No.... they didn't even exist when I was chambering it, to my knowledge. Google says, they are a very recent thing. That's about all I know about 'em. Is that correct?
I'm not recutting the throat regardless. That rifle shoots 162's absolutely lights out and I built it for hunting blacktail in the clearcuts on the wet side of the Cascades, high desert mule deer, and antelope. The 195 sounds fun but I'm not screwing with a good thing to pick up a minuscule amount less drift..... If my rifle doesn't get along with them, I'm booting the bullet, not the rifle <g>.
