Took the old Crosman Model 70 to the range and tried a period Nikko Stirling 6x32 on it.

Off a bench, at ten yards it got 10 shots into a 4 x 5 inch 'group'. Verily, tis like a cylinder-bore 0.410 shotgun.

This is the worst accuracy of any air-rifle I have ever owned, on a par with the worst air-pistol I have ever owned.

The trigger is abomination, granted, but this is a fixed-barrel, recoilless CO2 bolt-gun with a rifled barrel. Whatever can be going wrong? I am going to try a different scope on it and see if that is the problem, but once that is eliminated, what can be going on? Do these things shave pellets?

I was expecting 1" groups at 10 yards, but this is ridiculous.
