Background:
first things first looking for input to load up a "go to" load to work out as I am having accuracy issues, my attempts are to rule out variables (Me, ammo, rifle).
1. I established my seating depth with a dummy round by slowly decreasing C.O.A.L until round would feed with hand pressure and extract easily I then seated in another 0.010". Because somewhere I recall Sierria likes some jump and to reduce chamber pressure.
2. I chose AA2520 as the powder to use based on I have some on the bench and I hear many have good results.
3. Loaded up twenty of the 120 SMK, AA Brass virgin, WSR Primer, AA250@29.3grs, Coal Worked out to 2.230" (thereabouts as we all know that this will vary on this bullet). Loaded additional 20 same same except the charge is at 29.8grs.
Question are these loads in the ball park?
