First he didn't hit the gong once. He spent a good amount of time shooting once at the ranch also. He had a full week before his hunt. So he shot out past that but was able to consistently hit the 6" at 600 with no
Misses.
Second I know it's on the lower end but it seems that the min FPS is a pretty good judge based on This and several other times. He was able to place it exactly where it needed to be and it had a full pass. I'd say that it was fine. Best for situation no of course not but when that's all he had in that situation is take it.
Again he is the type of guy that if he didn't feel very confident he could keep off the shoulder he would not have taken it.
He will indeed have a 30 Sherman next year.
This wasn't to be snarky either I do agree big is better especially if any wind is present. Just wanted to make sure the fact where out. Because I 100 percent agree hitting a gong 1-2 times is not ok.
He left with a bunch of ammo just so he could practice and double check everything at given elevation and at farther distance
