huntinsonovagun Posted February 21, 2006 Report Share Posted February 21, 2006 Re: 7MM and 7MM WSM ballistics? I'm not AJ by any means, but I'll take a stab in the dark....I'm gonna guess that the WSM is only 200-300fps faster..... Quote Link to comment Share on other sites More sharing options...
AJ Posted February 21, 2006 Report Share Posted February 21, 2006 Re: 7MM and 7MM WSM ballistics? Comparing a 7mm WSM with a 7mm what? Using 140 gr bullets here are the different 7mm cartridges with max velocity loads from Hodgdon: 7mm Mauser (7x57) = 2715 fps 7mm-08 Rem = 2865 fps 7mm Express (280 Rem) = 2927 fps 7mm Rem Mag = 3107 fps 7mm WSM = 3133 fps 7mm Rem SAUM = 3153 fps 7mm Wby Mag = 3273 fps 7mm STW = 3347 fps 7mm RUM = 3353 fps Quote Link to comment Share on other sites More sharing options...

bearcat Posted February 26, 2006 Report Share Posted February 26, 2006 Re: 7MM and 7MM WSM ballistics? I don't know if it is a marketing thing or not, but Federal ammo lists all of the 7mm WSM loads at 100+ fps faster than the 7mm Remington Mag. Example 7mm Rem. Mag 140 gr-3175 fps, 7MM WSM 3300 fps. 7mm Rem Mag 160 gr-2950 fps, 7mm WSM 3050 fps. Winchester Ammo also lists faster velocities for the WSM cartridge. This makes the 7mm WSM equal to the 7mm Weatherby Mag. according to the factory listed velocities for each of the 7mm Mags. I don't have a clue as to actual chronagraped velocities, which will tell the real tale. Quote Link to comment Share on other sites More sharing options...
