The 295 Rook
      #378449 - 07/08/23 05:31 AM

While not exactly a dangerous game cartridge (unless you have a death wish), the 295 Rook is an interesting little hunting cartridge. The loads that I have seen (5 gr Unique pushing an 80 gr cast bullet) seem hot with velocity in the 1400+ fps range as opposed to the 1100fps.

The bullets shoot high at 25 yds. I ran out of time (and ammo) yesterday and didn't try then at 50 yds so I don't know how high/low the bullets were hitting at that range.

Does anyone shoot the .295 (.300) rook and if so, what loads do you find gives the best accuracy.

BTW, the bullets I use are from Buffalo Arms. I thought about Neilsen air gyn slugs but those do not have a gree=ase grove and I would be concerned about leading the bore.

A bit more time & ammo 85lc & you'll get there!
Sounds like you had a lot of fun though!

Hi Roy,

I feel your load is far too strong.

Here in England we have lots of knowledge of how to load the Rook rifle cartridges, especially since the pistol ban in 1996. My data from September 2000 gives a load of 3.0 grains of Vihtavuori N320 powder (similar to Red Dot), with velocities of 1081, 1080, 1076, 1106 and 1107. Bullet was an 80 grain soft lead bullet cast locally.

remember that the bores sizes vary a lot! My H&H had a bore of 0.292", whilst other makers were often 0.300". H&H deliberately kept their bores tight to increase pressure and so accuracy.

I never like Unique anyway, but I believe the new variety burns better?

Good morning, Allan,

That is great info. Your load gives the exact velocity that I am looking for. It seems very consistant (ie, little variance) velocity that should provide great accuracy.

The burn rate of N320 is a little faster than Unique and slower than Trail Boss.

I will buy a can of N320 to use.

The 5 gr load was from the Greenwood book on rook rifles and, considering teh original load was 10 gr of FFFg powder, reasonably seemed too hign. Looking at my notes, the actual load I used was 4.5 gr of Unique (10% less than Greenwood recommended) and that generated 1400+ fps velocity in my rifle.

BTW, I was also given a load of 3.0 gr Bullseye which is also way too strong of a load.

I am trying to get a good load so as to shoot my 295 rook in a match at Oakridge.
