I have never gone to the point that Mainer did, but full pressure loads were flawless in the BLR, extraction was quite easy. My hunting loads are full pressure . It is a gear operated bolt action rifle. Obviously it can be somewhat more difficult to extract than a turn bolt .
I now have 3 of them, I also went from the Marlin 1895 45/70 to a BLR .450 because I had not fully trusted the action of the Marlin. Great post Mainer
