[QUOTE="budlight, post: 1973509, member: 2939"] hodgdon online reloading gives loads for a 147 gr 24 inch barrel going 835 mps with Hybird 100V and Superformance Your problem is the short barrel. Energy is of course mass X velocity. It has been my observation that for any rifle the foot pounds of energy at the muzzle is consistent from the lightest to the heaviest bullet when loaded to near max with the best powder for each weight. So a 6.5 CM 100 grain has the same foot pounds as the 156 probably out to 50 meters. It is only with distance that the heavier higher BC bullet can strike with higher foot pounds of energy. with a 20 inch barrel you want the lighter bullet with faster powder to create the highest striking power. Slowest powders only work with heavy for caliber pills in the longer barrels. So I use the above two powders in all my 6mm .257 .260 .277 rounds [/QUOTE]
