.300 Sherwood or .300 Extra Long?

[richhodg66]

The cartridge the Rook Rifles were chambered for. I don't know much about it, a quick look says there's custom brass available, but can it be formed from anything else?

The best practical solution for these antique British rook rifles is simply to reline them and chamber for .32 S&W Long or the .38 S&W so you can use common and plentiful brass and bullets. If the original bore is in nice shape, just rechamber to .32 S&W Long or .32 Long Colt and load bullets to fit the origin of rifling. I would cast your chamber and the bore just ahead of the origin of rifling to determine its original dimensions before doing anything else. Many of the .295/.297/.300 rook rifles were .300" groove diameter and shoot OK with .32 Long Colt as-is. The .310 Greener was .320 groove diameter and uses a heeled bullet.

Interesting. I'm intrigued with the whole "Rook Rifle" concept. Just got to wondering how hard it would be to keep one shooting if original.

A .360 No.5 or .380 Rook with good bore will shoot .38 Special HBWCs accurately with simple rechambering. The .295/.297/.300 Rook rifles will work with .32 Long Colt, but "jump" or excess free bullet travel is caused by the longer .300 Sherwood chamber, and bores of many of the black powder era rifles are in poor condition, so relining is more viable. The antique black powder actions should not be used with loads exceeding about 16,000 psi.

Would one of the longer .32s, H&R Mag or .327 Federal cases not fix this?

You might be able to use .25-20 Single Shot cases for this by blowing them out straight. If you are lucky, you might be able to find a stash of Jamison .25-20 Basic cases, which were straight-walled and could be necked down to the .25-20 or the .22 wildcats based on the case.

I had a friend who glommed onto a bunch of .32 Long Rifle cases I’d made from .25-20 SS for his rook rifle in .300 Rook. (It was some kind of weird British bolt action single shot; I forget the name.) I never saw him shoot the loaded rounds but he never complained that they didn’t work, either.

I use the neck-cracked .25-20s by cutting them to .32 Long chamber length (eliminating the split necks in the process) but the .300 Rook chamber should handle the full-length shell, and the case mouth is the right diameter for the .299” diameter hollow-base inside lubed boolit.

.32 H&R Magnum case is 1.075" with .375 rim diameter and .337 base diameter. The .327 is 1.20" long with same rim and base diameters.

.32 Long Colt is 0.92" with .374 rim and .318 base diameter.

Interesting. Probably right, relining or a new barrel would be easier than getting one in the original caliber shooting.

If they are close enough to the .32 LC you can probably get a good start with these, the brass is about .93", 32 XL is probably a better OAL for your project but you would have to do the work yourself from .327 parent brass or track down some 25/20SS as suggested. A lot of work done in the last 10 years has been posted elsewhere on this site to make .32RF cartridges that will give insights into generating brass, bullets, and loads.

I, for one will stand up and say don't use 32 S&W reamers in old guns if they have anything more than minimal value. You can make them shoot just fine, some tinkering required.

I think Bertram still make the cases.
If you load it like a shutzen rifle with a plugged case or even a stick and breach seat you will not be working the brass and they should last you years.
You could just carry a few bullets in a tin and loaded cases when out shooting.
Not that hard to load or take up much time when shooting wabbits n things.
Gotta keep those precious cases in good nick.

If shooting fixed and want to blast away well….probably better off with a more common case.

What ever rocks your boat.

Just a thought.

Here is some brass available - and as another poster mentioned, should last a long time! And the website is dated, but still has great information!!!
It would be a shame if all of these " obsolete" cartridges die off completely!!
