In the interest of being more accuracy minded I followed the examples set here and I slugged my first revolver this morning.
I picked up a beautiful older (maybe 80's) Ruger Blackhawk in 357 Magnum. With a nice short barrel this is intended to be a packing around gun for camping and fishing.
So I slugged a couple of the chambers and they measure .3595". Do I need to do all of them or can I just assume for the rest?
I slugged the barrel and I not sure how best to measure it. I have a nicely engraved round ball and a nice Starret veneer caliper as well as a nice Lyman Micrometer. What's the best way to measure the engraved slug?
