New cartridge

[Jimm]

Thanks to inspiration from "Buffalobob" and "Roy in Idaho" ( lunarlopes and front ignition respectively ) . I have been working on what will surely be the utmost in long range cartridges .

Initial tests are very encouraging . A 10,500 gr. projectile at approx .( sorry , approx is the best I can do as it blows the Oehler skysceens down at 40 yds . ) 1900 fps should be serious medicine for all of us "Long Rangers" .


It is only fair that I give a "sneak preview " of the loaded round as I am sure most if not all here will be lineing up to order their very own 90mm BBGun ( Browns Big Gun , name stolen from Abinok , but don't worry , he didn't copyright it [img]/ubbthreads/images/graemlins/grin.gif[/img] ) [image][/image]

Please , please , no need to jostle one another like that , there will be plenty to go around .

The deposit will be $6400.00 Send certified checks or cash only.

Later on I will give more info as I see fit .

Hey guys, do think this will fit in a short action.

[Buffalobob]

So what kind of action are you using with that.

That would make a good aardvark round. Takes a lot to stop a charging aardvark.

Now you gone and done it!
Can't believe you stole my cartridge name! 90mm is a good start though, so I guess its ok...

However, just for that, ill post my "big one" but ill have to go to my other hobby to do it. Ive got a feeling mine is bigger [img]/ubbthreads/images/graemlins/smile.gif[/img]
coasting BC was measured at 9.6 above 1400fps, 17.4 below
ill post a pic tomorrow.

Probably not as much as it takes to stop a charging wife(master card)!!! [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]

jimm,

I'd recommend a hollow projectile (would still be plenty heavy enough and would have same BC). The hollow would be filled with a fast burning powder then sealed with a calibrated fire brake that would not be breached until 1" from the muzzle.

The charge in the case would launch the projectile. The charge in the projectile would then maintain velocity for a treater distance. Would extend the range by at least 50%.

Also that bullet may have sufficient room for installation of GPS guidance.

I think you're on to something there.

BTW, I think its too short for a flash tube. [img]/ubbthreads/images/graemlins/grin.gif[/img] [img]/ubbthreads/images/graemlins/grin.gif[/img]
