My Benjamin sat around unused for 10-12 years. Always inside my home. What muzzle velocity should I expect? Chronographed it (8 pumps) recently at 657 fps, 14.7 gr H&T pellets; 640 fps with 18 gr ammo. Ideas to improve MV? Thanks.

well considering they say the gun shoots max 685 that's sounds about right with MV I don't thin you need to do anything except clean and lube the gun also do you best to inspect the riffling of the barrel for any hard pitting or rust and I think your pretty much golden speed wise its accuracy you need to look at lol
