My bore DIA is .3796.......... Besides a special order.....Is there a company that makes a die at .380 or .381? Thanks

Get the RCBS Cowboy dies, far as the larger bullets, the 38-55 is a tapered case, size it enough to hold the bullet without a tell tale bullet bulge when seated.

I have Lee dies made to use as 38-55 or .375 Winchester, had to raise the sizer over .100 to get it to work proper.

The RCBS dies come with two expander sizes.

I got lucky. My Lyman sizing die is marked .379 but every bullet I ever measured that was sized in it is .380 and that .380 size works in my 38-55. There are also folks that will open up a Lyman sizer by a few thousands but offhand I can't remember who they are.
