Team,
I've been thinking of ways to hi-cap out a Romanian PSL...and I may have a viable option...though I am sure to carry out it will take some metal work, on either the mag and/or the gun. To begin: According to my Lyman reloading manual, 7.62X54 has a rim diameter of .570 in, case length of 2.114 in, and overall cartridge length of 3.037 in. Accoording to the same manual, 303 British has a rim diameter of .540 in, case length of 2.222 and overall cartridge length of 3.075 in. Both these cartridges have been chambered in the same model of gun - the 1895 Winchester Lever action. So, as there is very little difference between the OAL of these two cartridges, it may be possible to develop a follower to convert a 303 British BREN gun mag to work in a PSL. Problems: 1. Bren guns were top fed, thus gravity assisted the feeding. Mag springs would have to be strengthened. 2. I don't know the machining needed to either the mag/rifle to make the mag fit 3. Mag would probably not work with bolt hold open Benefits: 1. If it can be made to work = 30 shot PSL! 2. Both mags have a forward lug and appear to lock in a spring catch at the rear. 3. Cartridges should be interchangable in the basic magazine body. If 303 Brit works in a BREN gun mag, 7.62X54 should...may need different follower and the strengthened spring to solve problem #1 above. Like I said...just an idea. I haven't seen a BREN mag in a few years and have nothing as a reference point. Who knows...it may work! |

I have mentioned this before and then was flamed out of hell. Beware.
Aparently the original designer hardly got this 10 rd mag to work so how can a peasant like you do what that man didnt. On top of that this is a marksman rifle and isnt meant to hold 30ish rounds. I have though of what this mag would look like. It would take a new definition of banana clip. |
The only problem with the mag concept is being that the rimmed cartridge needs to be staggered a certain way. The rim for the round above it always needs to be in front of the round below it. This will give it a / formation. The way the original mag solves this problem is sending it into almost a moon like shape. Now I am not totally positive. I think a magazine can be made to accommodate more than 10 rds in it. The only problem is that this angle would either be very severe would would be similar to a j obviously turned around. I need some assistance though. I need someone to give me the angle the round creates when it is stack up on another round. Save me alot of time with the guess work.

I seem to recall that Bren gun mags were used in other guns feeding Upwards instead of downwards. I don't think you would have to worry about feed issues due the a weak strength of the spring. BIGGER_HAMMER  i seen a pic of some people over in some middle east country that had a ak and in was made to fit the bren mags, i dont know what caliber it was chambered for though |

Well, here are some pics since I have both a BREN mag and a PSL. http://img149.imageshack.us/img149/2678/dscn5764fl8.jpg http://img149.imageshack.us/img149/9632/dscn5767hk6.jpg http://img149.imageshack.us/img149/3247/dscn5753vv3.jpg http://img149.imageshack.us/img149/7788/dscn5756pd5.jpg |
| Some Brens were converted to fire the 7.62x54R. I believe that they used the ZB-39 mag which is used for the 8x56R cartridge. I've tried putting 7.62x54R rounds into a Bren mag, and after 10 rounds the "pitch" of the magazine doesn't allow for the 54R rounds to seat properly. I have some ZB-39 mags and my curiousity is aroused. I'll have to check this out tomorrow. |

Very cool. I was going to suggest maybe trying ZB magazines. Looks like you're making some headway. As inspiration, if Hajab Jalalabab in his little village in Pakistan can do it, so can you: http://i134.photobucket.com/albums/q86/Blue_Falcon_One/Junk/dragmaggun-1.jpg WTF is that. Looks like 2 PSL mags welded on each other. |

It's two Russian Dragunov SVD magazines welded together. The clever gunsmith opted to make a "high speed," silenced AKM in 7.62x54R.
Check out that vented lower handguard - a TAPCO representative would be drooling over how to do that rifle's like but in crap-tastic plastic. |

Welding 30-40 $$ together doesnt sound worth it. |
