Reloading gives a lot of options with bullets.
Not as much as you'd think. Casting your own bullet you would, but the effective bullet weight for the .32's it seems is anything 90 grains or more. When I shoot anything under 90 grains (the 85 grain JHP's being an exception) the accuracy is dreadful and that's not limited to just .327 either.
So, at 90 grains or more there's a few jacketed bullet options, two are Hornady XTP's, two 100 grain Rainers, and a 90 grain Sierra soft hollow point. As for lead, there's a couple 94-95 grain flat nose options that I like, the 100 grain wadcutter is a standard bullet for .32, several 115 grain flat nose that also shoot really well, and a few 120 to 125 grain options from Mattsbullets.
That's it. One of my original goals with the .32 centerfire was an ultra light, subsonic load that mimicked .22 LR as much as possible, but the issue I ran in to was that once you went below 90 grains, the accuracy went to crap. The only light load I haven't tried is a 50-ish grain round ball in the Henry rifle, mainly because I know it won't feed and I'm afraid the ball will get shoved deeper into the case in the tube magazine as there's no crimp groove. I've tried it in a revolver and I loaded it too light to the point I got a squib. Nice thing about that was round balls are really easy to punch out of the bore.
So the options are mostly 90 to 120 grains. For a revolver, I think 100 grains is just fine, for the rifle I would go as heavy as possible with the projectile. Trajectory will suffer, but the .32 seems to prefer heavy bullets.
The issue with the lead bullets tho is Ruger makes all their .327 revolvers to be used with jacketed bullets and the throats of the cylinders are big, very big. Leading will occur with enough shooting. So, unless you like crap accuracy and cleaning out lead from a bore, you're stuck with jacketed bullets in which there are only 5 options.
This is the problem with .327, I can't speak to .32 Mag and more modern .32 S&W Long revolvers as I only have a Heritage .32 Mag and an H&R top break .32 Long to compare. In a rifle, there's no issues and that's the main reason I see .327 and the shorter .32 calibers future in rifles, be them single shots, levers, bolt action, or maybe semi-automatics if Ruger would ever make an updated Model 44 design for more than just the .44 caliber.
The market for .32 is too small that the industry will not go out of their way to offer more bullet options, factory ammo options, or guns and because the market is so small people who are not interested in .32 for the reasons of the lack of industry support will not buy .32 as a result. About the only way out I see is if more women get into carrying guns for self defense and choose the .32 caliber, namely the LCR.
I was glad to see Charter offering a 7 shot .32 Mag they're dubbing "the Professional" because I hope to see that trend continue. If S&W and Taurus and/or even Rock Island would get into making .32 snub revolvers, that would only be beneficial in getting the .32 caliber out there and more popular. Hell, even NAA could get in on the action and bump up the size of their mini revolvers to fit a few rounds of .32 S&W Long would be a help.
More rifles in .327 would be great too. Why Henry beat Ruger to making a rifle in .327, I do not know. Ruger could put this in the American (along with .357 and .44 Mag) and with a sub $400 price tag never be able to keep up with demand. I wrote to the CEO last week about bringing the Model 44 back in a variety of calibers, but with an updated design (I'm hung up on having one with two full length mag tubes like the KSG has so the total capacity would be something around 14+1) and I haven't heard back from him, nor anyone else with the company
When I wrote to Anthony Imperato of Henry about making a .327 rifle, I got a response from him the very next day confirming it was already in the works. I'm just led to believe that Ruger doesn't give a crap about the .327 anymore. They've offered it in all the guns they wish to make it in, they haven't pressured the ammo manufacturer's to make more ammo for it,
The bottom line is even with reloading, it doesn't solve the issues the caliber has.
