I recently acquired a Ruger SP101 in .327 Federal Magnum. I'm looking for carry ammo, and can't decide between the Speer Gold Dot 100 grain @ 1500 fps/500 ft. pounds of M.E. vs. the 115 grain @ 1380 fps/486 ft. pounds of M.E. Anyone tried both and have an opinion or even just an opinion? I know the standard answer of "try both and see which my gun shoots best", but curious what you may think. At the moment I'm leaning towards the 100 grain.
