Nope, you are following book charges that over the years seem to get lower and lower.60gr going that quick? Blimey, that's good. A slightly over max charge of N130 pushes a 50gr Sierra Blitz bullet to around 3120fps for me. That was measured on a Labradar at Bisley, too, so I guess accurate. I wonder if my barrel is particularly slow?!
My 55 gn ballistic tips use to be 3200plus and I thought it was slow!
A friend of mine had his 222 doing 3940fps with 40gn ballistic tips.
No dangerous pressure but high pressure. Brass only lasted about three reloads.
