Data from my modded Crosman 1322

Florida_Man · Jun 7, 2021

I'm going to try and keep this going to make info available on the web. I will have another for my 2240XL build that will be starting from stock form.

I am able to use a Chrony and Labradar luckily. The first round of data is from an indoor bench just to get the muzzle numbers.

I am starting with Crosman Premier 14.3 grain dome, both airguns prefer these pellets.

The Mod list

AlchemyAirWerks PUMP RP VALVE AND BRASS PISTON (not flat top)

25% Max flow port bushing

AlchemyAirWerks Steel pivot pin

AlchemyAirWerks STAINLESS STEEL BOLT PROBE

AlchemyAirWerks roller trigger

AlchemyAirWerks Power Hammer Spring

Crosman 14.5" barrel

AlchemyAirWerks steel barrel band

You should give a shout out to "wyoman" here on AGN. He is without a doubt the undisputed king of 1322 and 1377 pumpers. He has modded them for years. Stuffed valves, hogged out valves, modified pistons, hammers and barrels. He can really give you some knowledge on the 1322 for sure. Use the search feature and search for some of his posts. You won't be disappointed.

My 1322 has way too much money into it. I also have the air works valve and port. It's a very good mod but I found it really didn't add much velocity until I put a 14.5in barrel on it. I think I'm getting velocity in the 600s now but it's been a long time. Even a 12in would likely give you more power than you might think.
