[QUOTE="buffalorancher, post: 146999, member: 5771"] Well, it was a nice day for shooting prarie dogs yesterday. Maxed out at 60 deg. with light and variable winds, not bad for northern Colorado. The A-Maxs wound up performing about like Kirby said they would. The first five shots were dead on out to 417 yards then the bullets started wobbling about 1 out of 3 times and hitting the dirt all over the place. This went on for about 15 shots then they started blowing up until they did it every shot. All this happened over about 3 hours with the temp steady except for a couple rounds that showed ejector marks from getting warm in the sun. These barely made it out of the barrel if at all. The build up in the barrel seem to be the culprit that pushed them over the edge as I started cooling everything down in the AC to see if it made a difference and it didn't. I am dissapointed as the bullets seem to perform well when they stayed together but if I need slower velocity I would have built a **** 243 and not worried about it. It seems the 6-284 works better with slow twist barrels and light bullets going like hell. I think I am going to slow the A-Max down or try the Berger but I would have to agree with Kirby on the barrel twist after my experience. The few SMK's I had shot great after the blow ups so I have that option and the prarie dogs didn't know the difference. On a completely difficult note, I wonder how hard you can push the ABS barrel as you can't tell how warm it really gets. I remember the post with the thermal camera but it makes me nervous blasting away so I try to avoid it but when you miss a PD by inches way out there you have to keep on him if he let's you.
