Title: .30 caliber discovery (help)
Post by: Air Rifle Hunters TV on April 06, 2016, 06:35:55 PM

Sometime around this Christmas I plan to convert my .22 discovery to a .30 discovery I want to get up to 70 fpe and any help would be greatly appreciated on how to achieve this with jsb pellets I already found a big bore discovery breech so the breech part is fine but it is 1/2 inch od so if anyone makes barrels that will port them so they can be used that would be great. I also would love steps on how to bore out the gauge port and valve well please, make them detailed.

I would get in touch with Don Cothran at Cothran machine . He might have a barrel available . he does have everything else you'll need .

I have two Cothran PowerHouse valves, one in my .25 2560 and one in a .30 3060.  Both are beast.  Don should have all you need or he can get it (barrel).  I plan on getting a Disco length tube for the .30. 

PM me your number if you want to talk.
