I have data. 180 grain jacketed and 171 gr cast with gas check only though.
Midway has Quality Cartridge brass. Not cheap though. $67.99 per 50. They also list dies. Redding at $67.99. RCBS dies are rediculously expemsive and have a 90 day plus waiting time.
The trick will be finding a reliable supply of bullets. It uses .351" RN jacketed bullets or .352" cast with gas checks. Old Western Scrounger currently carries ammo and bullets. The ammo(brass made out of .357 Maximums. They use an RCBS #6 shell holder.) is $49.95 per 20 for 170 grain plated bullets. 180 grain jacketed RN's runs $12.95 per 100.
