220 Beggs Trimming?

[ASbobcat]

I believe the Beggs chamber is supposed to reduce case trimming vs 220 Russian. Anyone out there with enough experience with it to provide actual information?

I HATE trimming, but want to avoid fire-forming PPC if possible.

Alternatively considering pushing 220 Russian shoulder back to 22 Waldog.

Intended purpose is 300yd BR.

Thanks

I have a 6 Beggs barrel but never shot it enough to say. It was popular at the time to reduce the radius at the neck/shoulder junction and that supposedly helped with reducing case growth. That seems to have fallen out of favor and you see more standard dimensions there in current chambers. I did the same on a couple of other reamers and can't say it was any better than anything else. I discussed this with Dave Manson and he had his doubts but ground it anyway because that's what I wanted to try.

Still grows a bit, requiring trimming a bit more often than most br related cases, IME. The taper of the case probably is part of it but so are the dies. So, depending on how hot ya load, you either size the brass enough to do away with clickers..but need to trim a bit more often, or, ya load mild, size less, trim less often, and still get clickers due to not sizing it down enough.

Its a good cartridge but it grows more than most, but not terribly. That's my experience anyway. It has a lot to do with die to chamber relationship and how hot ya shoot it. Same can be said for virtually every cartridge but the Beggs family is just a tad more needy in that regard than most small cartridges for br work.
