Interesting thanks Pauly.

Just for the hell of it I ran some shots on my 362 tonight. It has had some work done on the valve, hollow probe, increased hammer tension, reasonably straight forward stuff. At 16 pumps it shot 21.3 ft/lb, but there was still a little bit of pressure left, so there's not much point pumping more until until the valve can dump it better.

Using 18.52 grn H&N

Pumps            ft/lb
4                      9.38
5                     11.32
8                     15.6
9                     16.9
10                   18.01
12                   19.5
16                   21.3

So as BC Clark says, there is really a lot more that could be done to develop pumpers, but at 4 pumps, that's a respectable bit of power I reckon.  I see they have put out a pcp version of the 362 called 3622 I think.

My first airgun was Crosman 760 with rifled barrel.
Easy to shoot accurately compared to springers since there's very little moving mass. Less hold sensitive.

Then I modified a Crosman 2289 pistol (.22) up to around 19 ft-lbs with short barrel.
Made it into a 23 ft-lb rifle with a stock and long barrel. Shot out to 100m.
Around 30 easy strokes for full power.

Then turned my Crosman 760 into a 50 ft-lb pistol.
Also a ground-up 100 ft-lb rifle with free floating barrel so the pressure doesn't alter the accuracy.

The pumper platform is really under-appreciated by manufacturers.
I don't see anything with the quality of high-end springers or PCP's
so it seems a really good pumper needs to be built up.

Ive got Kruzas 362 and love it, has steel breech and some pauly5 flow through bolt and suppressor, arm gets a work out if plinking.

Ted's Hold over on YouTube has done some reviews lately on pumpers.

Kruza, I can’t find your review of a 1322.

Years back I had a Crosman 397. It was sort of ok, but I got tired of having to pump it all of the time so I sold it. I’d much prefer a co2 or springer, if pcp wasn’t an option. Cheers. Declan

I have a Sharp Innova .22 - there's a thread on it's refurbishment here.

I haven't personally tested mine in terms of power but pumped 8-10x the internet generally reckons in the 18-22 fpe area.

As for accuracy, my recently refurbished one put pellets into a 10mm group at 20m.  In the past I've shot 1/2" groups at 30m.  So pretty accurate.

Accuracy doesn't seem to be affected by pumps, more like the pellet you choose.  I am confident I could stack pellets at 10m with 4 pumps with the right ammo....

I have the 1322 and had a 362. Both were accurate 20m. Reviews on both are on the site.
