Reeder Custom Guns - Ballistics

Can the .257 Raptor be chambered in a revolver? I have two of your books, The Complete Reloading Manual, and Hunting Handguns and Their Cartridges. While researching ballistics of your proprietary cartridges I noticed your 240 Banshee out performed the 250 Banshee, and the 256 GNR in velocity with the same grain bullets, or close to. Is this correct? Then, when you created the 256 GNR, I was wondering why you didn't use the .357 maximum case to make a .243 GNR, or a 240 GNR ? I'm looking for a small bore .243 or .257, in a revolver to hunt varmints and up to deer size game with. I'm thinking of your Wyoming Hunter.

250 Gnr or 251 Falcon, for a non stretch frame revolver. The Coyote Classic would be a good one to look at also.
Believe the Raptors are for for Contender or Encore. Gary will let you know whats best for what you're wantinh.

even our stretch frame. The Banshees are your best bet. They are the same ballistics as our 250 GNR or 251 Falcon and a bit easier to form cases. The Banshees would be fine for small bodied deer and other smaller critters.

When I developed the 256 GNR I experimented with the 357 Max case necked down to 243 and got set back in a revolver. Not all the time, but frequently I got a case that set back and locked up the cylinder, so I stopped with the 357 Max down to .257 caliber. But if whitetail deer is your main game the 240 or 255 Banshee are your best bet.

I think you would need 240, 255 Banshee or

Vern is right. The Raptors are too long for a revolver,
