........Use Viton..........
How many shots are the viton o-ring good for??
I suggest that you try using 2 pellets of T7 behind a Barnes 250 gr T-EZ bullet. I don't believe that you need the 150 gr powder magnum charge as all it does is give more recoil. JMHO & here is a fired Barnes T-EZ bullet that took a nice buck at about 45/50 yards with 2 pellets of T7.I just received them. Not have had a chance to shoot the CVA MR yet with the O ring installed.
I can tell you that the breech got very dirty during zeroing in.
I used 150 gr Pyrodex with a 250 gr powerbelt aerolite bullet. Groups of three full cleanings between each group.
That was at temperatures between 67 and 77 fahrenheit. Cutting paper at 75 yards.
Temps now reaching 100's (Arizona) so I will have to wait to get up north before I shoot again.
I would be glad to let you know how the O rings do if you are interested.
Also heavily considering change of powder type and amount as well as bullet brand and weight .
Don't want to beat the firearm up and I aint getting any younger.
Suggestions would welcome.
sorry if I bent your ear.

I don't know. I'm still running the first one I put in.

Triple 7 has a tendency to form a hard crud ring where the base of the bullet seats when standard shotgun primers are used. This can cause a dangerous situation if it prevents seating the bullet firmly on the powder. The primer manufacturers are aware of the issue and some have developed special shotgun primers in response:
CCI Muzzleloading #209 In-Line Primers
Federal Premium Muzzleloading #209 Primers
Remington #209 Muzzleloading Primers
Winchester Triple Seven Muzzleloading #209 Primers
