I have recently acquired a bunch of N 140 and was curious if anyone has worked with it yet.
https://6mmarc.com/showthread.php?tid=124
It was mentioned here as being a preferred and optimal powder. While I had a great experience with the little bit of H4895 I had, I have zero experience with VV powders. All I know is people love them and they are $$$. Hornady has data on other stick powders that are generally similar to N 140 and has data for it with 108-110s. I don't shoot anything anymore other than 105s and smaller so I'm trying to extrapolate data from published stuff. VV has data on 6BR Norma but the 6 ARC is only ~86% of it's capacity among other differences I'm not aware of probably.
Would 25ish grains with a jump be a decent (safe) starting point perhaps? Or am I lowballing too much? I've run 26.5 to 27gr of H4895/105VLDs without problems but accuracy was at 26gr with minimal development...although a slow 2608 in a 24" Criterion barrel. My goal is 2750 at the very least for BC reasons, if I can get the speed with 95s they will match or better the 105s in wind. Any opinions and input is greatly appreciated.
