[QUOTE="Max Heat, post: 903634, member: 43153"] After more than 1/4 year wait (for those not born with the virtue of patience, the waiting IS the hardest part), my new McGowen barrel has finally arrived. It is 1.2"straight-cyl stainless rem-nut style in 7RUM, with 9" twist and 32" length. When I first laid eyes on it and saw how much of a "shiner" it was, I immediately realized that, cosmetically speaking, I screwed up by forgetting to order the blasted finish. Now it won't match my action, and there is no way that I'm going to be comfortable using such an eye-catcher out in the field. I'll wrap it [along with the equally-bright nut] with camo tape for now, and see how it looks without the rest of the rifle being camoed out. But doesn't a blasted barrel have the advantage of being able to cool itself more quickly, due to the larger surface area imprinted into it by the blasting precess? ◙♪◙♪ Another concern is that, looking down the barrel, the rifling lands "appear" to be less substantial (thinner and not as tall) than what I normally see. Is this possible? And if so, wouldn't that promote quicker burn-out? With the over-boar-ed-ness of 7RUM, along with the hot loads that I usually run, burn-out is already a significant concern that I have. [/QUOTE]
