reloading the .17/50bmg Magnum

It's not the length of the barrel you have to worry about, it's the width.

If your Suzuki Samurai will pull a tank lowboy to handle that weight, you're all set.

Just to clarify. Are you talking about the 50 CCCR or the 30 CCCR?

 

[danweasel]

Shoney,

There's a 50?! Man, I should have done my research. I just grabbed up the first one I saw. No patience!

 

[JimKirk]

Why not a shorten 20mm ...say trimmed to 5" and blown out to 41 degrees!
Call it the 4.42 WSSSSSSM

Hmmmm... a true barrel burner...you get one shot, ...then replace the barrel...

Although it makes you wonder...how long of a barrel for complete powder burn...velocity?...does anyone make a cleaning rod long enough...I wonder...

 

[fireman 9731]

What kind of scope do you think would be best for it? 40-90x100 maybe?

That brass looks awfully thick around the neck too... you better turn the case necks for better consistency.

I bet if you just filled the case to the top with Varget, loaded a 36 gr. Varmint Grenade on top of that, you might be able to achieve somewhere around 12,000 FPS.

I want one

How many inches down the barrel do you prophesy that 36 gr. Varmint Grenade will go, 1.5767” or 1.9487”?

How many inches down the barrel do you prophesy that 36 gr. Varmint Grenade will go, 1.5767” or 1.9487”?

I predict that it will be vaporized approximately 1.7613 inches down the barrel.

With a margin of error plus or minus 38 feet.

 

[Shoney]

WWWWooooooo!!

That minus 38 feet is enough to scare my pucker string into inhaling a cinderblock sideways.

 

[Bwana John]

I like the sewing needle/40mm Bofers Improved better.

 

[KenWP]

The back thrust on a caliber that small would be amazeing trying to push that much gass out that small a hole. I wonder how long the barrel would last and the copper build up would fill the lands pretty quick.

 

[fireman 9731]

Maybe we could contact NASA and they could use the idea for a new rocket motor design

 

[Afy]

I think that the bullet wouldnt leave the barrel, and would be essentially left behind as copper fouling..

 

[Bruno2]

When I saw that pic I thought that was a 22-250 round . Kinda resembles one .

 

[Remo-99]

The .17 cal. projectile is a specially designed 45 gr. varmint bullet. The staff sacrificed a slight bit of velocity with this heavier bullet in order to get an increased ballistic coeficient for added downrange stability.

but we won't know for sure until we find a chronograph that registers above 9999 fps.

Lykoris, Once you exceed your chrony's maximum readout the conventional laws of physics no longer apply. This may require further testing to gather data on what forces are being or not being applied to the bullet once it exceeds 9999fps.

 

[Remo-99]

Oh and to further add, after finding a little more research on this topic(namely some SG-1 'documentries' on exceeding the conventional laws of physics).

Without the specialized measuring equipment required to accurately determin actual velocity. Failsafes would need to be put into place to insure the bullet remains at sub-light speeds, because as you know, at plus light speed if the bullet is still accelerating there is danger of it being caught up in a runaway cycle until it reaches the hyper-space threshold, where it will then pass through solid matter without resistance, resulting in minimal energy transfer to the target.
