Kral Puncher Jumbo for First PCP?

[Long_Gun_Dallas]

Forgot to follow up on bore paste. Some people use JB? Others use lapping compound. I use beeman chromoly lube. It's ancient, and I can't find it for sale anywhere. Not that I need to. The same tiny container has lasted me 17yrs. And looks like it'll last another 40, haha. 



Looks like your gun is already shooting very well

How bad was it to pump with the hill pump ?

@ghoststalker It's not all that bad actually... I'll probably be holding off a few more weeks to get the compressor, as it seems easier every time I do it. It's about four pumps per shot I find and takes about 5-10 minutes to top off. It will wear you out pretty quick, but it's pretty healthy. I'm 5' 10" and about 140 lbs.

I took a couple of pics of my setup today, really enjoying it so far.

Does anyone know if the puncher pro and jumbo are basically the same rifle with different stocks? I'm considering one of these rifles, but would want to put a regulator in. Huma makes one for the jumbo, but none for the pro. If they are the same, same regulator should work.

Essentially the same. Except larger bottle I believe

I think bottle and stock are the only difference. The puncher pro uses a tube, the jumbo has a bottle... Maybe the puncher breaker bottles will work on the pro? The puncher pro 500 has a 500cc bottle, but that's 75cc more than the jumbo. All in all, I really have no idea, I'd ask huma

Thanks for letting me know huma makes a regulator for this tho... That is absolutely getting put on here in the future. I found that pumping to 2900, or 3000 psi, (it's rated at 2900 psi, but the gauge is green until 3000), results in a poi change after about 30 shots... I need to do more testing with this to be sure it's not my scope, but the shots were flying high and in about a 3" group at 50 yards, but after like thirty shots it was pellet on pellet. Also, I maxed out the height on my TAC Vector Optics Sentinel 6-24x50 to zero it at 50 yards. I'll have to get a set of fx no limit scope rings I guess in the near future.

Hey Joe, I really love my Jumbo in .25 yes the poppet stem on mine broke after I tuned it up to 60 FPE. You can buy new hardened poppets on pyramid air for around $18. Other than that the gun is solid. I adjust my trigger by changing the sear profile a bit and polishing? Now it's a smooth 1lb 2 is. My gun loves jsb33.95 grain and AVS slugs out to 100 yards. I also put a carbon fiber Google from taking tunes and an Altaros regulator. I also bought a Huma regulator when I thought the Altaros reg broke. But it did not break it creeped after sitting around for a while. But then it went back to normal after one shot. This gun is super easy to tune and work on. Here is a video in case you are interested.

Is that your channel? I had already watched the first two videos, and knew about the altaros regulator, but I've never heard of that brand before that video. Huma on the hand is quite a popular brand. Any reason you stuck with altaros? Also, my gunbhates the 33gr JSBs but does amazing with the 25gr JSBs. I need to try some different slugs in it, but it didn't do well with the grizzlys I used
