WOW!! impressive shooting there. And with that kind of powder charge you really had some interesting velocities. Pushing a .50 caliber conical over 2000 fps is just flat out impressive. That would flatten anything it comes in contact with.
I lubed them because they loaded do hard. I think without the lube I would have been loading them with a 16 ounce hammer. Funny thing in the Knight, once they were in the bore, they went down rather easy. Does Knight taper the bore?
What I really found interesting is that the changing or primers made a difference in POI and velocity. Excellent shooting and an excellent report.
