I just got some Hornady 68gr bthp match
is very inaccurate in 1/9 twist 16" middy
talking 8 to 10" groups at 100 yards - not joking
68gr hornady bthp match
26.6gr W748 gives 2850 fps
loaded to max oal to fit GI mag
On the other hand, the rifle is capable of MOA, perhaps even sub MOA
if I do my part even handicapped with a 2MOA red dot
with
55gr Win fmj bt wc
26.6gr W748 gives 2750 fps
loaded to 2.223 inches
Win SR Primers
S&B cases
First question is: how can I load the 68gr so it performs even decently...or as accurate as it should.
Second Question - Am I simply loading the 68gr too long?
PS - the chamber is tight on this AR
by tight I mean when a round is chambered, it is real hard to extract it by pulling on the charging handle. It does extract properly when fired.
yes, I am FL re-sizing with Hornady dies
