As I said, I think 51 would be about max. Once I hit 3200fps I'd stop and not be skeered to drop it a grain.
I know we've run 51-52 with the XLC, it was a Barnes listed load in an older manual. TSX and XLC tend to be kinda close in my experience.
Just checked and they showed 48.5 of H4350 with the 100gr X, which tends to be more sticky a bullet and I'd expect to get a few more grains in.
Load to velocity is how I'd roll and be content to stop at 3200. What's it doing at 50?
Brilliant. Check velocity at a pre determined speed and forget pressure. Just bloody brilliant.
Based on MAX's/pressure tested data between the std. 257 and the std. 25/06 with like barrel lengths using H4350, checking the speed IS checking the pressure.
Of course having the cases and primers not showing any flags, 3,200 IS about it.
Personally, I'd knock it back a grain too......
