I have exchange several e-mails with Todd Bettin (Bettin Custom Guns) about building me a rifle. I was up front and asked him about the differences in the ABS Barrel vs. the Christensen arms carbon wrapped barrels. I realize he is trying to sell his product/service, but he gave me pretty much the same answers that your have read on this forum. Christensen's do not shoot consistently.
There is also a difference in the way they wrap and the materials used. There are some articles out there which tell you about these differences. I believe it was in "Popular Science" magazine that there was an article about the process as well.
There are several other custom rifle builders that use the ABS method (Jense, MPI). I am sure any of them will give you the same story. It is actually quite interesting to read for yourself. For instance, carbon fiber actually holds heat and shrinks when heated. I guess you can imagine what that does to accuracy. ABS system eliminates this inherent property of the carbon fiber. There are also different qualities of carbon fiber as well.
I have not talked to anyone at Christensen, but the builders that I have talked to about the ABS method are very open about their method and materials. used.
They are more expensive, but you pay for what you get. Bettin guarantees 0.5 or less with his rifles. He is very accessable and willing to answer your questions.
No problem. What caliber are you thinking of. I was going to go with 280 AI but have changed my mind on to 6.5-06 AI. I have a semi custom 300 Weatherby for large game shooting 165's and 180 grain bullets. I had only planned on shooting 140 grain bullets and the ballistics are better with the 6.5-06 AI with a 140 grain bullets compared to the 280 AI.
I already have a Remington action from a 30-06 I am going to use as the foundation. I wanted something really lite but would shoot long range, that is why I am going with the ABS barrel. It will be my new deer rifle. I have a 270, but I have always wanted a custom rifle with all the Bells and Whistles that I desire.
In a couple months I will be shooting a Savage I am having built in 260 AI for my practice gun to start my long range shooting (beyond 300 yds). It is going to be a heavy barrel gun. Since Savages are so easy to change barrels and inherently accurate out of the box, it will eventually be my varmit rifle.
I'm thinking of either a 7mm remington mag, or 300 wsm. I'm still researching and they seem very comparable. But, I haven't decided on an action. I have it narrowed down to 2, remington 700, weatherby vanguard, but just cant decide haha.
Unless you know something I do not, which may be a lot LOL. I do not know a gun builder who will use a Weatherby Vangard action and Blue Print it. I know of some that will do a Weatherby Mark V action. All of them will do a Remington 700 action. Jim
Weatherby vanguards are the same as Howa and are very good actions. actually IMO the Howa's/Vanguards are a better design, and are very workable as donor actions. The down side to them is that there are way more readilly available aftermarket parts for the remmy. I have had both. you wont be dissapointed with either.
