I am not talking about changes oal from seating bullets when loading. I am talking about jamming bullets into the case to find the lands, then back off the bullets to find the most optimal seating depth for accuracy when developing loads.
Hi
I just have setback and recut my Tikka 223, 8 twist, barrel and made it into a 223 Ackley Improved.
Minimal load development so far, but it shows great promise, getting 1.5 inch groups w/ 5 at 200 yards with a couple of flyers.
Shooting 25 grains of Varget and 75 Hornady ELDM, New Lapua...
Tikka T3X stock
New in box Boyds at one stock with pillars - $280 Shipped.
Bought this for my son but got the wrong color. He already has one on a Tikka 6 CM and it shoots one hole groups.
