Re: 243 win and Hogdon H100V
Just for the heck of it I did some 243 chrono testing. H superformance and other powders. IMO H superformance could work in 26 inch or longer barrel with 100's and 107 gr. The best seems to be Hybred 100 V and just settle in on 3200 fps
My rifle is a 26 inch rem 700 9 1/4 twist
Hodgdon superformance powder
I only had 100 gr spbt's It could have been loaded higher, but the case was nearly full
46.5 gr 3148 with a dev of only plus or minus of 12 fps for 5 shots 85 degrees 4600 feet elevation. chrono 20 feet from the barrel
