Looking for advice on putting together this toy. I have pretty much decided on a Savage target action on a 7 Fingers pistol stock. Had thought about a 17 Fireball but brass is hard to come by and reforming is a lot of work. I do have about 300 pieces of 221 Fireball brass for my rifle but I didn't want to chamber the pistol in the same caliber. What I'm looking for is low powder usage, light recoil, long brass life and the ability to shoot 200 yards with one MOA or better. I would like to stay with the 221 FB brass, so if anyone has any suggestions for cartridge and barrel length I'd appreciate it. Thanks
