The 7.62x54r of the Mosin is a notorious “disemboweler”.
Now that sweet Sig is close enough to be called AK47 variant. More in common with it than the Vz58 for sure. It is what an AK should be.

I have a Nagant that I sporterized by taking 3” off the barrel, composite stock and a Burris 2 and 3/4 scope on a scout mount. With 200 gr. soft points it kicks like a MF’r but I wouldn’t hesitate to take it where I might encounter critters with big teeth and nasty attitudes.
