[QUOTE="J E Custom, post: 183784, member: 2736"] [b]30/378[/b] John The primers that get the most velocity are the Fed 215s. The best standard deviation has been with the Rem 9 1/2 mag primers(5) but at a loss of about 30 ft/sec. As far as powders the slower the better ( H869, H50BMG) except H870 I did'nt have any luck with it. Premium Bullets in the 200gr to 225gr range (Nosler partition in 200gr & 225 or 200gr accubonds would be my recommendation. The real trick to building a Weatherby that shoots is minimum head space (.001 or less) and with the standard Weatherby freebore you can load hard for velocity, Please let us know what velocity and performance you get with that long barrel. Good luck J E CUSTOM [/QUOTE]
