Rooks are fun little rifles. I have 2 in 295/300 rook and one that has been sleeved to 22 LR. The 295/300s push an 80 gr bullet at 1200 fps and is an effective small game load. It is also fun to reload. I have loaded these CF rifles down to 900 fps and up to 1450 fps with 1200 fps being thhe origianl load. The 22 is also very accurate though I have not shot that rifle as much as the centerfire rifles.
