I have a new rifle that is 100 fps slower than book max loads but at the book max powder volume. Has anyone else ever had this issue. I am assuming pressure = velocity. If that is so, then it seems safe to go slightly above "book max" in this rifle to reach top end velocity?? What say you?
And what is the reason that book loads are as much as 150 fps slower in this rifle? I have double checked my pro Chrono and this is consistent across a number of different powders. I know some manuals use a 24" barrel vs my 22" but the discrepancy still seems way off. Looking for everybody else's "2 cents". Thanks, John.
How many powders have you tried? 1 powder isn't enough to just state that you have a slow barrel. More than likely, it's the powder itself that isn't delivering the speed your after.
