Took my CVA .50 caliber Hawkins and the .58 caliber Buffalo Hunter out to the range today. Started easy at 25 yds just to make sure they were sighted in. Both hit the bullseye with no problems so I moved over to the 50yd range and that's where the accuracy went to heck. My load for the CVA was 55 grains 3F with a .490 PRB and pillow ticking lubed with bore butter. I worked up to 65 grains and the accuracy got a little better but it ended up shooting 8 inches high.
The .58 Buffalo Hunter shot ok ( hit the paper) with a 320 grain minnie ball over 50 grains of 3F but when I switched over to a .570 PRB I couldn't hit paper. I tried working up to 75 grains of 3F but still didn't have any luck. Got tired of wasting powder so I called it a day.
I don't know if I sabotaged myself because I tried some 50/50 bees wax olive oil as a hard lube early on in the day with both rifles. I didn't notice any fouling, loading was easy all day long. Any thoughts?
Thanks
