brass, H4350 and CCI small rifle magnum primers. Unfortunately I can’t find solid data on that particular combination of components. Do I need to reduce my starting charge weight due to the magnum primers, or Lapua brass (I’ve read that it has less capacity then others)? Do I need to modify my starting charge because I will be using small rifle primers instead of large? Is anyone willing to share pet load data for a gasser with similar components?
The rifle is a built on an Aero M5 enhanced receiver with Aero high pressure BCG and a Bartlein 22” Barrel with +2 gas and an adjustable gas block.
Thanks for any info.
ETA: I know it is usually advisable to down load a gasser compared to a bolt, provided I stay under max should I be OK or should I consider max a grain lower for a gasser?
