Posted By: Ghostrider WTB .300 Rook ammunition. - 02/01/23 10:46 AM
I recently purchased a nice H&H rook rifle and would like to be able to shoot it. I would like to purchase some .295 H&H ( .300 rook ) ammunition. Pease PM me if you know where I might purchase some. My understanding is there was ammunition being made up until a few years ago.

Not loaded ammo, but Buffalo Arms has brass, bullets, bullet mold and dies. I just ordered and received this stuff for a 300 Rook I bought a couple months ago. I have started loads with 7.5 grains of 4227 and 5.7 grains of 2400.

Use .301” bullets. It is worth acquiring a die to size down .308/.312” ready cast bullets of 80 to 90 grains made for .32 S&W or .32 ACP.

As to “a few years” ago Kynoch pulled the plug on all centre-fire rounds in 1972. I doubt if they had actually made a batch in this calibre since the early 1960’s.

If you can find any factory rounds in boxes marked Non-Rusting or Non Corrosive they take the No. 69 Berdan primer.

I have found that Pre-1939 cases take a slightly larger primer so No. 69 primers look as if they should fit but then fall out.

Bertram make Boxer primed cases.

I shoot the bullet from the Buffalo mould sized .301 with 3.3 grains of AA 5. I see that Larry Potterfield (Midway) is using 4.0 grains of Unique in his video.

I appreciate this information. I hope to shoot this rifle next week.

Ghostrider,

Nice rifle and outfit. Is one of the spare barrels a shot barrel?

To fit the case you probably need a pre-1939 50 round box (no dividers, rounds boxed nose to tail like they used to box .22 rimfire).

The post war boxes with dividers and rounds all base up are a bit bigger.

Thank you for the information on the box.
Yes one barrel is a 410 converted from a 300 Rook barrel. Very well done.
Posted By: Parabola Re: WTB .300 Rook ammunition. - 02/02/23 02:36 PM
Thanks, what calibre is the third barrel?
Posted By: Ghostrider Re: WTB .300 Rook ammunition. - 02/02/23 06:11 PM
There is the 300 Rook, a 25-20 Single shot and the converted 410.
Posted By: Parabola Re: WTB .300 Rook ammunition. - 02/02/23 07:47 PM
Very Nice!

Still looking for ammunition as well as a set of 25-20 SS reloading dies.
Posted By: Remington40x Re: WTB .300 Rook ammunition. - 02/04/23 08:08 PM
Have you tried the ASSRA web site for the .25-20 SS dies? There are a number of guys on that site who shoot the cartridge.
Posted By: HalfaDouble Re: WTB .300 Rook ammunition. - 02/04/23 08:27 PM
I just use 25-20 Win dies for my 25-20 SS and an RCBS #10 shellholder as many on the ASSRA site do. Only need to neck size and the seating die works fine. Check the twist on your barrel and use a matching bullet weight.

Thank you guys for the information.

There is a 2 die set of rcbs 25-20ss on ebay currently as an auction, not cheap but there is one bid on them.
