[QUOTE="Len Backus, post: 29061, member: 1"] Next chapter: Well, I wouldn't have believed it! The A-max bullets are vanishing before they hit the target in one out of 4 firings. I reduced the velocity from 3300 down to about 3100 and it's still happening. THis is in a 9 twist barrel, hardly over stabilized. Even went to the bullet store (one hour each way) to get a different lot. Same result. No wonder it seemed like my groups were so tight, although some still were. One of them was an honest 1/4 inch with at least 4 and probably five bullet holes. Final proof was in setting a target closer at just 30 yards away. Result was a bit of a jagged hole and some dark gray smudge just under the bullet hole. [/QUOTE]
