[QUOTE="65WSM, post: 1833328, member: 9551"] I am familiar with both the .264 Win Mag and the .257 Weatherby. If you have to have a belted magnum, for reasons unknown to me, I would pick the .257 Weatherby. It has a longer neck for partial neck sizing and more magazine room for the spitzers. Longer necks are also heat sinks to protect the throat of the barrel. R-Bros (builds 3-5 hundred custom rifles a year) for his own deer hunting builds 24 inch barreled 6.5 WSM and with Reloader 26, gets 3300 fps with 140 Bergers. With a 6.5 WSM the bullets are more likely to seated to shoulder instead of deep into the body of the case. The 6.5 SAUM and the 6.5 PRC are also great deer cartridges that will fit into magazines. Long range (500 yards) at my club range, I can group better with handloads built on modern beltless cases than I ever achieved with the .264 Win Mag. From a 26 inch barrel (or even a 28), I can get as much or more velocity from less powder (9 grains less) than I can from the .264 Win Mag. That means less recoil and muzzle blast. Nitrocarburize the barrel and shoot coated bullets. No naked bullets! [/QUOTE]
