First outting with the G34 loaded with MG 124 fmj, WSF at 5.0, federal primers, mixed brass. OAL was about 1.130, using Lee 4-die set with crimper in the 4th station; OAL had slight variations in Dillon 550b. Nice shooting in terms of recoil and accuracy. Clean. Ejection was about 3 to 4 feet. Just made the switch from Berry's 124 rn copper plated, Accurate #2, cci and mixed brass at around 1.123. Question: is this what I should settle on this being my IDPA (I'm a newbie shooting local) or would 4.9 be better some way or going 5.1? I know I should make a batch and try but thought I'd ask just for general knowledge. Don't have a chrono and admittedly the shooter has more affect on overall target hits (dry firing regularly) than minute variations in reloads. Thanks in advance.
