whats it take to swage a paper patched bullet?

Cast Boolits - Dedicated To The World Of Cast Bullets!

I am curious what it takes to swage a bullet from soft or low ration tin/lead alloy? I am getting into BPCR shooting and trying to be as traditional as possible. I am a tool and die maker so I have some background. I would like to make a bullet with a postell style nose .442 dia to be patched to .449-.450 dia. In the wieght range of 530 grains to 550 grains.
I have an lyman oarnge crusher press that could be dedicated to this project. Dies needed, number of steps to finished bullet, core molds or wire, ect ect. I have read very little about this but am interested in it for several reasons. The main one is I have Multiple Schlrocis and casting with the heavy metals seems to aggrivate it. Another reason (I think) is that these bullets may be more consistent than cast bullets? ?????? I just dont know enough to make an informed deccision here.
Again Thanks for all the help and information.
Oh these bullets will be used in a pendersoli Sharps in 45-70 and a C sharps arms Hepburn in 45-90 so one bullet should do duty in both nicely. Im only seating into the case .157 with the loads using BACO swaged 500 grn .442 dia pure lead bullets. with good accuracy . Another reason Im looking to make an informed decission on swaging.
Be sure to check in on the Black Powder Paper Patching section -- if you want to be really traditional, you'd probably be casting your cores and sizing to final dimension before wrapping the patches, as opposed to swaging, though commercial paper patch ammunition most likely did use swaged bullets by 1890 or so (maybe earlier). Casting is certainly a simpler, minimum-operations method (compared to casting cores for swaging) of getting to maximum accuracy with paper patched bullets, and casting is capable of delivering all the accuracy you can use (long range BPCR competition shooters shoot paper patched cast, almost exlusively).

If casting seems to aggravate your MS symptoms, you should check with your physician to see if you can determine which of many substances involved might cause this; generally, casting with reasonable care won't expose you to enough lead to worry about (many long time casters have body lead levels below average), but chemicals in flux smoke, cleaners and lubricants used on the molds, etc. are much more volatile and easily absorbed.

Country Gent: Check with Richard Corbin. He has a swaging die set to make a 0.442 paper patch bullet with a "Money Bullet" nose profile and a cup base for $185 on clearance. To use it you'll have to get the Walnut Hill press for $449. I have both the press and the dies and it makes a beautiful bullet. I use 0.385 wire that you can get from Richard too. It can be adjusted to make any weight desired within reason.
