Well it sounds like you have a real good load going there.That will really put a worldof hurt on about anything you want to hunt with it.
I shot a few maxiball out of the Lyman mold myself today. I was only shooting 70 grains of Triple Se7en. I was using a .54 caliber Renegade and the 405 grain maxiball. In the photo I labeled them a 370 grains and now just remembered.. .54 caliber bigger bullet..
I also shot some 380 grain R.E.A.L. conicals with my homemade beeswax/castor oil lube. My old Renegade really likes the REAL's so I knew they would shoot a good group at 50 yards. Although the rifle was shooting a little to the left, so I corrected after the first three.
Good luck elk hunting.. I bet those would work real well on hogs and deer as well...
