Airforce lss the most powerful production air rifle?

Air force became the most powerful production air rifle when they released the air force texan. About 500 ft lb of energy. Umarex wanted more power and created the 50 cal hammer with 700 ft lb. They claim and brag it as the most powerful production air rifle. But after 3 years they never release it. And now air force just released their new air force lss with 750 ft lb. How is umarex gonna claim most powerful if they cant even release a 700 ft lb gun to the public. And even if they do release the hammer, it's not gonna be the most powerful airgun.
 
Well I don’t think most air gunners want “The Most Powerful.” There’s a market but you’ve been around long enough to know the old timers were 10m guys, that a Walther 55 or FWB is still desired by any air gun fanatic unless they’re in it purely for power, stealth, big bore hunting.

My State just legalized small game & varmints. This I finally see a justifiable in my mind reason to buy a custom barrel/complete build in 6mm/.243 or .257. I honestly did consider (still see positive points in) owning a RAW .357 as that would take me to 300 yards with 81 grain Diabolos without the worry of something that carries 50+fpe to 500 yards and could easily bounce off a field rock in any direction it wants.

To clarify I guess you’re talking production only guns with no modifications in claiming that title of most powerful? Because otherwise there’s Air Force guns doing over 900ftlbs. There’s other smaller semi custom big bores doing 1200 fpe on HPA & 1600 fpe on Helium. Also, if anyone never saw it, one fellow turned a monolithic brass 600 grain spire point & topped 3000ftlbs with a dump valve just to see if he could do it. When he posted that years ago guys pointed out he’d broken The World Record for pneumatic power & had beaten the .30-06. He wasn’t interested in being recognized by anyone but fellow forum members nor did he want that stigma attached to our sport. 

There’s also the fact that NASA has been using compressed air for boosters & projectiles for quite a while. In a vacuum like space, 5000+ fps has been produced in testing. I don’t know projectile weight/fpe, barrel length or charging pressure but they’ve made anything we could ever do here look like a Red Ryder. Lol.

I’m curious about “The Hammer” though myself as it’s supposed to get 3 consistent shots with a lightning valve on a 3Kpsi fill & .50 caliber slug. I haven’t done the speed/weight to fpe that claims 700 fpe but I’m pretty sure it’s a 100 yard Whitetail rifle in main concept. I’m much more intrigued by Doug Noble’s, Boat Tail Bob’s, Nick & Dale’s work on higher BC.257’s that make shots on Coyotes & Groundhogs at 400-600 yards. 


 
Hey jamesd the umarex hammer actually makes those numbers with a 4500psi fill which is harder than you think to fill. I only know of 2 ways to fill an airgun like that and get any kind of shots out of it. #1 using a step up unit and 2 large tanks. Check out mr hollowpoints set up on youtube. Dude makes a living shooting big bores. #2 use a nitrogen tank filled at welding store to 6500 psi. None of that I want to go through but its an option. My understanding is that airforce is getting 600 to 700 fpe out of thier lss or just the full sized texan at 3000 psi. You get 3 shots with no real drop and then one 2in lower. I saw this demonstration myself. I think most people will use a gun like this to do an occasional trick shot or just to hunt with. Most airgunners do 10m??? I dont know about that. Most airgunners I know do all kinds of airgunning. Hft is very popular near me and those guys do 18fpe. I think alot of ag dudes hunt like me as well. Just saying that I might disagree with you on that. I would agree this is too much airgun to just shoot for fun unless you have multiple tanks and compressors and blah blah blah. I for one would love to ice a deer with a texan and its on my list.
