Sometimes plans change. I was looking for something else in my reloading shed junk shed, and came across a box of .310, 165gr flat point bullets purchased eons ago. Which is a good thing, because the .38-55 bullets I have are .380 diameter, cases are Winchester, and just like the interwebs warned me might happen, that combination won't chamber in my rifle. Needs a smaller bullet, or thinner case(Starline), or it might work with resized 30-30 cases. Fortunately, I only loaded one round to check the fit.
