I've got conversion cylinders for my ROA and Pietta 12-inch 58 Rem and like them as an occasional alternative to powder. I am thinking of getting a 38 spl cylinder for my Uberti 36 cal 1858 Rem and hear that hollow-base bullets are the way to go to overcome the cylinder/bore mismatch that wreaks havoc on accuracy. Using black powder, I usually use a .380 home-cast ball and get good accuracy. The .357 bullet from the 38 spl is simply too small for a good fit in the barrel to get the rifling to work. I have a hollow-base 38 spl mold and intend to reload. My question is: have any of you used hollow-base 38 spl bullets in your 36 revolver and what was the result in terms of accuracy? I really hope they do in fact "ballon" enough to engage the rifling, because I don't want to have the barrel re-lined. Also, if you're a reloader of 38 spl for a 36 conversion, what's your favorite load? Thanks for info.
