I dont know as you'll find too many a worn out blaser barrel. Most hunters aren't running them until they are glowing red or shooting thousands of rounds through a blaser per year. I could be wrong though. The other flip side to this is that blaser's barrels are made of tremendously strong steel alloy. Probably something with the strength of an vanadium/nickel HSLA or similar alloyed steel but with the properties of an abrasion resistant steel. They aren't your standard 4140 chrome molybdenum steel that normal barrels are made from. They hold up to lots of abuse and have been tested to 200,000psi and hold up just fine. My guess is that they arent easy to shoot out.I’ve looked at a couple. 1000$+ for a barrel is way too expensive since I can buy aftermarket stainless blanks for 300$ or a couple dollars less. Any caliber and any contour. Then it’s just my time and tooling.
As to whether they are better than other barrels... an overpriced item doesnt sell in a free market. It is too expensive for what people get, yet Americans still buy blaser barrels and rifles and those that have them, love them. I think this video speaks pretty well of the differences between american rifles built to a price point and European rifles built to a quality point. They don't let their sales team lead the engineers around by the nose. The engineers build the best product they can and then the marketing team has to sell it.I’m more thinking I can stick a blank in a CNC and cut the recess for the bolt and flanged locking collar, plus with live tooling I can drill and tap holes for a pic rail as well as drill and tap for the studs that go into the stock all in one tool holding.
I also seriously doubt Blaser has come up with anything drastically new in the barrel material world. Hammer forged barrels have been around awhile, and barrel hardness only buys you so much. If Blaser barrels were markedly better than all other barrels then US shooters would be buying them by the truckload. In my experience hunters just shoot barrels much longer than target shooters since the accuracy expectations are not as high (exceptions do exsist). Same thing with chrome lined barrels in machine guns, I can’t remember the exact number but the military runs their 223 and 308 machine gun barrels past 30k rounds…….but I can guarantee you a 223 will not consistently hold 10ring (12in)at 600yds past 2000-4000 rounds (depending on brand, bullet used and how hot the load is). Fclass guns are lucky to make it to 2000 rounds but again the expectation of accuracy is higher.
Ask someone who has a blaser R8 barrel and a micrometer to get you the dimensions. I don't have one but if I did, I could whip a drawing out in solidworks for you quick with the dimensions on it. someone here can likely help you out with dimensions.I’m hoping for one that shoots 6”. I’m not looking for anything serviceable. I just need dimensions off the back end. The bore could be completely smooth for all I care.
