for those who wanted to know here is some update on this project. I just fired it a few times after receiving new 7.62x25 barrel from Barry. Although it took a while, barrel is made to my specs and installation was a breeze. Magazine and trigger linkage modifications were done months ago. Pictures are crappy because I am back to using my cellphone as a camera.
here is how it looks like, nothing special from outside, just another Beretta Storm
view of lower with magazine inserted
same view with ammo in a magazine (factory surplus ball ammo)
picture of surplus ammo beside my own roll of 85gr over 14.5gr of H110.
Test firing went ok, no problems whatsoever except for a slight feeding issue. Tokarev grip angle is diferent and therefore ammo is sitting with slight nose down angle and does get caught on a shoulder of bottleneck chamber. You can see it on this picture
I am thinking about adopting some double-stack magazine made for 38 super with rake angle close to beretta's. If anyone can make a suggestion it will be highly appreciated.
Chronograph tests show surplus ammo flying at 1950-2040 fps with average being around 2000 fps. Accuracy acceptable considering Storm's crappy iron sights. My ammo is 2150 fps on average, fluctuating from 1120fps to 1180 fps although accuracy is a bit worse that factory surplus.
If anybody knows of a good (or any) source of 85-88 grain bullets in 7.62mm diameter please let me know because I am running out of stock.
