I shot Ga state match around 70deg on my limcat 6 wildcat KKM barrel. i put 5.1gr of N320 behind 180gr FMJ Montana Gold, mixed brass, 1.195 OAL, Winchster rifle primer and my PF that day is 170.5. A month later i shoot NC in a chilly 50deg. I barely made PF at 165.5. I think i have a slow barrel. This winter i will bump my load Vihta Vouri N320 load to 5.2gr. I think 5.2gr is my sweet spot. I need to develop an alternate load for titegroup though since VVN320 is sometimes hard to find and getting really expensive.
