Anyone know if the .22 barrels are still a gamble? I ask because I picked up a refurb and I'm going to be giving it the SSG treatment like I did with my .25. I figure if the results with it are good enough I'll use it as a backup/buddy gun to the AT44.
.22 Marauder barrel?

If it's not, I have put a Marmot Malitia barrel on mine and it shoots quite accurate now.

To my knowledge, Crosman has never really done anything different in regards to .22 barrels. If you get a bad one, it is rather easy to tell. Push a pellet in and back out to look for any engagement on the head or skirt. The problem tends to be oversized bores. They are too big to shoot available .22 pellets decently. I have verified that the issue is oversized bores by sizing bullets to fit and getting great accuracy with barrels that won't shoot any pellet to an acceptable level.
If you have any issues, feel free to contact me and I will do my best to help.

Thanks AJ. Also like NM suggested a marmot barrel is a possibility if I do end up with a wonky factory barrel. But I'd rather not use a barrel that requires such frequent cleanings or lubed pellets unless I have no choice. Especially considering I burnt through a 350 count tin of pellets working on my .25's SSG setup.

JDShapp - I hear you on the frequent cleaning of the Marmot Militia barrel, but since installing that same barrel in my .22 Marauder earlier this year, I have shot over 7,000 JSB pellets through it. Is the barrel accurate? YES! Do I have to clean the barrel often? Yes? Is it worth it? YES!

SPC-Racing. How often do you clean yours. I'm close to 1,000 round now and It still is shooting spot on.

I know that Jim designed his barrel around the 18gr jsb pellet and for good reason. However, there is another .22 cal TJ barrel that was designed by Sean Perro and Bob Sterne. If what I was told is correct, it shoot alittle bit of everything very well and doesn't need choked. I am sure Jim would machine one of those blanks as well. If not, Roy at Mountain Air will.

Aaron,
Scott recommended me to shoot the 15.89 most likely because it's shooting at 27 FPE. I have been happy with the 15.89's so I haven't tried the 18.1's. I had him set it up for shot count and not power as this rifle is really for my son to shoot and not hunting.

It stands to reason that the 15's shoot very good in a barrel designed around the 18's. I just prefer unchoked barrels.

I had purchased a 22 synrod, did not clean it, stock settings, just shot it, with JSB 15's @ about 750 fps. They were OK not great. At 25 yards about an 1.25" in a 10 shot group. Then my order of JSB 18's came in. What a difference! At 25 yards pretty much pellet on pellet in a 10 shot group. At 50 yards I'm at about .5" with a 10 shot group. Sad thing is, my first synrod that I had was absolutely crap! Made me doubt my skills as a shooter, waste of money on pellets, air, time, targets. It was a nightmare. In terms of time frame, I bought my first synrod in the early fall last year, the new one about 4 months ago. I am pleased with the one I now have but I can not attest to the others. Good luck.

I will have to try the 18's. Understand your reasoning, less maint.. Would be nice to hear from people that have the TJ barrel.

The Gaska barrel is also made by TJ. Unchoked has nothing to do with maintenance either. Chokes are bandaids for the lack of pellet consistancy.

I got a chance to do some shooting tonight after work. Went through my usual assortment of .22 pellets I have on hand at 25yds. Once again I tried pellets from the bad batch of JSB 18's and got the same result as I did with my AT44 with them, two different POI but consistent grouping on those two points. Air Arms 18's did the best, and will be what I base any preliminary tuning on. H&N Barracuda Power second best, but not great. I'll have to give the few Beeman Copper FTS I still have left a try in it when I get a chance.
I'll be seriously considering the Marmot Militia barrel down the road, but for now I'm going to focus on an SSG and aiming for 40+ shots.

Small bit of updating on the barrel situation. I shot some targets tonight at 25 and 40yds both with the Air Arms 18gr, and 15.9gr JSB. The JSB's didn't do very bad at 25yds with .45 inch CTC, the Air Arms did far better, in fact they slightly edged out my AT44 with a .33inch CTC group. At 40yds the Air Arms opened up to .48inch CTC.
Next step is running some shots over the chronograph before I put in the SSG.

I have a older one I must have gotten lucky it shoots great. Crossman domed hollow points from Walmart shoot better than any thing with it. One hole groups at 25 yards with most of the time.

I got in a few shots over the chronograph today. I only shot 18gr. Currently they had a max of 811fps, average of 792fps, and a low of 762. I have to say these numbers aren't impressive compared to my AT44. However I'm willing to bet with a bit of time I can get her up to the 860's with the 18gr like I want.

Yesterday I got the SSG in, and tonight I ran a few shots over my spastic shooting chrony. If its right or even close to right then I actually have it shooting to hot for my tastes in the 890's. Even if it is wrong its definitely hitting hard, much harder than it was before, and at least the accuracy is still there. I can definitely see some potential for it.

Looking forward to your results!! Sounds like you got a decent barrel and that is the main battle with the .22's.

It took a little trial and error, but I found mine did best with the 5.52mm pellet head diameter. I have a older Gen I M-Rod.
I too recently got the WAR SSG. Right now I am trying to fine tune (no pun intended) it to get 30 good shots from 3kPSI to 2kPSI.
My first tune I tightened down the locknut to expose 0.3 (caliper measured) of the guide rod screw end.
Not so much. Got high power, but seem to lose shot counts.
Now I have it set to 0.150 exposed.
Have not had a chance to test it. The temp dropped under 30 degrees and the chrony is picking up the air coming out of the barrel across the front chrony sensor.

The pmod I just purchased will cloverleaf at 25 yds with Diablo jumbos and the crossman premier pellet will do almost that good, nickel size groups are common. I do get occasional flyers with the premiers.
