Is it possible to take a M1903 or m1907 Browning and reaming the chamber to say .38 super. will the barrel and the frame take the force of the new cartriage. Ive hurd of useing a bushing to go to .380 ACP. i would rather go up not down.
 
These guns WILL NOT handle 38 super or even 9mm.
I use to consider my self lucky to get $100 or 150
for these years ago when there was a bunch floating
around

.380 is considered to be a safe round. However, I did shot a good number of 115gr 9x19 ammo using original parts including barrel (reloading numbers are the same, so I went for it). However, you may end up with broken extractor since 9x19 is 1 mm shorter from 9x20.

Now, I have some supply of original 9x20 ammo, so I'm set for a long time.

I bought a stripped frame/receiver from TradeEx for $10 a year or so ago, then collected parts from any place I could. At the end, I got my own 1903 for $170. Lots of fun. I also managed to get a few thousands of a new made ammo from Sweden, kept some and sold most of it at $25 for 50 here (couldn't afford to keep it all). Thus, I can't complain.
 
The Browning Long has a 20mm case length. The .380's is 17.27mm. You can't make a chamber shorter. Inserts tend to come out easily.
 
9mm Browning Long ammo can be made by trimming .38 Super/.38 ACP cases to length and loading with .38 Super dies.

Converting a straight blowback pistol to .38 Super is a disaster waiting to happen! Even the short recoil Colt Model 1900 in the dimensionally identical .38 ACP does not have the strength to handle the more powerful .38 Super loading.
 
Does any one know what kind of performance the 9mm long cartridge had?
I think it's a shame that ammo for these neat old pistols is so hard to find.
I was thinking that rechambering to 38ACP/38super and loading it lite would be an easy way to put a 1903 back in action (just don't mix up the ammo).
 
It's only hard to find up here.
take a look at the Sarco/Samco website and you'll find pallets of the stuff, both non-corrosive and corrosive.
 
The 9x20mm Browning Long fired a 110 grain bullet at around 1100 fps.

I would recommend against rechambering the gun, both in the interest of originality and due to the possibility of a 38 Super round finding its way into the gun. I think it would be better to simply trim .38 Super brass to the correct length.
 
I just checked the balistics for the 38 auto 130gr bullet @1040 fps.Thats close enough to the 9x20 for me.If I had one of those pistols I might actually do it .MAYBE.
