Went to the range today with some loads of Norma 200 and some loads that were Acc 36-180 YG and Acc 35-125 YG.
Turns out a FULL case (slightly compressed) made those boolits go THE SAME VELOCITY...
So the 180s are about 2000 fps with 28 grain and the 125s are a little plus 2000 with 29.5 grain. But 29.5 grain filled the case up to about 1/8" from the top of the case!
However, it looks like with Alliant 2400 (according to QuickLoads), I should be able to send those 125 around 2500 fps... Will have to try it next week.
