Thanks for the load info. I'll likely be shooting 330gr Money bullets to start, though I'm thinking something in the 275-300gr range may be needed. 

When I talk about the 'old dead guys' that I would like to emulate, I'm talking about those before the turn of the 19th century. I'll likely shoot BP, but may try a duplex load with 4-5gr of Unique under 35gr of BP or something similar. Think the ODGs started using duplex loads prior to 1900. Of particular interest to me is lengthening the recoil with the slower burning BP. I find shooting off the bench to be about the worst position for me, recoil-wise.

.303 Brit -to- 38-40 on left and 30-40 Gov't -to- 38-50 on the right. 
One stroke resize thru a die that Chris Christensen made up for me (thank you, again, Chris). Makes life easy.
38-40 case will get chucked and parted-off from 2.175" to 1.80 and then trimmed to final length in the Forster.
38-50 cases come out almost perfect and only the occasional case requires trimming after firing. Then all cases will get their annual trip thru the annealing flame.

Am hoping to get enough primers to resume load testing this next spring. I have a 245gr & 265gr GG bullet and a 300gr PP bullet. Initial testing with 44gr of 2F were positive, but brass needs some additional work. Will be reaming the case mouths.

I am having the same problem of sorts. Picked up an all original Hepburn in 40-2 1/2 (40-70 ST) and the bore is toast. Wanted to keep it original but can't if I want any reasonable accuracy out of it. I am looking at a rebore to 44 cal or liner and keep the same chamber. There were some chambered in 44 cal but that would mean rebore cost more expensive dies and brass and a bullet mold. And then the cal marking on the barrel wouldn't be right. Decisions decisions...
