Tula’s 7.62x39 cartridge keeps its qualities under various climatic and weather conditions, independent of the season and at a temperature from –50 to +50 Celsius.
The cartridge complies with CIP requirements and is settled upon chambering until the case shoulder rests against the chamber cone.
Tula runs acceptance tests of cartridges by deploying the Ruger Mini 30 and SKS.
The Tulammo is garbage! I dont like to bash or put down any vendor, supplier or manufacturer...however I am VERY disatissified with the Tula brand ammo in 7.62x39mm caliber. 10% of ammo did not fire at all! A soft primer strike on 10 rds out of a 100 rd box. The remaining ammunition was not only faulty, as it sizzled n fizzed prior to exiting the chamber & barrel with a 1 or 2 second DELAY IN FIRING ...VERY DANGEROUS!!! And as if that wasnt enough, the muzzle velocities were inconsistent each time I shot...some velocities ranged from 1149fps to 2314fps WOW!!! I feel the ammo is to old or very old n must have been stored for a long period in a damp environment possibly. A sealed cartridge and primer is a much better choice here...like the Wolf Military Classic or WPA polyformace...or my favorite the Barnual laquer coated cartridge AND primer consistently shooting velocities at 2480fps CONSISTENTLY AROUND 2500 FPS EVERYTIME! VERY DISPLEASED WITH TULAMMO AND WILL NEVER PURCHASE AGAIN...TO MANY INVONSISTENCIES...I WILL STICK WITH THE BARNAUL BRAND...OR BROWN BEAR AMMOS...
I have fired thousands of rounds of Tula Ammo and misfires are extremely rare.
