Crosman air pistol - General discussion / Re: 2240XL pellet choice

Here are my results with a modified 2240. 

The data look like a lot of fun - I reconstructed the table in Excel so I could examine it. Have you considered repeat testing at 20 yards to see how they fall out? Piques my curiosity, especially the tight group with the gamo pellets - never would have thought they'd be  that accurate. Thanks for sharing!

Here are my results with a modified 2240.  I too got good results with pellets around 16 grains.  But weight was not the only determinant.  Results vary by pellet type/shape as well as weight.
(Sorry for the poor formatting of the copy/paste of my spreadsheet table)

Crosman 2240 speed, accuracy, and sound levels                        
   Steel breech (purchased Crosman 2240XL)                     
   18" barrel from Alliance Hobby                     
   Boss Max valve, stiffer hammer spring, and hollow bolt probe from Alchemy AirWerks, 3.9mm transfer port from Alliance Hobby; uses about 1 gram CO2 per shot                     
   Bulk CO2 set-up:  fed from 250 gram / 9 ounce cylinder; powerlet eliminator from Alliance Hobby                     
   Falx moderator from Silent Thunder                     
                     
   Crosman 1399 stock                     
Speed measured with Competition Electronics ProChrono DLX                        
Accuracy is max center-to-center distance of 3 shots, from 30 feet, inches                        
                  
Session 2: Simple Caldwell stand; 75 degrees; 60% humidity; overcast; at least 20 seconds between shots

I was thinking of making a box around mine to capture the spent pellets. Any info on where most of the lead ends up (backwards of sideway/down) would be helpful.  :-*


In my experience, the spent pellets go everywhere. It all depends on exactly where you hit the target - on the periphery, near the hanger, at the bottom - they ricochet in all directions since the paddle on mine (a Caldwell, probably the lighter weight version) twists as well as pivots. I collect most that miss the target and end up in the backstop!  ;D

After just a few pellets, there were numerous bits of lead spatter embedded into the plywood panel on which the target was placed.  That has been my experience any time lead hits a largely perpendicular hard surface....it sprays little slivers out in a starburst pattern.

Great info.

I picked up one awhile ago with the steep discount, but have yet to shoot it. I made a wooden H-frame for mine to keep it steady.

Just tried a couple of rifles to get a sense of what it takes to flip the heavy paddles.  The answer is about 10fpe on target.

12fpe in .177
Distance 30 yards, terminal energy approx 7.5fpe:  No
Distance 15 yards, terminal energy approx 9.5fpe:  No
Distance 10 yards, terminal energy approx 10.3fpe:  YES

21fpe in .22:
Distance 30 yards, terminal energy approx 13.6fpe: YES

Note in both cases I was using pellets with a poor BC (wadcutter and hollowpoint) so that's why the terminal energy was tailing off so quickly.

The two I ordered were delivered today.  First impression?

WOW!



Thicker than a fast food hamburger patty!

I measured the Caldwell that I bought years ago and has 0.10" thick paddles, exactly half as thick.

Very nice.  I said I bought them for giveaways.  I lied.  One of them is staying with me!

Kevin, thanks again for posting it!

I've had one for several years now - be sure, if it stays outside, to oil the pivots every now and then - it'll rust there where it wears. I repaint both sides of the targets with fluorescent paint from time to time - the stickers have a tendency to fall off after a while. I've actually dished the targets with the PCP guns over time, but it's still my favorite reactive target.  :)

Great deal! Will give me a chance to see if will work on 7.9 grain .177 at about 550 - 650 fps from 10 - 15 yards.
