Rimmed cartridges with a .530-.540 rim.... (Read 1843 times)

	I have a highwall chambered in 30-40 Krag and want to make another barrel for the action. I would like to use the existing extractor, so would like to know your thoughts/experience with cartridges with a rim diameter of .530-.540. I use fixed ammo that I reload - love to experiment in different bullet & powder combinations. I can pretty much fabricate any wildcat cartridge as long as a reamer is available for rental. Thoughts?

	Best case to work from outside of the 303/30-40 Krag is the 9.3x74R. 405 was also good when Hornady was making it. The 405 and the 9.3x74 open it up to most any wildcat that has been made on the .30-06 case. For instance, I chamber for a .338 caliber using those cases by using my .338-06 reamer, and running it in extra deep. You can grind the reamer undersize behind the normal cartridge length so it can't cut, and it just cuts the back of the chamber straight, which works great. Cut the rim recess with the lathe. Reload the cartridge using .338-06 dies. Same with the 375-06 (375 Scovill). That one is easy to make dies by running a carbide chucking reamer into a 9.3x64 die to open up the neck to the right size. I made my die that way. 25-06, .270, 6.5-06, etc are all easily chambered this way. You can make them standard length or increase capacity by using the full length of the brass.

	40-72 uses a .408 groove diameter, 405 uses a .413 groove diameter. Same brass for both. Years ago I made a two barrel set for an 1895 in the two calibers mentioned. Test firing the 40-72 I thought it was a nice cartridge. When I fired the 405 I think I dislocated my shoulder. A 405 should not fit in a 40-72 chamber because of the larger bullet diameter.

	Thought we were talking about rim diameters, not groove diameters of barrels?

	It's not the rim diameter but the body diameter at the base that controls what rimmed cartridges will work with a common extractor.

I think it's both rim diameter, and body diameter. Of course that's excluding modern style rebated rim cartridges. In some cases I have to turn down the body of donor brass if the rim, and everything else is close as is. But if the rim isn't large enough, nothing else matters. Too large can be turned down a bit also, as long as it's not much too large.

	True. I was addressing the comment that the .30-06 family would be possible.

	Not sure what your intended use for the cartridge will be but I would think long and hard about and that are longer than the basic 30-40 Krag case. I have several 40-70 SS and 405 Winchester brass is very scarce to say the least while 30-40 Krag has made a comeback. This is not to say that 405 brass might become readily available again but my crystal ball is just too murky to see. My 30-40 Hiwall is so fun to shoot with lead bullets and does well with 180 grain Partitions for hunting that I have no desire to fit another barrel, but if I did it would be the 38-50. My $0.02 which after inflation is not worth much. Tom

	Base of .470 on 30-06 family cartridges, and .457 on on 30-40 is generally close enough to not be a problem with the extractor interchanging.
