Well, I'm going to find out tomorrow; just returned from a Gander Mtn where I purchased all but one of their tins of #11 MAGNUM caps, as well as ( and much to my surprise they had them on the shelf) T/C maxi-hunters-I went w/ the 275 gr in .50 as 350 gr seemed like a big hunk of lead to me...any sense of a good charge for these or would my standard PRB load of 75 gr 777 seem reasonable? I only have 40 of 'em so I've got to get it settled in pretty quickly.
