I've never shot one of these until yesterday, I tried 90 grains goex 2f and the results were horrible. Only 2 of 3 shots even hit the target at 35yds, no idea where 3rd shot went. These are a 400 grain hollow based pointed .54 mini, I was shooting them out of a TC Black Mountain Mag with a 1-38 twist 26 inch barrel. before I waste any more of these bullets thought I'd get some advise. Do they normally like a lot of powder? fast or slow twist? these bullets practically fall down the barrel, this normal? loose enough I'd be a little worried about them sliding up off the charge if I was hunting. These are a good looking bullet and should really put the hurt on a deer, hopefully I can find a way to use them.
