Panthera I Jumped In!

Yeah, 140b is a good number for a stock gun, but if you've got the biggest port in the business and a heavier than standard hammer and are only shooting slugs 33gr up to 43gr, than 150 to 165b is really popular with a lot of people too. At the end of the day I want an accurate powerful efficient shot, in that order. This gun is about making what used to be called 'seemingly impossible' shots, not a lot of ho-hum ones, or super precise paper tigers either. It does very well. I have zero complaints about it's inherent accuracy, it doesn't seem to have nodal preferred speeds either. Today, after a week in the truck with some hot temps, the reg (Huma) had zero creep, no purge shots needed at all. Since I can get it to perform at just about anywhere on the dial the next logical thing to chase is efficiency. So far everything I've tried always ends up at about the same shot count, depending on weight 20-24 shots. There just might not be an efficiency sweet spot where I'm checking, it might be below 140b. If so, screw it. I'll just leave it at 140b if I can get 975fps for the 40's and 1040 for the 33's there, and leave it for a while. The only way I'd see myself experimenting more after that is if I had to use a hand pump to fill the gun all the time. lol
 
I shot this today for the first time in 6 weeks. I have been spending most of my airgun time on the G3 mrod lately, but I never finished figuring out this gun to my liking before the G3 came out. Anyways, after six weeks zero reg creep, my first shot with the H&N Precisions was the same speed as my last shot six weeks ago. That's pretty damned good for anything but for an FX, wow! I'm going to be really upset when the new wears off of my orings, and life goes to normal.

I went back to playing with the hammer spring settings, trying to figure out the correlation between the Macro and micro settings and if the 33gr and 40gr always moved the same to each other, with each change. I could have just done this over a chronograph but instead setup for some reaction target shooting at the same time at 158y. It wasn't terrible in the shade, but it has been muggy lately. Long story short, still inconclusive results. If having a lower/higher Macro/micro makes any differences when adjusted to get the same velocity, then I don't know what it is. I don't see how that I can play these two adjustments against each other and get the speeds that I do. Usually you turn down a hammerspring and things slow down, but in this case I can always make up for that with the micro adjustment and get the speed right back up there. Macro at 7 or 22, and utilizing the micro I can get my target speed right back, and the gun shoots the same. I'm not noticing any increased or decrease harshness or harmony either. It's all pretty much the same. The only difference that I notice is between the 33gr and 40gr slugs themselves. I like how the 40's sound, but I like how the 33's fly, better.

I'm thinking that at this point it doesn't really matter what's going on if I can get the results that I want. If at some point I can't, then I will revisit it, until then I'm just a dog chasing my tail. Bottom line, I'm very happy with how this gun shoots, which is a lot better than me. I love my tripod too. What a game changer. I never would have gotten into distance shooting at this point w/o it. I'm done laying in the dirt, using a bipod, with the ticks. It's just time to shoot what I got.

macro wheel is irrelevant...speed and hammer tension respond to where the micro wheel is sitting

It would seem so, wouldn't it? There has to be more to it than that though, I would have thought anyway. I thought someone would say something like, "it only starts doing something at lower reg settings," or along that line, because I don't want to go there anyway. Strange, that I can't remember reading any threads about this stuff.
 
The micro adjusts the hammer spring pretension, The Macro wheel is a ganged adjustment. Like guidodg states, the micro is the actual adjustment. The macro slides the whole adjustment carriage back and forth with a cam. I like to find the approximate velocity range that I want to be in with the Macro Wherl and then note the setting on the vernier scale . I then set the Macro to 13 and then adjust the Micro wheel to get to the previous noted setting and fine tune from there. If you were to find 3.5 was ideal, it doesn’t matter what combo of Macro and Micro settings you use, if the the vernier reads 3.5, it is mechanically the same.
This guy gives provides a good animation of what’s happening. I’m not sure that I agree with his description of what is happening though.

I only have two regrets with buying an FX. One is that I didn’t buy one sooner. The second regret, is that now I feel compelled to buy a second one. The rifles are very accurate, but are built more like a delicate instrument that needs to be coddled to get the most from it. If @Pumacarl hadn’t warned me of what I was getting into, I might have a negative view of my Panthera. But, he gave me enough information, for me to know that I wasn’t buying something that is built like a tank. But, as long as there are threads like this one, all is good.

I have seen this video before and it makes perfect sense to me, but he isn't accounting for reg pressure either. You can't do it all, well, with just the Macro/micro. And like I said, I can turn my Macro down to 7 and still get 980fps out of 40gr slugs just clicking the micro up a little. So the upper 2/3 of the whole range of the Macro is just a playground. And, it's not like If I turn it way up I will get elephant stopping power either, lol. I did stop turning the Macro down at 7 because I didn't want to run into an area where I get a slug stuck in the barrel, so I can't say for sure what happens on the very low end. I have different guns for low power anyway.

The way I understand it, is that the Macro is for changing shooting conditions, kind if like he states with needing less power indoors. Kind of like the power wheel on the BRK Sniper series , where it changes the transfer port. If that is the case, it’s not of much use to me personally. I’d rather have a different rifle for different needs. But, that is just me. I have enough time remembering the ballistics for one setting. I wrote this before I read your last post.

I put off getting one because I knew that it would come with a lot of clutter from all of the stuff that I would feel that I needed to work on it properly, and I would be forever fiddling with it; and I was right about that! The amount of easy accuracy it has is intoxicating though when it is on, which is usually, mine's still pretty new. If you're starting to get bored with regular airguns, with regular issues, shooting regular accuracy, FX will have you praising and swearing in no time. THIS is the hobbiest's brand, that's for sure, you've got to love the whole process to get involved. To buy one of these and just shoot it as you get it? I certainly don't want to, and won't, be talking about that. That's a waste, not the money spent, but the potential just doing nothing. Any of the airguns out there today can be adjusted once to shoot very well, to buy one with ultimate adjustability and not touch it, what's the point in that? I would also add that if you're going to buy something and not touch it, buy something that's as tough as nails, and that's not these. Here's where I say that this is just my opinion, because it is just that, it is not really a discussion point, because I have thought about all of this stuff for years already. Everybody has got to do their own thing.

Now, I feel you’ve challenged me to not leave the G3 stock 🤣😂🤣

I think that after seeing that prototype stock @BenjeneerJohn was using at PAC, you might want to just hold out for one of those. They really need to get their custom shop running again so people could have access to this stuff and then they would really know how interested people are in something. Not to mention, it is another revenue source, and it's good for their image, which again, translates to revenue. Pump out a few beauties with wood stocks and carbon fiber bottles and see what happens.

Well I started going over the FX this morning. I missed something on the photo that UA posted of the gun, so I might have to eat this, as all sales are final. If you zoom in on that picture you will notice that the adjustment lever screw for the cheekpiece lever is missing. You can see the screw in the butt stock lever clearly. I emailed UA about it, we'll see what happens. I can't believe that with all their handling of the gun, that nobody checked function of the adjustments, or that it didn't just fall off on its own.

Now that I know what to look for, the missing screw really stands out, even not zooming in.

Now that’s a most awesome rig if I say so myself self!! Love the stock and looking to put one on my Dynamic 25!🤠🤔🤗🤗🤠

I love the Panthera platform a lot… so much scope for personalization

I came up with these 2 iterations after swapping their barrels and plenums around

I’ve installed 700 cc bottles on the front of both the Panthera and the Dynamic for more shot count due to power mods for longer range in the 30 and 25 for ground hogs

I didn’t see John on the range and so I missed his stock. I’ll have to try and find it in the photos.
