Home Forums Lever Action Central Big Bore Levers calibers considered big bore

I consider big bores to start once you get past .375", using the bore diameter as a measure instead of case capacity.

No doubt the .300 WinMag is a powerful round, and I consider it a big case but a mid bore.

Just my thoughts on it.

I've used rifles in .348, .444, 44 mag, and .45-70. Though the .348 is a mid-bore, it is powerful!
