9mm Browning Long and the Husqvarna 1907?

[dixda]

Hi,
I just got an Husqvarna 1907 in 9mm BL working to some satisfaction.
(It was bought in a malfunctioning state)
I cut down 38 super brass to the correct length and tried it with 9mm 124gr LRN.
The 3.5gr W231 charge flings the brass up to 20'(6.5M), is this normal for these pistols?
I bought Hornady 9mm 90gr XTP's (JHP)and want to try the same charge.
Is there anyone here with some experience to share? TIA, KD

I use starting loads for the 9mm Luger, and what you've got there is below a starting load. Mine doesn't throw the brass 20', but the distance thrown is dependent on a lot of things, and does not mean it's overloaded.

As Andy wrote, it could mean any one of a number of things. In "Cartridges of the World", Barnes lists his loads for 9mm Brng. Long as using a FMJ 95 gr. bullet and 5.0 gr. Unique and a FMJ 116 gr. bullet and 4.8 gr. Unique. He considers the factory load to be a 110 gr. bullet with FL powder, but no powder weight is given.

Be very cautious of useing loads listed in CotW. Some are very hot.

First off lets not compare the 9mmbl to 9mm para..Numbers might be tthe same but different cartridge. I had one of those beasts years ago and hand trimming brass was a real pain in the palm.I can't recall the load and I can't find any cases in my pile so I must have sold them.I do recall the brass flew past the old bedsheet we used for a catcher and I am pretty sure we did not use max loads from COTW.

That's pretty much what I wanted to know regarding the ejected brass.
At first I thought there was something wrong, so it's good to hear chasing cases that far is normal.
I use a Forster trimmer with an electric drill to get the cases the right length. It may be a pain, but it sure is fun getting the old girl up and running again.
Thanks to all who responded. KD

Just remember that the 1907 Browning is a blowback pistol, the original cartridge genberates pressures in between the .380acp and the 9x19....

9x19 loads could be disastrous in this pistol....

For years I loaded my trimmed .38 super cases with 4.3-4.5grs of Unique, works fine.

Thanks John,
The load that I'm thinking of with 3.5gr of W231 would be fine using the 90gr XTP bullets then.
I'm not looking for powerhouse loads, just something relatively accurate that will be kind to the old girl. KD

As I said earlier, I use 9mm Luger (9X19) starting loads. The 9mm Browning Long has about 10% more capacity than the 9X19, so pressure-wise you are talking lower than 9X19 starting (i.e. low 20K psi range). The M1903 Browning used a load rated at about 23,500 psi and fired a 110gr bullet at 1100 fps. http://www.vist.lt/klasika/brown03.php3

Look at this page.

http://stevespages.com/355p_4_124.html

That website (run by a CGN member) lists a huge array of loads for many bullet weights and powders, but also provides a range. Many load manuals only provide max loads, but these list starting loads as well. The loads listed are taken from published reliable sources and compiled together in one place. Useful stuff.

I have only loaded 125gr cast bullets over Unique, W231 and Bullseye, and I found the starting loads from those tables are mild for the 9mm Browning Long, but I have not ventured more than 10% higher (e.g. if starting load is 4.0 grs, I'd go no higher than 4.4 grs). With those loads, your sanity check is that you should not be exceeding 1100 fps with bullets heavier than 110grs (the original loading), or to use loads whose pressure is listed as higher than 23K psi for the 9X19.

Excellent site, thank you! KD
