I have a couple of them a 8 and a 10 twist, and was not aware that there was a problem above 3100 fps at least I never encountered it.
I shoot 120s, 130s and 140s out of my 8 twist and 3300 would be a mild load, the 10t shoots 85s, 95s, and 107s like a 220 swift on steroids all well past the 4000 fps threshold, so go for it.
