.327 rifle?

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.........

As for about a 327 rifle I am haven a gunsmith maken one for me .going to make it work for the same ammo as my ruger black hawk .i aks him to be able to do that and still working in it he is .Finding a barrle was the biggest thing now he got that is in and the barrel need to be custom made.

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.

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