[QUOTE="Bruce A., post: 964679, member: 32880"] OK, I had the Douglas barrel installed by Douglas. Figured they would do it correctly. First trip to the range was shooting loads I'd worked up in the old factory barrel. Accuracy was phenomenal. Half minute groups at 200 yds. But, way too hot for the new rifle. Ten rounds fired and the brass from all were trashed. This was all new brass. Primers did not appear to be excessively flattened, but the brass extruded into the ejector button leaving a "polished" spot on the head stamp. After depriming, the primer pockets would not hold a new primer. With the rarity of 8mm RM brass this was a costly loss. Recoil had been tamed with the medium target barrel and the cases extracted smoothly with normal operation of the bolt. I was paying too much attention to the group rather than looking at the cases. Oddly new loads with the reduced powder charge are not as accurate as the over pressure stuff. I am looking for new powder and bullet combinations to extract that full accuracy. Some of the suggestions in this forum will be tried. Let me clarify, the rifle is accurate to 1 minute with which any fool should be satisfied...just not seeing the >1/2 minute of those over pressure rounds. BTW, I have broken down all the remaining box of that high pressure loads so's to remove the chance of using one again. [/QUOTE]
