In the big bores I have quit loading and pursuing accuracy.
If all the bullet holes touch each other at 300 yards, that is good enough.
After that, just focus on terminal target performance.
Maximum hole depth and hole volume.
A well-constructed 600-grain bullet hitting the target with a retained velocity over 2,400 fps within an inch of the intended spot can make up for some misplacement.

Works for me.Quote:

Hammer,
I have tried what you are suggesting, problem I have been having is my 20 cal 600 grain bullets are slowing down my feed rate. having to hand screw 7.70" of bullet into my rifling prior to shooting is getting real old. I am also not getting anywhere near the 2400 FPS of velocity that you are discussing. I may have to try Retumbo of something in that burn rate.

WOW! And just what twist do you have on that barrel for a 7" bullet?? :oQuote:

I don't know Hammer, sounds kind of sloppy to me. ;D
