.32-40 Requirements? (Read 17767 times)

	Since .32-40 brass is virtually non-existent, what does one need to shoot a rifle of this caliber (breech seated; smokeless powder)? I've been able to determine that the Starline .38-55 (long) brass would be a good starting point. Dies? Bullet molds (base pour/nose pour)? Thanks.

	Slightly short 32-40 brass can be made from 30-30. 38-55 would be better, anneal the cases and use some Imperial Sizing Wax (sparingly), trim to length and you are good to go. Bullet choice depends of several factors such are bore diameter and twist. A 1-16 twist will not usually stabilize a 200 gr bullet. My 14 twist Green Mountain barrel likes the Hoch Darr style bullet sold by CPA. About 14.2 gr of 300MP and Remington std primers works well for me. Your mileage will vary. Plenty of advise available here. Jack

	People who think they know everything are a great annoyance to those of us who do.

	Ed, the diameter of your bore and twist will determine the best mold/design. If yours is close to mine (1:14 .3205) I'll give you some different ones to try when you take the plunge.

	The short Winchester 2.080 will grow if you use a little Inperial sizing die wax and resize it in 3 or 4 passes. 40 Rod

	Thanks for those pic's. Good illustration of 'the possible'. Is that 2.08" or 2.125" long 38-55 starting brass?

	Ol Deuce, I note that in the pics, you have slight longitudinal wrinkles in the reformed 30-30 and 38-55 brass. Have you tried forming the 32-40 from the long Starline 38-55 brass? Have you tried annealing the cases before forming to 32-40? beltfed/arnie

Glenn, I used 2.08" brass and from what I remember, the length came out perfect. I could dig them out and measure them if it would be useful to you. Just let me know. Chris.

	Some deformities created when sizing .32 Win. Spl. or .38-55 down to .32-40 are from too much lube. It gets trapped and creates a hydraulic pocket of lube that indents the case. Less lube, and maybe gradually doing 2-3 hits instead of one complete hit of the press stroke will eliminate the dents. I've used .32 Win. Spl. for years, and spray lube to size them. I find spray lube works great, and is so thin it rarely creates dents in the case.

	I tried a few different sizing lubes and ended with Lee. Anneal - lube - partial resize - lube - partial resize - lube - final pass. You'll get it easy in three, sometimes two with minimal loss.

I was using Hornady case lube and now have moved to Imperial which does a much better Job!! Randy
