Hi. I own a Taurus M44 44mag with a 4 inch ported barrel. I do not do handload and I am not in a position to get rid of it and get a Colt or Ruger or a Dan Wesson....I know that I should have purchased a higher quality from the beginning, but didn't. So I am headed to Kodiak Island AK in October and want to find a factory load for that gun to use for bear protection. What can I use? How hot and large can I get away with in that gun?I purchased some low recoil buffalo bore loaded with 255 grain keiths....is that enough? Can I shoot heavier buffalo bores loaded with 305 grains (not the +p stuff)?Any help and suggestions are greatly appreciated!
