I used 53 grs of it with a 250 gr Speer in my 35 Whelen to take a nice 11 pt buck Saturday morning. 55 grs actually shoots a little tighter but at close range the deer don't appreciate the extra accuracy anyway. wink
I bet it would work well in the 220 Swift although I haven't tried it yet.
My old shooting partner used it in his 308 target loads years ago.

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
