I've had a few over the years. All were set up to run the 75gr Amax. Standard load was 48gr Rel 25 and a Fed 210. 3500fps at 4500'asl. All were 8 twist barrels. Mine were all standard 22-243 Winchesters. Dies were readily available from Redding. No fire forming is needed. Simply run 243 brass through your sizing die. The most rounds I've had through one is about 800 and was still getting .5 moa. Recently got away from the .224 and started running the .243 105 amax. They seem to handle the Wyoming wind a little better.
