I've played with this oddball for around four years now with fair success.
I use a standard Lee die setup (my sizing die's marked as a .32-20)....with the single modification of installing a cylindrical insert under the seating plug in order to get the bullet down into the case........works like a charm. Crimping is no problem, just adjust the die to the point you achieve the amount of it you desire.....it won't quite look like the pictured factory stuff, but it is a waisted crimp not too awfully different.
Bullets I use are mostly cast Lee 100 gr. RN's sized to .308 and lubed with Javelina brand alox. I seat that bullet about a quarter inch into the case over 3.0 grains of Bullesye and then dribble a coating of Lee's liquid alox on top (don't know if it REALLY makes any difference, but my gun has a rough bore so the extra lube's gotta help).
That load, in my gun, will cut ragged hole groups at ten yards.
Brass I use is mostly Graf's (Starline) with a couple of twenty round boxes of Bertram I picked up when I first bought the piece...........Should you use the latter I'd strongly caution you to avoid full length sizing as that stuff is without doubt the most brittle brass I have ever seen......full length it and you WILL loose 80% of your cases. (don't ask how I found that out!)...
Bottom line is that its a fun project and it can produce some surprising results..........
Forgot to mention that a friend gave me 1m of .32 commercially cast bullets.....swc's.....at .312 dia.....they're usable, but I see utterly no difference in performance, plus they are a bit tougher to seat.
As an aside, that batch of Graf's brass I got is NOT sufficiently long enough to afford you a gas seal.....I called 'em on it and they knew it was 50m too short..........frankly I see no difference for my purposes but if you intend to supress the thing it MIGHT have some slight consequence.
Hope this helps.
