Team.
Our club's annual auction was at the weekend and I picked up a WH Tisdall Rook Rifle manufactured in Birmingham UK in .380 cal. It is a rolling block action and quite unique (some might say ugly....[smilie=1:).
There were a pair of .380's in the auction and the other piece was a Martini action that was just lovely. It went for more than I was prepared to spend on a "may or may not be shootable" rifle. Fortunately the rifle I bought was 4 lots further on and so I bought the ugly sister for a lot less.
The roller has a 27 1/2 inch barrel with 3 leaf express sights (tight and in good condition) with a bead up front.

Aciton is TIGHT and though I have worked the trigger the pull is still very heavy so I will have to try and fabricate another spring.

Bore is very shootable though cares its share of pitting for a 140 year old rifle. Rifling is crisp and well defined however. Best I can measure the groove is .369 which is kinda tight for a .380 Rook but kinda loose for a .360 Rook. I have trimmed up some .38 Special brass and at .945 they chamber and eject reliably though this case length is a little short of what 'Cartridges of the World' list for the .380 also. HHHMMM. Following is .38Sp, .380 and .38 S&W for comparison.

I have ordered a .377-124 heel bullet mould from Jim at CBE as his mould is a copy of the original bullet.

Thus far I have been shooting the rifle with a .395 round ball run into my .375 lubesizer die to create a .375 ball(et), bullet with belt. The ball(et) is seated in the case mouth just enough for a friction hold.

These ball(et)s at 94gr have been loaded over 4.5gr Unique and generate just shy of 1200fps and printed this at 25m.

The four shots are in under an inch and the low round was from a tight chambering round where I had seated the ball a bit firm and created a belt of lead larger than the OD of the cartridge. Have also been shooting the same ball(et) over a BP load and getting similar accuracy and velocity. Both loads have an unlubed bullet and a grease cookie over the powder. I start with a lubed bore and get no leading at all.
Will post a photo of the rifle itself this evening and keep you all updated on progress.
