Let's say I have good data for a 240gr LSWC using Unique in the 44 magnum caliber, but I only have 210 grain cast RNFPs. Is it safe to use the data with the lighter bullet ? Will it generate more or less pressure than the 240 gr load does ?
This IS one of my questions whose answer I am in no doubt about, and I post it just to foster lively debate, and the recounting of experiences so that we all may benefit.
Notice I said "safe", not accurate, faster, more accurate...just safe.
