I think I am correct on this but need some advice from someone more experienced than I with the Lyman 310 dies . . .
I'm adding 32-20 WCF to my reloading line up and am trying to get a set of dies put together for that - even if mis-matched and cobbled - as long as they will work.
I have come by a 32-20 FL sizing die with an expander stem and de-capping pin - so that should take care of the "sizing", "de-priming" and the "mouth expanding" - I may de-prime with a 310 universal de-primng die and just use the new die without the de-capping pin.
So . . . what I need is a "seating die" that will work. Looking at the chart, it shows a . . .
#29 32-20 WCF (+ 30 Carb)
So I am assuming that some of those two cartridge 310 dies are interchangeable?
I don't have my reloading manuals handy but looking at the cartridge specs on Wikipedia I find . . .
Bullet Dia. .308 (Carbine) .312 (32 WCF)
Neck Dia. .331 (Carbine) .327 (32 WCF)
Base Dia. .354 (Carbine) .354 (32 WCF)
Rim Dia. .360 (Carbine) .408 (32 WCF)
Case Length 1.290 (Carbine) 1.315 (32 WCF)
COAL 1.650 (Carbine) 1.592 (32 WCF)
The differences mainly being .004 larger bullet diameter in the 32 WCF, rim diameter which shouldn't affect anything as far as a seating die, case lengths but the COAL is close enough that by adjusting the seating stem should work fine?
Am I thinking correctly on this that a seating 310 seating die body and stem for the 30 Carbine will work just fine on the 32-20?
I'm also thinking that if I can find an expander die body for the 30 carbine and an expander stem in say .313 or .314 that it should work as well for the cast bullets I want to use which will probably be around that size?
Thanks for any input - greatly appreciated!
