@Castin’Catchin’ 26 - I added the plenum extension to my Paradigm and Evol. That got the speed up for the slugs a bit higher than the normal plenum. My guns like the RMR 44g slugs which is fortunate. I'm shooting them around 900 fps. Haven't had any problem with kills at 100+ yards with either! I also had the new external reg adjuster add and it makes tuning a lot quicker, but you still have to go in and adjust the hammer the regular way. Derrik Wall did all the work and tuned the Paradigm for me.

Awesome! Did you get the plenum from AOA? How many shots per fill is this giving you?

I get everything from AoA wth regards to AAA parts.

I have my Paradigm a little over 2k on the reg. I get close to 25 shots before I hit the reg limit. On the 22 I get closer to 3 magazines or 33 shots with the reg at 2100.

Has anyone had a problem with their EVOL magazines jamming consistently? My EVOL .30 magazine keeps jamming with FX Atomix

I have had some issues with this. You can take them apart and adjust the spring tension. This helped in my case. Also make sure that the loaded ammo is not clipping on the inside. Have had that happen. Other than that, thats about all you can do I believe.

Early on in this thread I posted how to fix the magazine jamming and/or feeding issue. Post #75, page 4. Note that it really doesn't have to do with the actual cycling of the magazine, but jamming because the soft lead projectile is getting snagged on the machined corner of the magazine and tilting the projectile sideways some. Here is the steps (copied and pasted from the previous thread) I did to fix it...

I have had this happen to me a couple of times with pellets as well. Aside from now carrying a fiberglass rod in my case now to tap the jammed pellet back into the magazine, I also did some experimenting with the different magazines to figure out why it happens and completed the fix for it.

What happens is the very edge of a pellet head will catch this sharp edge of the magazine as it begins to exit. (Check out the difference in the two magazine holes, before and after.) This sharp edge is sometimes catching/dragging the edge of the pellet's head, which allows the pellet to want to move sideways in the magazine. Then, the extra force we apply with the cocking lever jams things up. Through testing, the solution was to cut, radius and polish the leading edge of the hole in the magazine. I haven't had a jam since, and can feel that there's no catching issues anymore.

Cleaning and polishing up the inside edge of the hole was easy enough with these steps: (1) Disassemble the magazine. (2) Working from the outside to reach the inside corner of the hole at an angle, take a razor blade and lightly cut the sharp corner off the hole, making the leading edge a 45° angle. One or two light cutting swipes all the way around the hole worked. (3) Polish the cut angled edge into a smooth more round radius with 400-600 grit sandpaper (I rolled sandpaper tightly around a small .050" Allen wrench to work the close corners and add pressure to the paper.) (4) Reassemble, tightening the screw so the magazine lid is closed on all sides and rotates with a little bit of resistance.
