Hodgdon have data

Looks like 44-45 grains would be a good place to start
Need to check the details but it look quite slow for an 85 gr in a 243.
This is with a 20" barrel, 24" shows 3130 fps.
Yet when you look at Hodgdon's site they have staball 6.5 driving a solid copper bullet at 3400.
GRT shows a max of 3120 fps at 45 gr with the barns TSX while Hodgdon gets up to 45.6
Guess that why it's important to consult a number of sources for your data and then work up slowly

Being a solid copper, the barnes may increase pressure and therefore velocity.
I have a barrel from a blown up rifle from that sort of thing happening
Barnes generally won't because of the relief grooves in the shank of the projectile,Quote:
