My Rifle Setup for Buffalo and Plains Game - Very Soon

[IvW]

I'm reading that 416 Rigby has a 14.99 mm rim and 300 H&H and 375 have 13.5 mm rims. Not the same. I have questioned just how much "slop" is allowed on a bolt face before extraction and/or ejection are compromised. Haven't found a good answer yet. The instructions from Duane Weibe's book for converting standard Mauser action military rifle into thumper dangerous game rifle specifies opening the bolt face and extractor just enough for a fully loaded cartridge to remain suspended on the bolt face of bolt removed from the action.

That No 1 is deceptively heavy. This 404 Jeffery I built on a standard 98 Mauser with heavy #5 profile 24" barrel, lots of wood, 30mm scope, rail, QD rings, and fully loaded with four big cartridges weighs just slightly less than ten pounds.

Yes. We sorted that out via PM. I didn't read his post carefully. Oops.
