Re: Anyone shooting a .300 WBY
I had Dave Kiff @ PT&G make me a reamer last year that works great. The reamer he recommended was a 4 thousands clearance over the neck, .248 fb (w/ .3085 clearance), 1 and a half degree taper. This combination works great. I had some skepticism having undesirable results with two other 300 wby mag reamers (manufacturers other than Dave Kiff)...but Dave practically guaranteed the accuracy since (according to Dave) it was that set up that a lot of the guys that shoot benchrest in PA shoot that configuration.
Tried two different barrels (kreiger 1-10 twist) with two different rifles...the results were great. I get great results with H1000 powder appx 3060 fps w/ SIE 210 gr SMK, Berger 210 gr VLD, 200 gr SGK (hunting). A friend of mine that shoots a 300 wby (same reamer) shoots H1000 w/ 180 SIE SGK @ 3220 fps.
Highly recommend a 300 Wby Mag with Dave's reamer configuration.
The results are great @ 1000 yards but from the looks at the velocity and BC, the Berger 190 VLD might have less wind deflection and drop than the SIE 210's that I play with. Might want to give the 190's a try.
