The concept of a "fill and dump" cartridge is incompatible with high power and efficient air use, regardless of caliber.... If the cartridge is large enough (compared to the barrel volume) to have a high average pressure during the shot, then it will be loud and inefficient, blowing a large percentage of the air out the muzzle after the bullet has departed.... The only way to have lots of power and efficiency at the same time is to have a large quantity of air on deck (to maintain the pressure while the valve is open) and to close the valve well before the bullet is half way down the barrel and use the expansion of the air in the barrel efficiently.... It's pretty simple, really, dump valves waste air.... Bob
Got some trigger time with the MAC 35 today and must admit I am impressed. Spent yesterday shooting other big bore guns( Draggon claw, Recluse, Evanix Sniper .45, and Evanix Max ML .357) and was happy. But the consistent shot to shot velocity and repeatable accuracy of the MAC 35 was far above the previous days weapons. I can't wait to see what it can do once it is broken in.
In the video I saw where as he ejected a cartridge it flew out like a real gun, do they plan on making it where it would be a better way to get them out instead of maybe having to catch them? Im sure that this is only a prototype?
They are working on a sporter version to be released next year. And on the ejecting case they are rugged and not hard to manage. It is a new design and not everyone will like the cases, But they provide advantages. People transitioning from powder burners will be pleased. Plus you can carry 25 loaded cartridges easyer than filling a recluse every 3-5 shots from a pony bottle. A way to avoid cases falling on the ground may be in the works I will ask next chance I get.
this is a little different
Pro marking! High quality video, cool music and effects, and a hot girl and they will sell some. Just a fact of modern business fact.I can see appeal to both ignorant ( as in uninformed ) PB folks, though the tank costs will likely shock them, and, to some "tachticool" airgun folks.In one video it seemed the person being shown the rifle/carts seemed to have the cartridge pointing just a bit towars the company owners head? Please never show up at a shoot and fill one while pointing the cart my direction! A foster "could" let go and likely wouldn't have a positive impact ( funny there eh?) on whomever/whatever it hit. Safety first."Off to the range" well maybe hunting accurate?? First time human error? It does take a while to get used to any new rifle.Then again a first time shooter(of this type airgun)And a "prototype" off the "assembly line" has been tested-again w/out detailed info- but I "thought" prototypes were somewhat mage one at a time and assembly lines make large runs ? Just modern English usage I reckon.Lowest base price of $999.00 sounds good , and market research does show folks like numbers like that MUCH better than $1.000 even. Change back from your grand! Again, good marketing will sell some.$20 per shell-2 included at base (projected) price. HUNTING power. Not sure (as no "facts" provided) as to what weight ammo will hit 400fps using 2,000psi, and it will be quite at that level, would a .35 JSB weight around 70G? Making about 25fpe? That would hunt squirrel but you will need good shot placement if you try it at 50 yards. and no weight given for max power-but max power stated as 120fpe-no weight/fps given- if charged to 4,500psi and a full 4,500psi will be no problem for those with good compressors at home."0" fps ES was stated no where, I seem to recall someone somewhere saying 1-200psi variance on fill though-all bleeders are different though-.Made in the USA, that sometimes help sell also.Another US company does make a 120fpe regulated .357 that will give 20 shot off a 200bar fill and you only have to carry pellets.The "match grade barrel" , well I hope so. I can not begin to imagine the hassle cutting the lead must be to get a smooth transition into the barrel one might think the outer lip of the shell will need to be milled into the barrels breach end(?) and figuring the correct angle for both pellets and bullets placed into the shells must be a nightmare. Any chance this 50-60 year old shell design is what is going to be used in the new rolling block rifle another company is to release soon? Or a redesign of such that is at least similar? So I do see those 2 markets, PB folks who will fire it a few times, and tacticool airgun folks who will enjoy it at first then only bring it out to show others. As a real hunting air rifle, "I" don't see it competing with DAQ, the Koreans, airforce or RAW. It is new therefore cool but in the reality of the airgun world I see it selling as well as the Hatsen( I think, might have that wrong though) .25 pistol. But if someone in TN gets one please do stop by (and please bring 4,500psi of air with you) as I would enjoy firing one a couple of shots. Truly.John
Pretty simple.... more power takes more air, either volume or pressure, or both.... If you are using a dump valve (which is the case here) the larger you make the cartridge relative to the barrel volume, the more air goes out the muzzle after the pellet has left.... You may not care about efficiency, as each cartridge only does one shot, but the number of cartridges you can fill from a tank, or how much pumping you have to do to fill them, goes up the bigger the cartridge....
