I have one in 338 Rum. I ordered this barrel on April 3, 2017, and didn't receive it until sometime in late August. When I ordered it I called and talked to Gene Gordon. He was very nice and was able to accommodate all of my requests. He stated that I should have the barrel in 6-8 weeks. After that time period I started emailing him, he always said we are working on it, and you will have it in a couple weeks. This kind of ****ed me off. If he would have just told me that I wouldn't have it until August it would have been way better. The barrel I ordered is a Remington sender contour in a 1-10" twist as they didn't offer a 1-9". I wanted to shoot the 300 grain Berger,I have shot this bullet out of other 1-10" barrels just fine so I didn't think I would have an issue. When I got the rifle together I started working on loads. It shot the 300 horrible, like 3" at 100 yards. Next I tried the 285 hornady, guess what still horrible. By this time I was really ****ed. My bother and I both figured the twist was too slow, so we measured it. Sure enough it is about 1-11.25". Then I tried some 250 grain bergers, the first 3 shot group was 1/2". I had an early season elk hunt planned on the 15th of September so I just figured I had to live with it. Having said that, the fit and finish of the barrel is amazing. It is every bit as good looking as a proof. I wouldn't hesitate to order another barrel from them. I would just tell Gene when you order it to not lie about the delivery date.
