I'm going to attempt loading for a friend that taught me the basics and is having trouble with a 257 WM. It's a cooper rifle, 1/10 twist pretty certain a 26 inch barrel with brake, Timney trigger.( no idea on the brake) Maybe 100-200 rds through it. He really wants to shoot Barnes TSX 100gn.
I've read some on here where some like to seat these bullets deeper, keeping an eye on the grooves. I'm good with trying that and also various powders. I'm looking for proven powder choices here. I think I'm interested in RL 22 and 25.
I'm looking for any info that might help me along here. He had gotten rid of another 257 WM because he had trouble getting it to shoot well. So maybe there is something I'm missing here?
