I need some counseling...

I'm necking my thermos jug down to a phonograph needle!

Expect 12,500 fps using Varget!!

Prime her with a stirrup pump?

 

[CJ6]

Is there a powder with a burn rate slow enough to make it work? I run RL 33 in my .22-.284.

I'm thinking he has Kingsford charcoal on speed dial.

About twenty-five years ago I was writing for Precision Shooting Magazine. For various reasons, I ended up building a 22-378 Wby AI. Did some barrel coating testing for a rifle company.

Any way, I am completely remodeling my gunroom. I found the reamers and dies.

I'm getting this uncontrollable urge to build another one, and just fitting a barrel to my Savage 338 LM.

Rich,

There really is no hope. But if you want to spend some more cash before buying the barrel, I will let you sit on my couch, tell me all about your troubles and your plans, and i will only charge you about $100 an hour. But I suspect after all that, you will build it anyhow, and a bunch of guys here will want to see the video!

Ledd Slinger I bet you can't melt a Barnes.

 

[okie]

Couldn't you get it reground as a .17?

ha ha lol!!

Rich , go for it . Charles Cummings in his book Everyday Ballistics calculates that a 3 Grain Phonograph Needle ( of unspecified Metallurgy ) in a 50 Caliber Case burning 240 Grains of unspecified Powder could reach 10,000 FPS ......so you have something to shoot for ! Weatherby built a few 30-378s for use with light Bullets around 1960 . Special 100 Grain Speers got to 5760 FPS , and really special 30 Grain Bullets got to 6438 FPS . Homer Powley & Bob Hutton used a 22-284 with 50 grains of 4227 and 15 Grain Bullets to reach 6585 FPS around 1963 , and Dr. Eickhorn of Burroughs Corporation used 31.6 Grain Bullets ( in a 1:24 Twist Ackley Barrel with 54 Grains of 4064 ) to reach 5350 FPS also around 1963. Of course , none of these are recommended "SAFE" Loads for you Big Case guys .

I wanna see a gun that can make a projectile reach orbit!

 

[Frankr]

Is this guy test firing one

no my mistake that's a flame thrower

No don't worry the bullet is long gone,has already went threw the target 1,200 yards away.So you do not have to worry about that muzzle blast melting it.

Gerald Bull did it. Was called project HARP

 

[hpshooter]

Gerald Bull did it. Was called project HARP

Which lead to the Iraqi supergun project and, eventually, Dr. Bulls assassination.

Never reached orbit.

They already tried that at Aberdeen. They ended up calling it a grenade!

Actually it did reach orbit. If you are referring to sustained orbit then no it did not but it did achieve "Earth's Orbit". Same principle as the latest miracle gun, the rail gun. Those guns were mainly built to test re-entry vehicles. Vehicles which would have been missiles launched without rockets. Objects can be launched into orbit but if they don't have sufficient velocity to sustain orbit they come back down. That was the the goal with HARP and SHARP.

UH,like shooting 50 cal bullets through a 30 cal bore?

Orbit is orbit, like being partially pregnant, it either is or isn't. 'Space' is not orbit, 'space' is an arbitrarily defined elevation, 50 miles by NASA, 100 km by FIA. The projectiles reached 'space' they did not reach a single orbit let alone sustained orbit at LEO. Shepard was the first American in space with a ballistic flight path, Glenn reached orbit.

Orbits are not equal. This explains a couple and the altitude to achieve them, and tyhe time they stay in orbit before returning to Earth.

A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi), (orbital period of about 88 minutes), and 2,000 kilometers (1,200 mi) (about 127 minutes). Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss.

HARP achieved the altitude required for orbit. Unless something has changed, that altitude probably still stands as the record for a non rocket launch.

A low Earth orbit (LEO) is an orbit around Earth with an altitude between 160 kilometers (99 mi) (orbital period of about 88 minutes), and 2,000 kilometers (1,200 mi) (about 127 minutes). Objects below approximately 160 kilometers (99 mi) will experience very rapid orbital decay and altitude loss.[1][2] The orbital velocity needed to maintain a stable low Earth orbit is about 7.8 km/s, but reduces with increased orbital altitude.

Geosynchronous and Geostable are more stable and but they require 35.000-42,000 KM altitude.
