any experience with .338 5R Rock Creek barrels?

My EDGE is due for a new tube. I told my smith that and he mentioned he had a sendero tapered Rock Cr., 5R, fluted and could finish it at 28" at his shop. My current barrel is a hart and I was leaning towards a Kreiger. Does any body have any experience or thoughts with the 338 5r rock?

Mike Rock (Rock Creek) 5R barrels are excellent barrels. I wouldn't hesitate if it were mine.

If he has any Rock Creek 5R .284 caliber 1:9 twist stainless fluted barrel blanks sitting around, let me know...I need one for my .280 Ackley Improved build.

I have chambered a few in 338 Edge, they were all good. I mainly use Brux though

Re: any experience with .338 5R Rock Creek barrels?

I've had a 29" finished .338 Rock Creek barrel for several years. 338AX made by Kirby Allen. Unless I had a discussion with Rock Creek about the width of their lands first, I probably wouldn't get another. We found that the lands in my barrel were extremely wide, giving something on the order of 40% compression to the bullet. As I recall, Kirby like barrels more in the 21-24% compression range. I don't know if my barrel was unusual in that regard, and it's accurate enough, but the larger bullet compression has got to up pressures/reduce potential fps. Just a thought. Might have your 'smith measure the width of the lands and compute the bullet compression first.

I appreciate the feedback. I will do some homework on the lands, I realize it is a ford, chevy question.
Jmden,
Does your rock 5r meet your standards for fps or did you pressure out before ideal velocity? Thanks fellas, brent

Yep, I have one and it's good, I've had another one ordered for going on three yrs. So many stories it has become a joke.
