I have a custom AR15 in 6x45,(RR Lower, 3# trigger, 22" custom barrel) that just will not group no matter what load combo I use. On the rare occasion that a good group(1/2" to 3/4") does present itself, I can never come close to duplicating it ever again. Another interesting issue with the groups is the sequence that it "throws" a round way out...it will 99% of the time throw the second shot...this is without fail. 1st shot, then second shot goes 1" to 2" right and sometimes high(every time!), third shot goes back to either touching first shot or within 1/4" to 1/2" of the first shot. This is group after group with all different powder/load combinations. Powders used have been Benchmark, H4895, 8208, Lake City and Remington brass, CCI450 and Nosler 70gr BT's primarily.
Now, I have 3 other AR15's and none of them exhibit this behavior...20 Practical AR, 223 AR and both are honest 3/4" guns with several groups under 1/2". I have a 17HMR AR and depending upon wind is an honest 1" or less and will out shoot the 6x45.
So, with this said, what could be accounting for this 6x45 AR to be grouping like this...primarily, why or what is going on that the 2nd shot is ALWAYS a flyer? This is not just one or two groups...I'm talking EVERY group...several hundred rounds of groups without fail ALWAYS throwing the second shot way out, to the right and sometimes high. Is it the gas system, barrel or barrel torque? I can't imagine a bad barrel doing something this consistent...so what could be causing this 2nd shot flyer every time? I don't have anything like this going on in my other AR's, so I am ruling out shooter error...not that I haven't buggered up a few good groups but even I couldn't be this consistent with throwing EVERY 2nd shot out like this.I have several hundred rounds now thru this AR and it doesn't seem like it is going to "come out of" this issue...I know I can send it back to the builder and get taken care of, but wanted to give it a thorough chance to "come around". Would also like to know why on the 2nd shot
Thanks in advance.
