Here is the updated version of my sniper rifle revolver. I've tried to take into account as many issues as I could. I beefed up the stock and bipod and reworked some of the inner workings.
irearm - Sniper Rifle Revolver
Caliber - 8x68mm custom reduced taper
Weapon Type - Revolver Rifle
Operation - Double Action
Capacity - 6 Shot Cylinder
Loading - Swing out cylinder (spring action extractor arm)
Scope - 8x
There was some issue with my original choice of tapered ammunition, how it would expand and jam in the cylinder. I have overcome this problem by using a reduced taper on the casing and reworked the extractor. When depressed, it tensions a spring which releases, applying an greater instantaneous force, prying the spent shells from the cylinder.
