I have had four of them, I think. Arch 1965 got one of them I think - was that the custom rig Arch, or one of the 700s?
Two were 700 BDLs and one was a 700 Classic IIRC. All of them went west after I played with them. I never did shoot any living creature with one, but I found the cartridge to be very accurate, and was convinced (and remain convinced) that the 8 Mag was adequate medecine for anything that walks the planet.
IIRC the best performance for me was with a Norma Dual Core bullet right around 200 grains, perhaps 196??? Arch got a lot of interesting bullets from me including some custom 250s......or so this poor old brain thinks.
Conclusion: I think it is a great cartridge but pretty well all of the detailed memory on it is long gone......and so are the guns!
