Any body have a Sig cross they loaded for yet? 16'' 308 and or 20'' barrel? Thanks
My 308 Ruger M77 mk ii has a 22" barrel and loves 165 gr Sierra GK with 40gr of IMR 4895 at 2.750 oal. The sig cross with 16" barrel, not so much. Hoping to find data specific to the cross.The .308 is probably the most commonly shot cartridge. It's going to be either varget, n550, imr 4064. If using varget it's going to land between 41-45 grains with a 175 matchking. Load to mag length or .020 off.
Each chamber is cut differently, even chambers in the same make of gun are cut differently. You will never find a "rifle make" specific load data.My 308 Ruger M77 mk ii has a 22" barrel and loves 165 gr Sierra GK with 40gr of IMR 4895 at 2.750 oal.

Perfectly understood. Even the harmonics of each barrel vary. I'm just looking for some good starting points.Each chamber is cut differently, even chambers in the same make of gun are cut differently. You will never find a "rifle make" specific load data.
