.303 vs .577-.450
I would agree with Webley MkV regarding the "romance" of the original big bore black powder caliber, but for the price of brass. IIRC .577-.450 new brass is something like $80 or $90 per 20. I have lots of good Greek once fired .303 and I'm looking for a cast bullet shooter. I had an owner of a .303 carbine tell me the carbines in .303 do well to shoot 3" groups at 50 yards, but that seems pretty sad for any rifle - at least if you work on the load.
Anyway I ordered one of these yesterday. I'll let the group know what I think of it when it gets here. Shooting might take a bit longer, depending on weather and time away from "honey do's" to get to the range.
