[QUOTE="65WSM, post: 782786, member: 9551"] I shoot two 6.5 WSMs. Before that I shot .264 Winchesters for 30 years. I use Norma .270 WSM brass. I think you are seeing lots of pressure. Why did you choose H-1000. I bought 8 pounds when then alive Bruce Hodgdon brought it out. Personal communication: "It was designed for 160gr bullets in the 7mm Remington Magnum." The original data in the Hodgdon book (we didn't have the Internet then) said 72 grains was maximum. We had quite a discussion with Bruce himself about primers and the maximum. I finally settled on 68 gr as my maximum with Fed 215 primers with the 160 gr in 7mm Remington Mag. I tell you this because there may be lot variations and Hodgdon's data may be actually hotter than is safe. That is unusual for the industry but with my lot was hot. I would recommend Retumbo (comes from the same plant as H-1000, ADI) for 120 through 160 gr bullets. Retumbo will produce higher velocities in the 6.5 WSM. Many shooters use F210M primers with Retumbo. I like VV N-570 for 140 and 160 gr bullets. I recently purchased the discontinued Sierra 160 SMP and Woodleigh protected points for testing. I can get 2900 fps comfortably. With 140 gr I can get over the old published .264 Winchester velocity of 3200 from a 26 inch barrel. VV N-570 is disturbingly coarse and difficult to weigh. Reloader 25 will produce great standard deviations but about 60 fps less velocity than Retumbo. The 6.5 WSM is still less volume and less velocity than the .264 Winchester cartridge. I hope you are getting your barrels nitrocarburized so you can enjoy some barrel life. I use only HBN coated bullets as well. My recent efforts are to make a game load with the 130 Berger VLDs. I have only shot the 130 Accubonds at game in the past. These go at 3300 fps comfortably. The Accubonds are a hard bullet at range (or the velocity is not adequate). Maybe the Bergers will perform better on small deer and antelope. [/QUOTE]
