Spooner -My wants from this gun may be a bit different from most. I can say that for light shooting and smashing cans and targets around, a 14-16gr pellet and 5 pumps will give a days worth of fun for sure, that set up is probably OK for small pest also.As for me, I'm looking at 25-35 yard hitting power with lots of momentum in a small package. I'm using JSB Monsters but may go to 28.5gr Seneca Domes if I can get them moving at a semi decent speed --- I may need to go up to 8 pumps with them ?Right now my gun with 7 pumps is pushing out Monsters in the 485+fps range with 7 pumps (I have a larger transfer port coming from Alliance Hobby that hopefully will give me another 10-15 fps). If I can get 465fps+ with Seneca Domes I would be happy too --- I believe the BC of 22 cal Seneca Domes is above .042, but not sure ?For me, the momentum is important as I want Medium/Short range "Smacking Power" ----- game that can weigh in the range of 20 ish lbs.at the 25 yard range area or less. I have lots of PCP's that can handle this no problem, but this is set up as a short, self contained power source gun that is easily thrown in the car for a trip, no need for tanks, filling, extra Co2 bla, bla, bla.- just grab and go --- Could be a good small non firearm gun for a "Bug Out" scenario also !!Later folks,wll
Getting ~ 455fps with 7 pumps with 28.5gr Seneca domes ---- I'm in the zone.Looking to try the wider transfer port for Alliance Hobby when I get it to see if it adds a bit of speed to these Heavies.wll

If I can hit 550 with a 22 grain .25, I'll be dancing in the street.
I went ahead and ordered a max flow transfer port bushing from Alchemy Airwerks to see if it will boost it up some.

C362 & 1322 use the same valve assy. jk
Went home got the chrony, set up using 28.5gr Seneca Domes that were sized -- they were sized to 5.53mm - (a little bit too small I might add) and decided to see if I'm getting over that 455fps area I was getting when I thought the gun was leaking a little bit !!Well, I don't notice any blowback now, so I pumped her up 7 times and let her rip ---- 470fps, 2nd another shot 470fps and another another shot at 469fps --- I reached over that 465fps area that I wanted ---- I'm very, very, very happyI'm getting over 11fpe at 45 yards and have lots of momentum.I think I have found a 25-45 yard small sledge hammer :-)Don't know if I'll change to the max transfer port or not (why mess with success)- I'll wait on that and listen to all your thoughts and decide.Later guys,wll

Really not enough to support .25 caliber conversion or extra heavy .22 pellets. It could be enlarged some but then you will need to pump more times . If someone were happy with 500 fps or less it will do fine . I don’t like to go that slow.
