I've started my 338 Edge on a M70 Classic Stainless 375 H&H action. Originally it was to be a 338 Lapua, but alas, the bolt face cut out wouldn't be safe--it needed enlarging to at least the rim size--.588 of the Lapua. The Edge, being spawned from the 300 RUM and thus grandfathered from the 404 Jeffery, has a rebated rim like the 284 Winchester. At .534 the bolt face is OK as is.
M70's have owned me since the mid fifties; I just have to have that coned breech, claw extractor, and mechanical ejection. Its never let me down. But this year I was reminded of a drawback of the M70--and its brothers and sisters--from Peter Paul Mauser. That of the fact that it doesn't work very well as a single shot; the bolt needs to physically grab the cartridge to close it in the chamber. It was my fault because I "doubled" the bolt cycle; my mind was preoccupied with the moose I just shot and was moving rapidly attempting to get a finisher in while he was in an advantageous position for packing out. In the end I managed to get the extractor over the chambered round, extract it and examine, and re-chamber and finish the bull off. Again, my fault. So the truth is my "masters have been benevolent..." I digress; the best to you and your build.
And now for the "other shoe." I think it was you who told me how to initiate a thread/post just a week ago. **** if I can't remember how I started that Mill-dot or not--would you mind running me through that again?
Looking for a dependable laser rangefinder and it looks like it will be one of these: Vectronix PLRF 10 (OR 15), Pulse 360, or the G7 BR2. I'd like to get opinions, preferably based on experience, on these units. Hence the new thread. Thanks
