when working up loads, do you guys do your groups in 3 shot groups or 5?? im brand new to reloading and i just loaded up some rounds using retumbo. i loaded mine up in 5 shot batches. 2 batches shot awsome for 3 shots and blew the 2nd two way out? the two best 3 shot groups were right at .56 and another at .71 suggestions? what should i change? should i play with seating depth, and at what seating depth should i start at? the seating depth i chose was based on the instructions in the nosler book IF i even did it corectly and i believe my c.o.a.l was 3.372 but the load data i got from berger was for 3.40.
I would keep with 3 shots for a 264. It heats up the barrel pretty quickly, so I would shoot more groups of 3 shots, rather than trying to get 5 down the tube. It is burning alot of powder behind a small bullet.
