After trying several scopes, and mounts to deal with the 'spine-snaping' recoil of the "48" - I realized that the WHOLE situation had to be delt with.
eg:
1 - rifle mounting to the stock.
2 - scope mount(s) - even "Dampamount" to the barrel.
3 - actual scope mounts (clamps)
& anything else that could possibly come loose - even a TINY bit.....
... LOCKTITED them all...
... shooting
fine & steady now...
