shock wave grain weight
I prefer the 200gr over 150 gr pyrodex pellets. Great ballistic coefficient,flat trajectory,capable out to 250yds. The 250 gr is almost identical with little more arc to the trajectory. Generally easier to find in the stores. If you can get the newer bonded shockwave that is even better. If you are shooting whitetails these two are more than enough. If you are looking at mulies,elk,moose etc. then you might want to move up to the 300 and 350. Any of them really do hit like the Hammer of Thor!! Finally the light is being shed on the powerbelt mumbo-jumbo.
