Tuning The story of a 30 caliber FX Bobcat named Terminator
- Thread starter pesty3782
- Start date
I have not, but the last time I had the air tube off it didn't leak overnight, and it didn't so any signs of leaking when I checked it with soapy water. I am thinking maybe the regulator might be the issue. I just got a rebuild kit so that will be the next step. Maybe one of the O'rings is nicked...

@pesty3782 The issue I had was that it would dump air somewhere within the stock. When I removed the air tube, it didn’t leak on its own from what I recall. When I gassed it up with the res screwed into the chasis, no problem. When I unscrewed it, refit the chasis into the stock, then re-affixed the air tube and stock it dumped air on me. I couldn’t figure out why and it was tough to take it apart to catch it before it got down to around 1000psi when the air dump would stop or slow. I purchased a new Huma reg, but didn’t install it. I sent i back with the rifle. I figured the issue may be a reg or valve issue, but I really didn’t know. I hope some of this info is useful to you.

HA! It's already been to the Big Leagues (EBR) in 2019... and did quite well I might add.Today I pulled Terminator out of the cabinet and noticed the air pressure was down to 120 barI thought I had all the air leaks takin care of.....So I filled it up with air and I just had to shoot it because there wasn't much wind this morning. So at 50 yards here is the 5 shot group...You can see above the other groups I got from it. If I can ever find the leak I will fix it, but I will have to take the rifle all apart again and I am not sure I want to do that right now.
Do I trust it to compete with it.....Not really, maybe a local match like silhouette or a bench rest competition, but it is not ready for the "Big" league’s yet.

My bet is the outer Orings on the Huma Reg. If it pushed in fairly easily, then more than likely that's the culprit. 15-minute job. Just go up slightly in ring diameter so that it slides in, but takes a decent push.

Well Mike I did order up a reg rebuild kit for it and it arrived a week ago. That will be the job next time I have it apart. The original reg that was in the parts bin, the O'rings were all shot. I will just rebuild it and see if that solves the problem....

Hi!!
Sorry if I revive this thread a little bit untimely...
Great story & great looking Bobcat.
I have a Bobcat Mk1 in 30cal. One of the first ones to come out in 2013. Older stock... Action can be removed from stock without removing the airtube. I love the gun, it’s just the best shooting gun I have ever had, has a little edge over my Fx Boss also in 30cal. (which I also love). Those 50 yards groups bring memories to me...
Right now it has a leak, but I’m determined to restore it. It deserves it!
Did you finally get yours to seal properly?
Cheers.

Yes I have the air leaks all done so the bottle holds air perfectly Keeping my fingers crossed… . I took it on a trip to Oklahoma and Texas (Took it for a backup for Textreme, but never needed it. After getting home it still holds air, but has a small reg creep…It went from 150-160. Not sure when I will work on that yet. Two dry fires and I am back to 150.

So finally sat down and took the Bobcat all apart again. I found a small piece of O ring under where the regulator goes and a small "dent" in the sealing surface where the reg sits. It's to the left side of the photo....... I again cleaned the reg area and also the valve area and put it all back together. Over 2 hours no leak.....I know not a long time, but I wanted to shoot this rifle again.....
So I tuned Terminator at 870 FPS and started to shoot it at 50 yards. I tried two different holds and it certainly liked it better when I didn't have a firm grip on the rifle. A lot of 5 shot groups at 50 yards could be covered with a dime. Here are just 2 of them.

Good to hear that you repaired it!!!
The dent is clearly visible in the picture. Did you do something about it, or just left it?

It's been a long time since I updated this thread. Terminator has held air and the same reg pressure since July 7th. I have been busy with a bunch of other things around the house and getting use to my Ghost 30 cal Specter....I have shot Terminator a few times at 50 yards and it does not disappoint at all.
I hope to get out in the next few days and sight it in at 50 yards again (Different scope on it now) Yeah I know Tweaker
.....
I will shoot it at a local silhouette match on the 23rd of this month then the rifle will be up for sale.
It has been an honor and a great deal of fun reworking this awesome rifle back to life for the next owner to share.

So I got out today and sighted in a new scope on Terminator at 50 yards even though it was windy here....It is shooting the 44's right at 860 and doing pretty good. All groups are 5 shots except the really small one and that was the last 4 in the magazine.
This one is the 4 shot group...
The two 5 shot groups were the first ones after getting the scope dialed in and then the wind calmed down and I shot the 4 shot group.....No cherry picked groups, just the 3 I shot.
Looks like Terminator is back !!!!!

I do understand what you are saying Mike, but it is time for somebody else to own this one of a kind Bobcat.
I just listed it for sale today without shooting silhouette, because nobody can tell me if the competition is going or not.
