I like your video. Informative , I've given mine up to 13 pumps. But never went beyond that , i.ll give it a try , ...up to 15 should be Good for my needs ! Thanks for sharing the valuable info ! 👍🏻

I'm new to airgunning and I learned quite a bit from this video. Since my guns are new I've yet to go beyond 10 pumps, I'll have to give 15 pumps a try.

Since watching this video a few months ago I've added the Crosman 1399 rifle stock, steal breach, 14.6" barrel and a Buck-Rail suppressor and I bought a chronograph from Amazon a week ago and finally got around the checking velocity. My 1322 rifle is shooting 494 fps with 12 pumps and 14.3g Crosman Hollow Points, 448 fps with 10 pumps and 17g Ruger Superpoints and 535 fps with 10 pumps and 10.3g Skenco Hyper Velocity pellets. My next 1322 project will feature a 24" barrel for even more velocity. I'm hoping to get to 600 fps/8fpe without major modifications. I don't hunt and don't believe in killing animals for sport but I'd have no problem with pest control and want to make sure my guns and I are capable of 1 shot kills which is so important when you have to pump your gun for a follow up shot.

I've got a 1322 with a RW valve and heavy hammer spring and boss t/f port, 14.5" barrell shooting 14.3 g crosman hollow points 628 fps. I replaced the roll pin with a stainless steel one and I shimmied it on the outside of the pump arm with tiny washers and no more slop in the pump arm. With the RW valve you can pump 30x if you want to and get 650 fps. But I'm not gonna put that much effort into it.

I always said that just by pumping it too 12-15 would break the 525 fps. You can feel the difference from the pistol and how the pellet hits the target. Nice numbers for stock.

great video very glad I found your site,

Do not eat a bean burrito if you are going to pump that much!🤣

Pumps with his hand still in there grip that's some strength💡

Looks like you've pumped out some vids on working on this gun. I'm playing catch up on vid watching. That's too much pumping to work on that, lol. I honestly thought about getting one but not sure if my hands will even let me pump it. A lot of days I can't even break my break barrel more than a few times and my shoulder pops out so I'm done and nursing it for a few days, lol.

I cant find your followup video showing what kind of velocity increase you got.

I’ve had so much bad luck with pumpers lately ... just give Me a good break barrel .

Man I hope you ate your Wheaties! Lol thats a lot of pumping! Trying to get caught up on my KZfaq videos. Been obsessed with the B3 project. The trigger does leave a lot to be desired. I have worked on mine a little but there is a lot of room improvement.

Hi I'm glad I found this video I just bought my first pellet pistol the 1322 I'm waiting for the basic stock to help me aim better but I really want to learn how to upgrade little at time your instructions was very clear and not to fast. I'm retired from work but always wanted one I hope to tinker from what I learn from your videos. Thnx again for taking the time in detail. I would like to know if there is a blueprint of the 1322 where all items are shown?👍🏾

Why did 20 pumps loose velocity?

Good Video!

First mod I made was the steel breech for a minimal increase.

Great research.

If you put the rifle stock on your Crossman 1322 you will feel like there is an increase in the FPS power. Hehe.

...You put one pump of air in it when you showed the 'wobble' in the pump arm....you must consider that when checking for residual air after 25 pumps....

Portability,,that’s why I like them,1322 a lot of power I don’t go over 8/10 pumps,same as 1377 ,,if you can’t pump 2240 all the way. I love Crosman handguns,that grip just feels great in my hand, I hope you enjoy yours,another thing,if I was shooting real guns I would be broke, I almost finished 2nd box of 1250 pellets in .177 ,,.22 more expensive…

I don't see any Pellgun oil on your table. With as many pumps and shots as you were doing I am sure your numbers would have been better with oil on the seals and pump cup. Maybe you did?

When I pump to 15 and shoot, the stock internals arent enough to dump all the air, and if I cock the gun again and dry fire, it puffs out about a pumps worth of air. Ive found that 14 pumps is my sweet spot.
