Jason Simpkins built my 50-90 Double rifle. He used an older Merkel 12 gauge. He used PacNor highest grade 50 cal barrels and sleeved those in. The barrels are short at 20 inches and the barrels are topped off with Express Sites.

The gun shoots very very well. Although the barrels are 20 inches it is a 75+ yard gun all day long. My eyes aren't as good as they were or it would be a 100 yard iron site gun.

I've always wanted an ultimate stopper gun. The guns balances very well and is fantastic to carry. It weighs about 9 pounds. But it packs a heck of a punch.

The 50-90 cases with Reloader 15 powder and those bullets mentioned above is in the vicinity of Light Nitro 500 Dangerous Game load.
