2 trips to the range with both guns. First trip was Flawless shooting about 60rds total each gun half tulammo and s&p ammo.
2nd trip was close to flawless. Wifes gun shot 95 rounds flawless. i shot 90 rounds no problem. but when it got to the last 5 tula ammo i had, it had one ftf (cleared mag and reloaded)and then one ftl and it jammed on the 4th rd..........
Not sure what happened i didn't clean the guns after the first trip on purpose as i really wanted to run about 300rds each before cleaning to see how it reacts. My guess right now is ammo or break in period (im no expert)
I did clean it when i got home but i will run another 100 rds of the tula and some other ammo next week to see how she does.....
I've had a few of my pistols choke on Tulammo that have otherwise been flawless on brass cased rounds. However my Sigma 40VE has never had an issue with it. But, I really haven't shot more than maybe 100 rounds of the Tulammo through it. The steel cases don't slide together well like brass, I was having failures to load in 9mm and 40S&W pistols. I was having a hell of a time loading the mags to full capacity with the Tulammo too. Tulammo is fine for plinking but I'd never rely on it to be used in a bad situation unless that's all that was available. Try a few different kinds of ammo for sure, some pistols just don't like certain brands.
