Hi all!

I just stumbled into an old Crosman 130 in .22, and while it has definitely been around the block it seems to be holding air. While I did hear some slow leaking while pumping it at the shop, and even a pop from the rear when I dry fired it with 1 pump, it now holds 2 pumps very well (to my ear) over at least a 12 hour span. Cool! I can play around for a bit before the seals truly go south.

Chony numbers are 300fps for 8 pumps and 325 for 10 pumps using a 13.73 grain wadcutter.
I hardly expect the little pumper to be a powerhouse, but that seems low to me.
Can anyone tell me what numbers I should expect from a healthy gun? Is 400 fps with any pellet realistic, or is 325 pretty much the right speed for that pistol?

Thanks all!
 
I had one I resealed and it was not really as fast as some of my other pump guns but as I recall it was over 400?
not what a Benjamin will be but nice for poppin small vermin and paper.
they are easy to rebuild.
be careful pumping it to much you will lock the valve up.
if the are working correctly they lock up up pretty easily I never pumped mine past maybe 8 pumps
 
Found a Tom Gaylord post that explains a lot.
Also found some other posts that mentioned factory velocities that are just about what mine is producing. And it's Crosman info listing velocity as 359 @ 10 pumps. 👍

I don't think that there's a valve or seal problem with mine, which is great news.
It's a nice change from having to rebuild or repair stuff just to try it out!

BTW - does anyone know where the nose cap on this pistol came from? I've seen many pics of the 130 now, none had it so I'm guessing it's an aftermarket item.

very little guns I was thinking the D120 but still be careful that valve will lock up I dont think they change the valve design until the next generation but I am not 100% sure
 
According to that article, the "trigger valve" in the 130 did away with valve lock problems, at the cost of increasing the trigger pull weight as pressure increased. Though at 10 pumps, the trigger did not seem much heavier to me than at 3. Very little difference, and the trigger is fine - modest but safe pull weight, clean break.

I don't believe the 130 was ever considered a powerhouse but it should shoot between 300 to 400 fps. Fun little pistols. This is my restored 130 and another rebuilt one without cosmetic restoration.
