My first 7.5 was a standard 4 groove and was really hard on the 150's and 147's. I was blowing up jackets pretty often. Muller created a modified land profile and the problem is now solved, but it took a while. Pretty cool to have 4-groove accuracy that's easy on jackets like a 5R.
I'm still running a couple of modified 7.5's and having good luck personally, but we ended up running a bunch of 8's while all of that was being worked out. Really did not see a downside to the 8's up to the 147 class bullets when it was all said and done.
