I loaded some before the 45gr load was published and ended up with a hotter load which showed no pressure signs in my rifle.
I have since wound the load down and have one just below 45gr. All three loads averaged around the same 0.850” 5 shot groups as do most of my loadings.
I was using Lapua brass. I did have a box of factory that chambered normally and shot much the same but were very notchy to extract. They were in PPU brass
