I decided I'd replace the pump first , make sure the rest of the
pistol functioned . It does , but I can hear air leaking thru the
reservoir seal when I pump it . I did manage to get a couple of shots
off before the seal failed , and I think it's worth a few more bucks to replace all the seals .
With today's seal kit purchase I'm now into this project a total of
just over 33 bucks . I may decide to replace the barrel too depending on
how accurate it is once I get the seals replaced .
Unless somebody has been shooting steel BBs through the barrel its
likely (sans lead fouling) as good as it was when it was new. Lead
pellets are typically dead soft lead. They are not hardcast like pistol >projectiles.

Older models had a magnetic tipped probe kinda needed for holding BB's
in place. They changed this at some point and the new probe was no
longer magnetic and no mention of shooting BB's in the literature
anymore...
This one has the magnet in the bolt . Can't really see down the
barrel well enough to tell the condition of the rifling . I just pushed
a pellet (miked .1755") down the bore from the muzzle , pushed easily
and didn't engrave the head or skirt of the pellet at all . Is there
enough air pressure on the pellet to expand the skirt into the rifling ?
No, that's a myth from what I've read. It might have a smooth bore. I
don't know about this particular Crosman...

Appropriate manual (per your year guess) and parts pdf's can be found
here:

It claims to have a rifled steel barrel in user manual. I'd try some different pellets, see how they fit. I've accumulated quite a few
different brands and styles of .177 pellets. Some fit in the barrel
really loose, some snug and others really tight. That's why you try a
variety of them in your gun and see what works best with it. It can
vary from batch to batch of the same brand/style too🙂️
Some pellet barrels are choked on their ends too, similar to a shotgun.
