Hi fellas, would any of you know what charge i could use to fireform .30-.30 brass in my .38-55? I currently have H4198, xmr2015, h414 and h322. Would any of these powders work??
Win94, H4198 in a near (95%) maximum load with any 30 caliber bullet should take your 30-30 to the new chamber just fine. My gunsmith introduced me to this method to form 358 from 308 because I was having trouble with uneven necks using the oversize expander. It works slick!
If i am reading your post correct, you want me to shoot a .30 caliber bullet in my .38-55 barrel which is .376"?? Won't i be bouncing the bullet all over in my barrel??
Isn't there a process to use about 10gn of a fast pistol powder, 700X, then fill the cases with cereal and a plug of wax on top, then shoot. The cereal will pack tight and press the case out to the chamber dimensions with haveing high pressures.

Have done it for years, with 10 grains of unquie and cream of weat filler, stand out side and point bbl up and fire,most i have to do after is a little trim work, but it will end up short, best bet is go to Star line and buy thier brass

Ken Waters in his Pet Loads book writes: "We can make our own substitutes from either 30-30 or 32 special brass with the use of a step expander die from RCBS or with a small charge of pistol powder, I use 15 grains of Bullseye on top of which I place a wad of twisted paper towel and fire into the air. This fireforms the case out to the 38-55 profile but note carefully-NO bullet may be loaded over this charge!! The resulting case is .070 shorter than a regular 38-55 case but will do no harm and delay the need for trimming."
I just bought 100 pcs of new Win. Brass from Midway, This should keep my Contender Bbl. shooting for along time.
