I went up 67gn, no pressure signs… it felt like a really mild charge compared to what I was getting with factory ammo… I am at the 4th firing on some of the brass, primer pocket getting loose but are still ok. Again nothing as bad as some of the factory ammo.

I think you are correct about large vs magnum large. A mate using H1000 with large instead magnum is also couple of gn past max charge
