Panthera FX Bull barrel for Panthera

[Auto1191]

It’s rude to answer question with another question but I think it matters to know what the application is.. basically hunting or target shooting?

Target shooting is simple: accuracy trumps all as @Solo1 has stated.

Hunting is more complicated. What is the target critter? What’s the ideal range vs the mostly likely range? Do the slugs have different designs? If one slug is more accurate how much more accurate? For example let’s assume one of the slugs is the 40gr frag slug and the other one is a standard 34gr hollow point.

If I was shooting squirrels and rabbits I would choose the 34gr. The 34gr will do less damage to the meat and fur if you want to salvage that.

If it was coyotes I would say 40gr frag no matter what, assuming accuracy is acceptable. Why? Because in .22 cal that’s the absolute best slug you can use on bigger bodied critters. I’ve seen how devastating they can be. Be warned you will get some pass through with this slug but expect 2-5 small holes as they break up like the X-punch slugs.

In other calibers you can just shoot heavier and achieve excellent results but in .22 cal you wanna make sure you’re doing as much damage as possible.

I am going to give the 40 grain Frags a good run as well as the 40 to 42 grain, This rifle was designed to handle the 40 grain .22 slugs. I want the accuracy to be on par, . I didn't purchase it for PLINKING LOL. This should be a HP .22 dedicated slug rifle. I am not using for completion. It is supose to be a long range rifle. 100 yards + easily For those purposes I will not shoot the larger critters, if you know want I mean, @ long range. But @ closer distances with great patience , anticipation and shot placement I will . If it doesn't work then I have proved it to myself. A long time ago all that one used the most was 22 LR. I am in search of high power .22. Is the FX Panthera up to the job? I will find out I think @ 50 & under it can be done. This is my window of being on the safe side so to speak in my opinion. If the Panthera does't perform as expected, I just purchased a expensive .22 slug rifle that does not fit the bill. It will be a hard lesson learned, especially for the wait time I indored for this rig. With all the extras I put on like Bull Barrel, 300 bar bottle, bag rider, & compact NV bridge. As for optics DNT Thernnite 635 R. as well as my trusty Sightron S8 4.5 x 40 x56. I started this thread @ the begining, I hope it all ends well. If not it will be a hard pill to swallow. Iwill move on , & just unload the Panthera for someone else to enjoy. Also, I woun't change the caliber to .30 for this wasn't my Intial purpose. Like I stated HP .22

With the 22 lr did you mostly take head or heart-lung shots while using 40 gr hollow points?

To answer your question -Heart & lung. I haved used my .357 AAA Slayer in the past , with great sucess, out to 68 yards plus, with no hick ups. As old as that rifle is, It is what I call a true performer. I just had Allen Z , repair the dreaded slow leak, It has been holding air now for 3 months strong. He did his magic & machined a few do dads. Even with a slow leak with the Slayer, for hunting purposes , will get the job done. I put 200 ronds through the Slayer, for checking my dope for it is UN-REGULATED

As far as the DRS"s I will aquire @ one point or another . I purchased them Knowing what their limits would be. They will be a joy to shoot, simple as that.

I am so fed up with waiting for the Panthera, I should just get a .22 Raw, put a true slug barrel on it & call it a day

Don’t know what kind of power you'll get with 40’s

Was working on the railroad car today replacing the window in the roof. Have one more to do in the roof and 3 on the sides that were taken out by hail. Could only do one a week with my hands. Will be doing the video for you on the power I have I set at now before I set it for the max I achieved when experimenting when I got it several years ago

I will be ready

You should be able to get close to 80-90 + ft lbs out of it min with the 40 grainers I would imagine. You’re just going to have to run a higher reg to achieve it. Until they enlarge the valve body by 50 percent to flow more air quicker before it shuts down.

This is true . Even FX will require high reg pressure, .22 being subject to this , being .22

These aren’t a like-for-like comparison… 99% firearm ammunition is made out of much harder alloys than Airgun slugs. They don’t expand the same way.

Airgun ammo doesn’t deal with heat or as high of pressures as firearms. Even with rimfire which don’t always use jacketed ammo you’re looking a much harder projectiles than an Airgun slug.

That’s also not taking into account that the slug I’m advocating for is a fragmentation slug. So a slug that’s designed to open up explosively AND made out of buttery soft lead is not gonna behave like your .22LR projectile.

Bro is over thinking it. How big are your coyotes? We talking 20-30lbs desert sage jackals like out here in Utah? Or 40lbs mini wolves like in BC? How furred up are they?

I ask because I know the 40gr is fine for EITHER one but the only thing that’ll change is the distance.

The 40gr have a BC of around .19 and the Hex slug have a BC of .115…. Your frag slug will have a lot more Fpe on deck than my Hex did at 155y…. You’re worried you’re gonna have enough for yote at 50y or less and I’m saying depending on size you’re good to 200y!

Take a deep breath load some frags up and feed one to those coyotes. Tonight, tomorrow, next week… I don’t matter you’ll have a dead coyote on your hands.

You already have the right slug, only thing missing is making the right shot. Head, chest, neck at sub 100y it won’t matter much.

Y’all think I’m kidding when I say that Airguns have completely replaced rimfire as a hunting tool, but I’m not. Not saying every Airgun is better than every rimfire. To be honest it’s mostly a tie depending on your shooting style. What I’m saying is that with these $1000+ guns we have can be tuned to do anything you would want a rimfire to do.. but the Airgun will be more fun and honestly it’ll kill better.

Yes it will kill better… go shoot a jackrabbit or ground hog at 150y with a .22LR and then do the same with a 71gr hybrid boat tail doing 900fps…. I’ve got a few hunting buddies who will tell you “if I have to get shot give me the powder burner not the air…” A slug that penetrates, expands and does NOT exit is a lot more difficult to deal with than getting ice-picked by a .22LR or 17HMR round.

I don't know about "high" pressure. I have had my .22 Dynamic block pushing 40gr slugs over 100fpe with only 155b. I have never even tried it higher but it's there if I want it.
