I had Jim at Center Shot do some work on my Sendero 300win mag. He put EGW bases and rings on it. The scope is a Zeis 4.5x14x44 rapid z-800. The both look good and work great. I have not been able to post picture - If you want pm me with your e-mail and I will send you pictures.
I have a few sets of PRW rings and bases. They are plenty stong. But if you are going to get into long range you might want to get a rail as teh last poster suggested, with a bit of elevation built in, something like a 20MOA rail with the PRW rings. I have been eyeballing a Nightforce Unimount for the remington 700. Looks like it would be very strong and should take care of lapping the rings (maybe). I think the term `best` depends on what you want.
I have a M700 with a Seekins base (20 min) rail and a set of 30mm rings. Do to the physical size, I chose aluminum. This brought the wieght back down to the nieghborhood of a steel Leupold 1 piece base and rings. The workmanship is very good and I am a happy camper.
I shoot a 300 RUM, Hornady 208 gr AMAX at 3164 fps.
The rifle holds zero and shoots very well.
yes I just bought a set from Glen. I can't say enough about his level of knowledge and the quality of his product. I do alot of research before any purchase and he is by far the best. Nightforce is down the road from me and I like there stuff to but the big bolt on the side of the rings hang up on everything. Glen's rings are smooth and the way the ring is machined were it fits the rail is way better setup then nightforce.
