This is a custom die by Buffalo Arms where they use the Lyman die as the donor die.
I did try and size a few nose first but the results were the same; .3675" to .368". I did order a Lyman, .363" from Buffalo Arms, to size just the front driving band.
Today, I took 10 loaded rounds where the bullet was seated so the front lube groove was exposed. This puts the base about 1/2 down the shoulder, exposing the sides, just above the GC. To chamber the round I had to smartly run the bolt home to get the round to chamber. Unseated one, pulled the bullet, fortunately throwing most of the 52 gr charge of Varget, clear of the action. Glad I had the Sinclair Reloading short brass rods set with me to get the bullet out of the throat.
Gave 2263 fps with a 170 ES from a 24" #3 PacNor. Zero leading after 9 rounds. Accuracy sucked. I shot this mostly to zero the scope @ 50 yds.
