I have just bought a 45.100 sharps custom rifle built on a Greener Martini Shotgun Action. This rifle is a take down and has express sites. I can not pick it up for about 8 weeks so time is going to drag.

Can any one tell me about the strength of this action and the cartridge. The only thing I can find on the cartridge is in the cartridges of the world. The rifle has been tested with both black powder and nitro loads. When I get my hands on it, I will try to puts some pics on the forum.

I would like to be able to safely get 2200 fps with a 300 grain projectile with the nitro load. Is it possible out of the cartridge. This would be about 27,000PSI I believe and have been told that this would be safe in the rifle.
