[QUOTE="Bruce A., post: 494191, member: 32880"] In the last year I have been working with the 7828. It was better than previous powders I'd used, but the problem appeared to be the heating of, what I considered, a very thin barrel. As I said, if I let the barrel cool for 30 minutes between shots, one minute groups were possible. I tried bedding the factory stock. Later tried an overmould stock and now have it mounted in a Choate Tactical which is free floating (and this stock handles the recoil very well). The OEM stock had a intentional lump in the fore-end that put upward pressure on the barrel. Removing that and later re-creating it with the glass bed made no difference. I am really looking to create a rifle with the 1000-1200 yard reach and accuracy of a 338 Lapua Tactical rifle. I tried the 8mm Mag on a thousand yard course a couple of years ago. No one at the range, including another fellow shooting the same OEM Remington 700 as mine in an H-S Precision stock, could understand the poor accuracy. He checked chamber alignment and head space (an awesomely equipped, for being on the range, long range shooter) then tried his ammo in my rifle. His rifle shot -1/2 minute. Mine shot 3-5 minutes with him shooting it. He was truly puzzled. [/QUOTE]
