Thanks for all the tips folks. All brass was used and full length sized. Definitely could be pushed harder. I’m going to play with heavier bullet weights for now then go from there. Maybe some different powder as well (I have a few pounds of Tac I picked up cheap).
B23 it’s actually a Model 70 Varmint from the mid 70’s. Kind of an odd ball with lower production numbers from what I’m told. It’s pre xtr.
I’m happy with it. I’m not a slouch for a shot but wasn’t shooting with a rear bag. There’s improvement to be made. Just trying to decide where to go with it.
I’m doing a Varmint shoot at local range this Saturday and am trying to decide if I take a 6.5 Creedmoor or bring this instead for cool factor.
