[QUOTE="vegas steve, post: 655969, member: 47484"] my gain twist pac nor supermatch barrel with an 11 degree crown shot consistent groups in the .080 to .095 @ 100 yds using sierra flat based bullets. i worked on loads for quite some time using similar weighted,better coefficient boat tail bullets like burger vlds and never reached this kind of consistency. when i stretched the groups out to 750 yrds i seen the same difference in accuracy between my best flat based load versus my best boat tail load,which from a physics standpoint should not have happened. my spencer and my schneider barrels netted the same results.the flat based bullets should have fallen out and strayed at 750 compared to the boat tails, but to my amazement they did not. they shot remarkebly better even at this distance.
