Thread: 260 and h414/w760

I would say you are in the ball park. I am using it in 6.5 Creedmoor, so a slightly smaller case. After a LOT of testing and working up slowly past the max published figures I am sitting at 42 .7 grns and also using magnum primers.
Really happy with the results now ( it took a bit of perseverance )Also running 139 scenars. For an estimated MV of 2600 fps

So I am sitting 2.5 grns above the recommended maximum of 40 .2
I did find that as you get close to your rifles potential max load, the sweet spot really kicks in. I will be watching for pressure signs again when the weather heats up.

Every one seems to love 2209 and it performs well too, but i love the way 760 meters.
