Panthera FX Panthera MKII .30 700mm My First FX

Wow Bill! If you like this trigger, than you are going to be over the moon when you eventually get an AAA. At least in my examples, no comparison. The other thing, probably because I never had a bottle over 300cc before, is that the 580cc bottle gets quite warm filling. None of my regular guns get as warm and the pressure settles down with cooling.

I would not waste too many good pellets trying to get a 1 in 16" twist barrel to shoot them any better than you just did in those conditions. Play with slugs until you get your pellet liner installed.

You're observation, on the noise suppressed, mirrors mine; not that loud w/o but really quiet with. Considering the power, super quiet!

Having just gone through taking mine down, I would bet your air leak will be with the reg or the fill, because the rest of the gun can't leak through all the loctite.

I switched back to slugs this afternoon. The Ghost trigger is not the best. The Sonoran is better, but difficult to find the right balance under 12ozs.
I’m very happy with how quiet it is.
I was hoping that the valve was leaking.
*EDIT: I read this in a thread, but cannot confirm it is a fact or or if it is even recommended and so I deleted it.

Im surprised you guys don’t like the trigger. Mine on the drs comes to a nice wall and breaks at 8 oz. How did the slugs do?

I was hoping that the valve was leaking, because I didn’t leave it cocked. I didn’t realize that it was supposed to be stored cocked. But, I don’t think that is the issue.

Wooh, back up, where did you read that this gun was supposed to be stored cocked? I have missed seeing or hearing of this, completely.

I read it in one of the threads. But, FX does not state that. I’ll delete it, there’s enough misinformation, without me adding to it.

OK, that's what I thought, I'm calling B.S. on whoever said that. Nobody designs an airgun that needs to stay cocked that I know of. And if I knew of one, I would never buy it. There is always someone, that's afraid of everything, that will be shouting that the sky is falling.

I like the trigger. Didn’t go very good with the slugs. AEA 52.2gr slugs, used same tune as for 50.5gr pellets. 110bar. I had three flyers. I can’t explain the circular chain group lol. I’m sure it had something to do with my setup. I used my electric rest setup for free recoil. It allows the rifle to recoil backwards on bearings and rollers.

it’s not usually healthy to keep springs compressed for long periods of time.

This was with the front rest, but with a Protekor front bag. Hopefully, I’ll have my new rear rest finished tomorrow and I’ll try that. Maybe I’ll increase the regulator by 5-10 bar. It definitely has something power.

 

[Solo1]

What was the velocity?

 

[Billm]

Around 92-925fps. It fell off the reg. 920-925fps

 

[Solo1]

Id up the reg try 950-970

 

[Billm]

Id up the reg try 950-970

I’m going to try a little higher and see what happens. Maybe I’ll swage some slugs and see what happens.

Before you try swaging just shoot for a while to get used to it and break everything in.

I tried the new rear rest today. It’s not really finished , but good enough to try. I also swapped the digital scope out For a Discovery 6-30x.
I think I have the AEA 52.2gr slugs nearly dialed in with the FX Panthera MKII. I guess you could call this cherry picked if you want. It’s the last five shots fired from the Panthera MKII. Yes, it’s the best today, but it’s the best because I’ve been playing with the tune. It’s not cherry picked in the sense that I picked the best group from earlier in the day. It just so happened that the last group was the best today.
I’ve tried a couple of Reg pressures, 110 and 116 bar. I’ve tried multiple different hammer spring settings. One thing that I believe about the FX Panthera MKII: it is more hammer spring sensitive than my BRK Ghost or Sonoran. It could be my imagination, but it seems that just changing the velocity 10-20fps with the macro and micro HS adjustment will determine if these slugs group tight or shoot Sporadically. It’s the longest and fastest barrel that I have, I don’t know if that makes a difference on how finicky it is.
The winds were higher, but dropped to 10mph. The first shot had a lower velocity than the other four shots and if not for that dro, it would’ve been a very nice group.

Coming along good Bill!!

 

[Pumacarl]

Nice shooting! Yes, the big ol Macro dial points to the fact that the hammerspring is the thing to mess with on these guns. lol

Hey Bill, I use graphite on my hammerspring, hammer and trigger, but I was thinking of trying MoS2. What do you think?

btw: You might want to take a purge shot if you are using the Amp reg. Gerhard said that in one of his videos.

Well done good shooting!! Getting together with the new toy thats the way!

I’ve never used MoS2, so it will be interesting to see how well it works. I still have a jar of that microlubol in my cart lol.

Thanks. Yes, I’m really liking it so far. Of course it’s early days lol
