Re: McGowen Barrels ??
I've only ever heard 1 negative comment (was from a smith, if I recall). It had to do with slight differences in bore diameter, lot-to-lot, and also within lots. But not any within a single bore. Take that for what you will, as the REAL test will be how tightly it groups the shots. My own testing will commence this coming week, following super sunday. It took a bit over 3 months to recieve it, once the order was placed, back in october. By comparison, that beats out hart by about 6 months, and by about 200 bills (finishing costs included). I went "pre-fit", with the "remnut" feature. This means that it goes from them to me, and then from me right on to the R700 action. No smith, or smithing, is needed! I do apologize, as most of those who do read this RB&B forum probably ARE smiths.
The barrel is SS [as is the nut], with a bore of .284 (7mm), chambered for ultramag, and having a twist of 9. Length is 32", muz dia. is 1.2", and crown is non-recessed target.
I'll chime in again, after some papers with holes in them become avaiable.
