RE: rem safrie grade ammo
The first time I heard of Swift A-frame bullets was when one of my customers went to Africa a few years back . . . they were heading out for Cape Buffalo and the guide wanted to know what mike had brought for bullets. Solids, of course, in the .416 Rem Mag. The guide was pleased. He said only solids or Swift A-Frames were allowed for Buff in his camp. I thought this was a pretty telling endorsement. He didn't even mention Nosler Partitions or Barnes X bullets . . . .
I have seen these bullets used in standard North American calibers on elk. They have tremendous penetration and bone-breaking ability. I have heard of them passing through two elk broadside. And in another instance, going through one end-for-end. But have also heard of them not killing very quickly on broadside lung shots. I guess there is no free lunch.
So, in your case, I would say they are a waste of money for deer hunting - but might be worth it for some of the larger African plains game - or for elk/moose if you like the shoulder shot. Or for big bears if that's the biggest gun you have.
