My new swift should be done in a week or so and I'm getting ready to start ringing her out. Looking for ideas where to go for speed and of course accuracy. It's a 1/14 twist, 24 inch varmint barrel so I'm probably going to shoot 50gr and under bullets for now, although I'm probably going to give the 52gr Bergers a try as well (love Bergers for Coyotes). Powder on hand are RL17, I4198, H4895, I4350, I4831, H335, H322, and Varget.
My long term Swift load was WW brass, Federal 210M primers, 50 grain moly coated ballistic tips, and 43.5 grains of H380.
I had another for a short time that perked up to 44 grains of IMR 4831 and 55 grain ballistic tips. I could not get 44 grains in new brass, had to fire-form first.
I used the starting load of 4064 under Speer 52 grain bucket mouth hollow point seated out / jammed into the rifling. Accuracy was pretty spectacular but it was slow.
