Re: 338 RUM performance
I wanted a .338, but I wanted it in the Remington Sendero. I am totally sold on the Sendero as being the finest over the counter rifle built, primarily due to its full length aluminum bedding block. They are amazingly accurate right out of the box, and the improvements they made in the second generation have made them even better. I have three of them and they all are tack drivers as is the .257 STW I had one of them converted to. My problem was that Remington does not chamber their Sendero in .338. So I bought a .300 RUM, took it over to Benchmark barrels, and had the .300 barrel taken off and the .338 screwed on. (And that is all you have to do to make the change.) I added their brake, and it shoots .5 MOA groups with recoil in the .243 range. Can't beat it IMHO. I like it better than my CZ .338 Lapua.
