.327 rifle?


Registered Users do not see the above ad.


Does anyone have a rifle chambered for the .327? If so, how does it perform?

I have a single-shot chambered for the 32 H&R Magnum. It is a fine small game round. I wonder if there is enough difference between the two from a long barrel to justify rechambering.

There's a *huge* difference between the two rounds, and with the right powders (h110 being a great example) you're going to see massive increases in velocity just between a .327 Fed Mag pistol and rifle. Between .32 H&R Mag and .327 Fed Mag rifles, I'm betting the difference would be staggering. Not like you'll suddenly have a .308 Win with a smaller case, but I'd bet it'd match or outperform the .30 Carbine. Remember that the .32 H&R is still fairly anemic in terms of pressures, topping out at about 21,000 PSI. .327 Fed Mag tops out at about 45,000 PSI. So, the .327 Fed Mag is going to give you more powder, burning for the same length of time, but accelerating the bullet faster due to the higher pressure. So, at a guess? Take your .32 H&R rifle velocities and increase them by about a third.

Considering that, assuming you don't have some pencil thin chamber, rechambering your barrel for .327 Fed Mag will take your gunsmith about 20 minutes, I'd do it. After he gets the reamer, of course.

To my knowledge, nobody has chambered the .327 Fed Mag in a rifle as a production gun. Who made your single-shot .32 H&R?

Well said, I am going to have to agree 100% on this..........Seems like a very interesting little rifle;to be.........

Good job!

You would probably need to load your own to get the most out of the longer barrel. A slower burning powder would be in order.

With the hottest 327 FED factory ammo (Federal American Eagle 100gr SP) I get over 1700fps out of my 5.5" barrel blackhawk.

I shoot an unsized tumle lubed (JPW) HTWW cast lead plain base (SAECO 98 gr.) SWC bullet, 104 gr.

Velocity is 1200 fps from a 6 in revolver and 1550 from a 22 inch rifle.

I could probably get more velocity with a jacketed bullet or a gas checked lead one but this is my only .32 pistol bullet mold and I also use it for .32 S&W Long revolvers. The 32's are FUN guns to shoot.

Looking at Quickload I should be able to get about 2,000+ fps with a jacketed 115 grains and 2,100+ with a jacketed 100 grain.

The rifle is a rebored H&R originally in .22 Hornet.

BBTI - Ballistics by the Inch :: .327 Mag Results

The table gives muzzle velocities for barrels up to 18" with factory ammo. You would want to tinker with that, using slower burning powder to get higher velocities. I don't think you would want to go with a longer barrel. The round seems ideal for carbines.

I know of a few guys that have rechambered their 32 H&R Marlin 1894's in 327. They seem happy with the result.

A 100 grain cast bullet over Lil'Gun gets 1800 fps in my 20" barreled Marlin and 1300 in my 5.5" Single Six.

Yeah, but find one for less than $1500!

I don't know that a barrel longer than 18" would be pointless. I have a Marlin 189FG (.41 Magnum) with a 20" barrel, and there's still light muzzle flash with Lilgun pushing a 210gr JHP, meaning I could do with another inch or two.

Yes, a .327 will have less powder capacity, but there's also less volume for the gases to fill from case head to muzzle.

I'd sell mine for $1499...

I get 1800-1900 fps with a 1912 Winchester Mod 92 in 32-20. You're right on a par with the old HV-92 loads for the 32-20

I don't actually know what the going rate is. They do seem to command a premium on gunbroker, as do all the Marlin Cowboy rifles do now.

I know it would take that to get me to part with mine

I paid $1100 and $1300 for two Browning 1886's in 45/70. Seems to me those Marlins are a wee bit overpriced.

I think it's just that they weren't produced in large numbers and a lot of people want them, now. I have a Marlin 1894FG (.41 mag) that I could probably get $1100 for, but I probably paid about half that for it, and not really that long ago, either. That one they'd produce for a year and then discontinue for two, it seemed.
