Top left group looks great. When I did shoot mine outside (37 yards), I fired two groups with the Crosman hollow points and quickly switched to the domes. Seemed like the HPs were very erratic - at least for me. The H&Ns load very smoothly through magazine. I know what you mean about single loading, I actually use two fingers (one on each side of rifle) to load singly. Going to keep playing with tune and try and determine if I’ve lost any accuracy. Would like to get accurate shot count a little higher, seems like about 20-25 really good shots before they start dropping a littleSounds like you got it dialed in.
I shot two testers on paper and 2 at the steel target. So shots 5-9 are the top left. 10-14 left middle left, and 15-19 were bottom left. 50 yards light breeze bushnell 2-7x32 (japan). That took me from 3000-2200 psi.
For giggles I shot 10 more at 75 yards 4" gong. Shots 20-24 were hitting the target then at shot 25 the sound change and no longer hitting the target appeared to be dropping fast and I was under 2000 psi at this point. This is with cphp I'm waiting on a shipment of premier domed. And contemplating the larger pellets mentioned above. How do they feed through the mag?

Probably closer to 20-22. Need to do more testing. Starting at 2800 psi, 21 shots (one dryfire after patchworming barrel) pressure dropped to 2000 psi. That’s about where shots seemed to start dropping (not much, but noticeable)and your getting 25 good shots on 2800 psi?
Haven’t seen any print higher, only dropping when pressure reaches a certain point. Really need to get it outside, hard to tell a whole lot from short distance in basement - 11 yds.are yours vertical stripping higher impact point as you approach higher shot count.. that's what mine is doing until it starts falling sharply "shots after 25". Of course the fall off at 50 yards will be greater.
On plus side my waist band has shrunk from the pumpmaster 3000.On plus side my waist band has shrunk from the pumpmaster 3000.
Just shot 30 new crosman premier they group ok my shooting wasn't great but I was in a hurry and didn't give the 30 minute rest after pumping what is now 70 pumps (think that pump is losing steam which is disappointing. Does anyone know how many fills from a standard aluminum scuba tank I think they fill it up to just 3000 lbs).
started at as close to 3000 psi and ended up at 1800 psi with pellets losing steam on last 5. Sounds like we are pretty close on # shots per fill. Looks like 25 shots is what you get and if you need 5 more as your walking out of woods aim a little higher.
Nice job!Just wanted to share this real quick...
GTA member K.O. got a photo of the crown on his .22 cal Crosman Icon:

And that got me to thinking, what kind of cost:benefit analysis can possibly justify the factory using this atrocious crowning technique?
I clamped a barrel to my bench and imposed a 10 second limit on myself to crown it. Three (3) seconds with a carbide burr, followed by 7 seconds with a diamond ball.

One try. No practice. No retakes. I'm sure a capable manufacturing engineer could optimize it down to 5 seconds. So when we look at rifling wiped out at the muzzle, the only logical explanation for it is sheer apathy and indifference to quality control.
ive looked not going there yetOn plus side my waist band has shrunk from the pumpmaster 3000.
lol Have you started compressor shopping yet?
I know the feeling, that's a whole 'nuther rabbit hole! I wound up buying a cheap VEVOR from Walmart with 3 year total replacement warranty (expecting it to go bad) Happy with it so far though.ive looked not going there yet
Going to start playing with my .177 today (inside where it's warm and cozy) I bought one of each when they were on sale, and have concentrated on the .22 so far. If you don't mind me asking, what sort of groups are you attaining so far? What pellets have you tried?I was getting only OK groups from my .177 ICON, so I recrowned the barrel today and they did tighten up a bit.
Still only able to shoot at 10m, once the contractors are gone I can shoots at 25m.
