can only source locally made slugs and they offers different dia. as other .217 and .218. BUT! the .217 is actually measuring from .2173 upto .218 and the claimed .218 start from there and goes to .2185!. those .218/5 never grouped well and was worried they damage the liner and i ditched them anyway. since i cant get my hands on proper slugs i wanted to know what are there tolerances. using them on impact M3

THANKS!

That is gnarly! I have seen some guys posts shooting into duct seal with as a great medium for catching pellets/slugs.

I was kinda suprised it didn't make it through, stopped 117 ft lbs of energy. Not being held in place helped absorb some impact, the can got knocked back instead of being fixed in place.

I use the 30mm 3-12 44 Centerpoint on both my Zelos. It’s amazingly clear and best reticle for older eyes like mine.

If it works it works I have them on 5 of my guns

Leon you are welcome to come over and hang out with us anytime. Bring your guns and gear.

One experience I had from two years ago was three consecutive .22 barrels that were very aggressively rusted to the point of visible pitting in the center. I think maybe some bluing salts got somewhere they shouldn't have and were not flushed out. When I finally got a rust-free barrel, it was it was reverse hour glass as your .25 is. That was the end of my interest in Hatsan.

NRA range in Fairfax allows pellet/airguns. Also check out Izaak Walton park in Centreville. They certainly allow powder burners but is worth checking out and ask if they allows airguns as well.

Gun is now guite silent.
Huma-air moderator is added felt and hammerspring is adjusted for lower fps.
Rifle stock did need make more space for hammerspring bolt.

It shoot now 847 fps, but need to test more how fps stay when shooting more.

Gun is now 55mm longer and weight is +40 gram for stock.
Shorter moderator setup was making more sound.

Not anymore. You snoozed you losed.

I used locktite blue to good effect

happy birthday.. I believe your best guns are the 45,52& especially the 54..as I have gotten older I can't take the recoil.

Yes, a consistant hold; That is the reason for the best individual fit. I would not even have a bullpup without an adjustable butt plate. Bullpups are awkward until you get them fitted to you, then they are good. I shoot a right-handed rifle left-handed.

Those rings are needed for the huge objective bell you have. Look at how high a bullpup gun scope has to be mounted to get a decent cheekweld. Your scope is closer to your barrel than alot of other setups that have to clear a tall mag or receiver.

Thank you for interesting thoughts. Interrelation of hammer spring tension and regulator pressure is very interesting. I like to play with measremments of different depensencies, unfortunately I am a bit restrictes just having Hatasan Flash QE. I install the regulator though. Looking for buying Hatsan Factor RC, it seems to have aall parameters adjustable.

You only need to measure the outside,then get the push on lens caps,forget the threads thing.Let me guess the Bell IS 56 MM.
You can always go to their site and get the measurements there to.....

The forecast currently shows PM rain on Sunday. We will be keeping an eye on this as we get closer to setup. If the forecast predicts the rain to start in the morning, we may setup everything on the ranges. Otherwise, the plan is for the red and green courses to be setup at sporting clays.

Those 32.3gr Smooths are a great projectile!

You must have a faster twist barrel in your gun. I have 17.7 and one is a 15.75 and both work fine.

Ha, I also grab any old cardboard box and don't bother putting a bullseye on it most of the time.

There is a conflict with the shotgunners, they hosting a tournament and will need the field for the weekend. Sorry to have to cancel this one.

Probably won't see anything on the target. If they are both accurate I would shoot them in the wind and see which does better. If they are the same....go with the cheaper option

I find it interesting that the LGU/LGV is universally loved by owners, highly sought after in the used market, and yet was DQd by the manufacturer. Ditto the ASP20 and the FWB sport, both come and gone. Not an encouraging sign for the high end spring gun market. Glad we still have a few choices left.

The Wildcat has a very specific reassembly protocol. Unless you marked the position of the air tube clamps, it likely will not function correctly.
Is Ernest Rowe's Masterclass video the one that you watched?

It's pretty well accepted as a good video to reassemble the rifle.

I was going by his “high power tuning” vid. But il watch and save this one. Thanks a bunch!

kwaping said:

Yeah, I certainly don't need a 5K2. Besides not wanting to wait longer for the K1, I also think getting an overpowered compressor might make it more durable and reliable. And hey, maybe I can start a tank fill business and have it pay for itself!

Click to expand...

Funny, if you watch all the Mighty Moose YT videos, he mentions the 5K-1 and 2 could be used to start a busines and fill air guns and tanks to make money.

I think I’ll pass and just hope I can get lucky with 3-5 years with taking great care and not over stressing one.

Best of luck with yours!

I am glad you replied that. I thought it was to high. But thought I may be a cheep skate. Sometimes I have 80's prices stuck in my head

OK - I can see how there could be value there if going just for higher power out of whatever you have on hand . . . but it is not "universal" in that it does not apply as well to intentional lower power tunes and shooting. I think there (like 500+mm barrelled .22 calibers shooting under 20 FPE as an example) Scott's rule is likely better - at least more usable and applicable. Again, there may be a way to combine them into something even more usable for a "universal" decision guide.

For lower power shooters, I think your observation could be misleading. For example, with your rule, for a given caliber a short barrel needs less plenum than a long barrel, even if the owner wants the short barrel to shoot at higher power and the long barrel at lower power. That's what happens when one ignores actual air usage - that's where I think Scott's guidance is more likely to result in a better tune (at least in terms of air efficiency and likely shot cycle).

Since I'm not one to go where you are testing I'll leave it alone and for you to figure out (I set one of my .25 cals up for over 90 FPE once, but found no good use for it so brought it back down into the 40s). As for the too much plenum observation, I found that on that very gun when I tuned it back down - the ES dropped a good bit when I dropped the plenum volume back into the range of Scott's guidance and retuned the gun for that level.

Peace out . . . moving on . . . happy testing and shooting!

Again, not what I was doing. Whether or not this applies to low or high power was not a criteria. It was, as I have stated, optimizing the volume of a plenum to the volume of a barrel. My objective was, within my small sample, to determine at what point increasing the size of the Plenum provided diminishing returns in energy.

I had ignored plenums for years. When I started playing with AirForce rifles and a Huben MAX-ATH regulator and its 50CC plenum I discovered why they are important.

So I decided to find out just how far you could go with a plenum. Where in fact was the optimal size for a specific caliber and length of barrel.

Whether anyone uses what I've found is up to them. I use the data to set the size of plenum and then use the regulator to set the energy level.

Properly optimized plenum allows for a lot more shots with a given bottle size. Because it allows you to set your regulator pressure to the absolute minimum for whatever power you are looking for.

The example I shared earlier. .25, 25.4gr pellet with consistent 927fps and a regulator at ~1750psi. I put non Huben adjustable regulator on that gun and had to set the reg to, I think, 2400psi to get similar results.

As for low power, no reason an optimized plenum could not be used. Depends on lower bounds of the regulator and the various control mechanism in the gun. I can see where regulated pressure could get too low for the gun to operate. Pretty sure the lower bounds on the Airforce style hammer and tophat guns is below the general poppet style.

But I've never gone the low power route. As I noted the Condor has high flow valve, heavy spring, and heavy hammer. I have 2 setups, the 927fps and ~1100fps. 50cc plenum and 125cc plenum with different reg settings.

Pyramid has the regulated flash, and under its specifications it says 250 bar max fill. I would assume that is the maximum safe fill pressure.

Click to expand...

Yeah, probably. 250 bar give me only 38 consistent shots. pellet speed drops after that. So, it is 3 full mag, at 290 bar it is 4 full mag, but I got a bit nervous.
