Re: Help with my 6.5 long range gun.
The 6.5/300 Steve Shelp and I have had lots of experiance with.
Al Hoyer built his (most of them) on a Winchester Md 70 actions and used Douglas 28" Stainless barrels on them.
He did find out early on that, the 8 twist was the best for the heavier bullest.
I just sold a Hoyer Gun chambered in the 6.5/300 Weatherby and the load it liked was 83 to 87 Grs of WC872 (H870 is about the same but go 2 grs lighter) and the 140 Gr or 142 gr Sierra MK. 83 grs in the summer and up to 87grs in the winter.
That combination(87 grs and the 140 or 142 gr) is deadly in the winter time shooting across the mountains of PA. after whitetail.
The 8 twist is a must in the 6.5/300 using 140 or heavier bullets.
Good luck and good shooting.
By the way, I still have two 6.5/300 Weatherby's and like them a lot. The 6.5 Gibbs and the 6.5/06 are also very good. I can't seem to get away from the 6.5 for very long.
