I got no heavy bolt even at 46.5 but no doubt it's up there, I won't be investigating a load at that charge weight anyway as in this rifle it was quite unpleasant to shoot unsuppressed and un braked, and no I won't be threading this rifle I want to keep it as is.
At this stage I will persevere with the 45.5gn load and do a seating depth ladder or start agsij with a lighter pill, I'm inclined to try a seating depth ladder at 45.5gn as I already have the pills for that.
