[QUOTE="DMP25-06, post: 2578794, member: 27271"] I would like to share a page from a NORMA Powders reloading Guide on loading for Weatherby Magnum cartridges . This Norma Guide is from the year 2008 , if I remember correctly . On Weatherby Magnum Cartridges , beginning with the .240 Wby. Mag. up through the .416 Wby. Mag. , only Norma MRP (Magnum Rifle Powder) powder is used , and all except the .240 Wby. Mag. use the Federal 215 primers . The .240 uses Federal 210 primers . This reloading information is also the Load Data and components used in NORMA Factory Loaded Ammunition for their Weatherby Magnum Ammunition . Please note the velocities of the .300 Wby. Mag. with the 180 gr. bullet showing a max. velocity of 3297 FPS , and the 200 gr. bullet with a max. velocity of 3150 FPS . Also shown are the .224 Wby. Mag. and the .460 Wby. Mag. cartridges , but they use different powders . I presume that the velocities listed were from a 26" barrel , although the .340 Wby. Mag. data shows the 250 gr. Woodleigh bullet with a maximum velocity of 2986 FPS , where I actually chronographed velocity in 2 different Weatherby Mark V rifles . 3090 FPS average in rifle #1 (my brother's Weatherby Custom Shop with 26" Kreiger cut-rifled barrel) and 3040 FPS average in rifle #2 , my .340 Wby. Mag. rifle with 26" Douglas Premium XX stainless barrel . My brother's Custom Shop rifle is a thin contour barrel mounted in a #3 grade Walnut stock with upward pressure point under barrel at fore end of stock , and it will shoot 3 bullets through the same hole at 100 yards . It is the most accurate "Magnum Class Cartridge" rifle that I have ever shot , or seen . In my experience using the MRP powder , I have found it to be relatively stable in different temperature changes . Now , if you can find the NORMA MRP powder ??? DMP25-06 [/QUOTE]
