457 Challenger 700 fpe 

The challenger bullpup is one of the best air rifles ever made, in my opinion at least. Absolute monster

333s shoot great, 300, 250s all hit same aim point, pure awesome😊

Let’s go mr. Hollowpoint

That 10.5 Donnyfl will increase the speed 10 fold

great video :)

Sweet !

He funk up!

Just in time for my t-Rex hunt! That thing is smoking

Nice video and good shooting buddy. But I got a question for you. I saw your video on the .510 but the bullet weights were light and I was thinking it must not be the 700 ft lb version. I want to get one for one of my buddies for a deer season gift since he just got married but I'm curious if he would do well sharing ammo with me. You know I like my awesome 385 grains at a time,

I managed to measure 600 GPE with a 240 grain, no reply from bin tac on whether you're "supposed to" use light slugs or not with it

Are all new challengers from now on able to do these fpe numbers right out of the box or is it a separate upgrade kit? Any plans to retest this kit with the .510 version? 700fpe at this barrel length is impressive. My aft lss with the tx2 valve 250bar 32 inch barrel no mods max fpe 770. 610 grains at 755fps. 445 grains at 830 and 245 grains at 995. Cheers

Hello mr hollowpoint, wich gun out of all the guns is your favourite to hunt with and wich one is the best out of all the 457's to shoot longdistance with. Thnx!

You know, Mr., hollow point. That's nice to see that you got your guns working at full power. With that new kit. But i've got two fifty Caliber air rifles And I don't have the upgraded kit And I really don't know how to do it anyways. I'm afraid I might tear up the o rings And the gun wouldn't work at all I just feel like I've been cheated. Because the gun should have come with the upgraded kits when we bought them to begin with 😢

Weak gun i could catch a slug with a catchers mit out of that thing texan cf long .457 is more powerfull at the same psi
