[QUOTE="Lefty7mmstw, post: 1914587, member: 48043"] if I were to take your question literally you would actually be asking how big of a hole in the end of the barrel do I need to make my pipsqueak little case make more energy... I run a 270, a 30-06 and a whelen... All burn around 55 grains of single base powder (IMR single base powder all has the same energy per grain content; the difference is in grain size and coating) I do prefer double base in the whelen (rl15) but it eats single base just fine too so the comparison holds my 270 (130 grain pill-3050 fps) develops 2686 ft# of muzzle energy my 30-06 (165 grain pill-2850 fps) develops 2976 ft# of muzzle energy my 35 Whelen (220 grain pill-2700 fps) develops 3562 ft# of muzzle energy [/QUOTE]
