Re: Carbon Barrels
I have used a good number of barrels by ABS on my custom rifles. Every rifle built to date has performed fantastic. I use only ABS barrels with Rock Creek cut rifled liners and routinely send hunting rifles to customers that shoot 1/4 moa groups. I currently have a 6.5-284 in a Lone Wolf stock that will shoot .2" groups at 100yds and 1.5"groups at 400 yds. This rifle weighs 5.5 lbs. Another 6.5-284 in a Nesika action and a Lone Wolf stock with a 30' ABS barrel, shot 2" , 5 shot groups at 600 yds. I have built rifles from 22-250 to 338 RUM, all with the same level of accuracy using these barrels. ABS also has unequaled customer service, any problems WILL be taken care of.
As for carbon barrels in general, the main advantage is obviously weight. However, part of ABS's patented technology is ingredients in the carbon fiber that disapate heat 300% faster then steel. You can not physically shoot a bolt action rifle fast enough, with an ABS carbon barrel on it, to get the barrel to critical temperature. This becomes a huge advantage in 2 areas. First is point of impact change with successive rounds. This does not occur with a ABS barrel, even in the big guns like STW and RUM calibers. Second, for varnmit hunters shooting alot of rounds, the barrel life is GREATLY extended, and there is very little need to let a barrel cool down while out on a dog town.
I am also of the personal opinion that heart of any accurate rifle is the barrel, most ABS barrels use cut rifled barrel liners, which no one can argue is the best type of rifling. I know that Christensen barrels use button rifled and to my knowledge so do Mag research.I also agree to call Bob at Lone Wolf, he will give you a honest, unbiased answer to any questions you might have.
