Good info Lefty.... I totally agree.
The Kimber MT .270 WSM I had kind of mirrored leftycarbon's experience. The times I shot it at 1,000, I hit a 13" gong around 40%, with most misses coming horizontally. However, the same rifle would hang sub MOA at 550 yards consistently, with very acceptable vertical deviation.
I guess what it comes down to, is to explore your limits, and know your limits with every rifle you own.
One of the best things I ever did was start spinning turrets on a .270 cooper shooting 140 grain beger vld. I think it was JB who said to stop analyzing rifle gack and start shooting what you have. So I did. A lot. 600 is where I stop with that combo.
Cooper makes a great rifle but, that sucka is heavy and I'm tired of carrying it on 9 mile hikes.
