I have a CVA Accura 50 caliber that shoots 295 grain conicals (actually Powerbelts) very well with White Hots. I thought I'd like to shoot something cheaper, so I picked up some Hornady .490 round ball and some Cabela's .010 patches. I tried them with the White Hots and the gun spews them all over the place; the group is about 15 inches at 25 yards.
Is this just inherently a bad match - something to do with twist rate or rifling depth or whatever - or is it worthwhile to continue playing with this, using a different propellant and charge, or whatever?
The CVA has a 1:28 twist 27 inch Bergara barrel. I'm getting about 1550 or so fps on the Powerbelts. I haven't chronographed the round ball.
