SAAMI is all about chamber and brass dimensions, and has nothing to do with powder charges or performance standards.
Anyone shot tula brass max? WW has some in 45 auto and 40sw. Never seen it before
You are confusing cartridge case vs bullet jacket.colonel kernel From the test, it seems basically that steel cases are ok but they will wear your barrel out in less than half the time it would take for brass to.
well according to the tests from lucky gunner it will only do it for half as long before the barrel is rendered unusableAny decent AK or SKS will shoot steel cased ammo all day long and beg for more
He's thinking of steel jacketed bullets and not casings. Almost everyone who makes 7.62x39 makes steel cased ammo. I doubt that would be the case if it wore out guns after a couple hundred rounds.well according to the tests from lucky gunner it will only do it for half as long before the barrel is rendered unusable
Keep in mind how the luckgunner guys were shooting. They shot these guns hot. Really stinking hot. They mention their mag-dumping habits several times in the article. An excerpt:well according to the tests from lucky gunner it will only do it for half as long before the barrel is rendered unusable
If anything would make that lacquer coating “melt,” it would be the treatment these rifles received during the test. We shot them until they were too hot to hold – hot enough that a chambered round would cook off in ten to fifteen seconds. We also tried leaving rounds chambered before temperatures reached that point. None of this harsh treatment caused extraction problems.
Since the Tulamo chambers in your other gun my guess is the DB9 chamber is a little tight. If you have a good micrometer or worst case use a vernier caliper you could take some case measurments and compare to the SAAMI specification.Bought Tulammo Brass Max 9mm 115 FMJ Brass Case and it won't fit in my DB9 https://www.youtube.com/watch?v=XILA00a3Mt8
