Group sizes ? oh some here, some over there . Didn't pay attention
to that, I was more interested in hitting the 2' x 4' cardboard backing.
Really groups are about 3"-5" got one pair side by side about 1", all off hand.
These were using 15 gr loads and .323 , .325, once I fiqured out the POA.
But they all hit inside the 2'x4' target.
Powder & ball only no wads no lube.
