I've been thinking on using my 45-70 bolt action, a Siamese Mauser conversion. I have some hot 350 grain factory loads that I can hit clay pigeons with regularly out to 300 yards.

Those square bullets sure lose steam fast. I'm wondering if penetration will be adequate at the longer ranges....dunno. Still thinking on whether to take the 45-70 or a different rifle that shoots that has tall cartridges and pointy bullets.
