Re: Accurate and hard hitting
You can try the 50-vmax's with :
Hodgdon H335 @ 25.0 grn. -or- Vihtaviori N-133 @ 23.5 grn.
Neither loads are maxed-out on the Vel. so there is a ( little bit ) of upward Vel. to push . but see how it Groups with 3250 -3300 fps 1st before pushing it up
I shoot both loads from two 1 in 9-twist and one, 1 in 10-twist barrels. , 2 of the barrels are 24-inches long .
Your barrel is 1 in 12" twist but it is still going to be close in the handloading with 9 & 10 twist barrels shooting the 50 grn. bullets .
