Can a Ruger SA .32 H&R Magnum also shoot .327 Federal Magnum?

    I saw a pair of polished, stainless, Ruger, birds head, SA revolvers at my favorite, local gunshop. They are both .32 H&R Magnum caliber. They have black plastic? grip panels which are a bit bulky for my liking but I think a thinner pair of wood grips would fit my hands better. Anyway, I was wondering if .327 Federal Magnum cartridges would also fit and would they be safe to use? I know next to nothing about the .32 calibers but I am intreged by the smaller SA Ruger frame with a lot more umph than 22LR/22WMRF.

    10mm, when you care enough to send the very best.

    I don't think so. The 327 is a lengthened version of the 32 mag, so the cases should be too long for your cylinder.

    I have "heard" that the rugers are strong enough to handle the pressures generated by the .327 if you have your chambers lengthened to chamber it. And you can still shoot the .32 H&R mag in them.

    Any input from anybody else?

    There's been a few I've seen that were rechambered for the .327 Federal. It is do-able.

    The factory cylinder is a little too short for the 327FM. A long-bodied cylinder is needed, as the 327FM is .125" longer than the H&R version.

    I really like the 327FM. Planning on building a 327 Single Six at some point.

    The cylinder also needs to be heat treated to a higher strength because the 327 develops more than twice the pressure of the 32 Magnum. There have been some conversions done on a custom basis, not cheap. I wanted a Single Action revolver in 327 but do not want a Ruger NMBH; so I ordered a USFA 5 1/2" convertible in 327/32-20. Back ordered several months and comparatively expensive. I'm eagerly anticipating!!! In the mean time I have a Charter Arms Target Patriot in 327 to play with. Great cartridge!!!!!!!!

    No, a factory .32 cannot fire .327.

    The .32 Single Six can be converted to a .327 with a new six-shot cylinder but it needs to be longer and the barrel shank shortened for sufficient length for all bullet weights.

    Your grips are a very tough material known as micarta. Black linen micarta in your case. Not plastic.

    I just got back from the gun shop where we measured the cylinder and then a cartridge, the cylinder is approx. 1-3/8" long and the .327 Fed. cartridge is approx. 1-1/2" long so it wouldn't work but Ruger could eventually build one for the .327 Fed. Magnum/32-20 if they saw a market for it.

    That 32 H&R will shoot just as good as the 327......maybe even better. I like both though and that's a nice looking Birdshead! gene

    No, not without altering the cylinder as earlier said. (intrigued)

    Ruger already chambers the SP101, GP100, and NMBH in 327. I will be very surprised if they tool up to chamber it in the small frame Single Six. I would hope they do, as I think the two big revolvers are too large for a 32 caliber chambering and they don't offer a 4 or 5" barrel with fully adjustable sights in the SP101.

    Can a gun chambered in 327 shoot 32 h&r?

    Yes, the 327 guns will shoot the 32 H&R.

    One can simply load up the performance of the 32 H&R also in guns that will handle it...like the Rugers. That was being done just after the 32 H&R's introduction. The lengthened case of the 327 was done for the same reason as the 357 and 44 Magnums - to prevent chambering in guns not designed for those pressures.

    Flightsimmer,if you reload,follow the data on the Hodgen web site for L'il Gun powder. It safely improves the 32 mag. I use their data in my Ruger 32's and am pleased. Byron
