Crosman 362 Anniversary Edition question

[baranjhn]

I just got my new Anniversary 362 from Pyramyd and it doesn’t dump all the air when pumped from 6 to 8 shoots. After I shoot, I cock it again to dump any remaining air. On 7 pumps I get consistent chrony numbers from 623 fps to 627 fps with 13.4 gr JSB, but on 8 pumps it can be erratic. Anyone experience this? Does the rifle just need to break in, or is it a warranty issue?

I would shoot it a while at least a tin or two

I believe most upgrades and mods that fit the 1322, also work/fit this rifle. If after breaking it in you still have the same issues. A slightly stronger hammer spring, or hammer spring adjuster would fix the issue of not completely emptying the valve.

This. A couple of tins fixed all my "issues" I was having with my HW75. Like an Italian Tuneup on a car, gets all the gunk out and everything meshes together better.

Hammer springs are usually fairly consistant, so I would think the hammer may be binding a bit in the tube. Shoot it for awhile first, but I would take it down and clean and lube the hammer and spring if it doesn't get better.

The hammer isn't able to release all of the pressure before the valve closes.
You could have a hammer spring issue as mentioned, but I just wanted to say that there is a point when you've reached max pressure. I can't imagine that being the case with only six strokes. The Sheridan maximum is 8 strokes, in order to dump all the air, in a properly functioning gun.

The 362 should definitely dump all the air with 6 - 8 pumps. At 9 or more they seem to still hold some air on the next shot.

Everyone's suggestion above is good. Try to shoot it a bit more and see if it holds more air on 8 pumps.

Thanks for all the replies and suggestions. I haven’t shot it all week, but I’ll get it out this week end. Hopefully it’ll break in, if not I’ll take it down for a thorough inspection.
