I would like nothing more than to use a traditional lead bullet like a wadcutter and a roll crimp, but Ruger seems to make all .327's with .314 throats and I can only find lead bullets are either .312 or .313, so they're undersize going, there's gas blow by, and the bore gets leaded.If its working and you are happy,enjoy.
I'll just toss this out there as my general understanding of crimp types. Its OK to disagree.
A taper crimp is best for semi-autos as it primarily resists the bullet being seated deeper during the feeding cycle.Its also better than a roll crimp for headspacing on the case mouth.
A revolver needs exactly the opposite from a crimp. It needs for the bullet to not be pulled forward during heavy recoil.
And because of the "freebore" of the cylinder throat,the cylinder gap,and then the forcing cone before the rifling engraves to provide resistance,its difficult for the powder to get up to minimum pressure for good ignition.
The function of a good roll crimp into a crimp groove is to provide resitance to the bullet leaving the cartridge case till the pressure elevates a bit more.
IMO,selecting roll crimp vs taper crimp is usually as simple as : Revolver or semi auto?
Of course,to roll crimp a crimp groove or shoulder is required to give the crimp a place to go. Your 32 Auto bullets likely do not have a crimp groove,so taper crimp may be the only option.
In my Ruger Single Six 32 H+R,a great plinker ammo is the Fiochi 32 S+W Long wadcutter load. The bullet is seated flush with the case,and roll crimped. They shoot good for me.Quite mild
There is one hollow base wadcutter .312 bullet I know of and that may be able to seal against the throat. For now tho, these .32 ACP bullets are working and they're half the price of those wadcutters.
As for the crimp, yes, I feel given that these bullets are meant for a taper crimp that that's the proper style to use. I think I tried a very light roll crimp by seating the bullet to where the case mouth was past the ogive, but it didn't look or feel right.
Speaking of the crimp, my uncle reloads and tells me that he never crimps any of his ammo because it reduces accuracy and because case lengths have to be identical. I'm not looking for utmost accuracy, but I don't want to shoot uncrimped bullets in revolvers. Does crimping a bullet reduce accuracy under these circumstances?
