What'cha doing air gun related today?

The last few months I have been shooting the Texan .308, love that PCP. I also have a AEA Challenger 357 big bore that I have been neglecting. Since I have the 308 with night vision I went back to a day scope on the 357 and zeroed in, WOW I forgot how bad that trigger is! I have done some work on it before, took some of the lead off and polished it. Yesterday I did some work to the valve, polished stem & seat also took 1 coil off the return spring, opened transfer port from 0.450 to 0.470 and polished. Removed 1 of the 3 hammer spring pre-loads. What I'm trying to accomplish is more efficient air delivery = better velocity with less air pressure and better trigger. Here are some before numbers with a bad trigger. Was tethered
Having had a karma EQ for a couple months I have to admit I think the AEA regulators are slept on a little bit.

To be fair my reg was a bit rough but I put a little silicon oil and a few drops of ballistol in my fill hose and let it work it’s way through the gun and I get strings very similar to that in terms of spread and deviation. Maybe not quite as tight as yours cuz that’s outstanding wow.

What does the P-factor mean?

Power factor is mostly used in competitive shooting (like USPSA or IPSC) to classify ammo into “minor” or “major” categories for scoring. But for airgun tuning, it’s a handy way to track energy delivery trends without converting to foot-pounds. Don't know if you saw it or not but, I'm shooting tethered, its non-regulated pcp and running with an external regulator.
 
Had not shot the Zelos in a couple weeks.
So this morning I went to the local range.
Got it dialed in with the JTS 18.1 and the H&N Baracuda's 18.13, they hit the same spot at
25 & 50yds going about 960fps at 2,000 psi.
However, the H&N Slug HP's are just a tad more accurate, but hit lower and slower.
I'm as happy as a Tornado in a trailer park :)

All are 5 shot groups.

It’s insanely easy…. You do have to expand the hole in the stock though. It goes where the regulator gauge goes. Uses the same o-ring. I used a Dremel to expand the hole in about 5 min. Then the gauge goes on the bottom of the plenum with the included bonded washer. Including degassing and refilling the gun it’s about 30-45min depending on how meticulously you open up the hole.

The box just slides open and has tiny little alan keys that you just use to tighten the box. It just slides over the plenum and when tightened it squeezes like a clamshell so no risk of a set screw or anything. Quite sturdy. I’ve actually used it to rest the gun while shooting a dove. lol definitely not load bearing but it’s not so fragile that you’re afraid to move around with the gun.
Sounds like a pretty easy fix! I would love to see a video process of the install to make it easier. Thanks man!
 
Pulled my Pathfinder out of the safe and shot black walnuts from 25 to 40 yards. Then saw that my sweet wife put out some old apples at my 50 yard station. So shot them up with some CPHPs and then some Hades. The hits on the apples where very satisfying, watching the bits fly off. The Hades out of my Pathfinder are simply outstanding …

It's a lot of fun watching the fruit explode! Good times. Lol

Here is an update from page (118) 1st pic is the after and the last is the before. After completing the modifications to get the AEA trigger to be on the same level as the .308 Texan. It was a huge success. cocking so much easier, trigger pull will rival my Texan, and with the same PSI and to boot I gained fps, in the next few weeks I'll shoot some targets and see what we have.

If there is anyone running the same pcp and would like the same from there (AEA Challenger 357 big bore standard side lever, heavy hammer and spring, 3 washer spring pre-load) Please let me know I will post what was done.
That’s outstanding.
