Tulammo issues
 
Got a question. I have a bushmaster predator 20" barrel. Shot Remington ammo with no issues. Tried to shoot tulammo brand and through it and would not cycle and had a very hard time getting bolt and charging handle back. I've shot this ammo in many other calibers with no issues. Anyone else had this issue???

I put about 2,000 rounds of 55gr and 62gr TulAmmo thru my rifle, and only had an issue with the case sticking in the chamber (causing the charging handle and BCG to be extremely hard to pull back) when I ran it with no cleaning to see how many rounds it would take to cause a malfunction. Not meant as an insult but when was the last time you really cleaned the chamber.

Agreed, only pushed it that far because I've got limited experience with the AR and thought it would be good to know the limits of my rifle.

Freshly cleaned gun. Gun has only had 30 rounds through it prior then cleaned afterwards then 5 other brand then started on the tulammo i dont know. Maybe this guns gonna be picky

Gas tube might be out of alignment, causing some of the gas to leak out.

But it shoots the Remington's just fine but will check into the gas tube alignment

There are a few things that can cause cycling issues: worn bolt rings, (I replace mine every time I go to the range. You can get them really cheap if you buy in bulk at Brownells) buffer, cleaning-too little or too much, worn disconnector spring, and really rare is a bad batch of ammo, regardless of what brand. If I have multiple fail to cycle, I look at the firearm first. Also, you may want to look at the extractor spring. I usually replace it every thousand rounds. The reason I avise people to look at the gas tube is it is really easy to get it out of alignment if the teeth on the barrel nut aren't perfectly centered, as a tooth might end up pushing the gas tube to one side or another a tiny bit, and over time the tube is bent into the shape it is pushed, so some of the gas ends up escaping. I got lucky enough to watch a barrel being installed at the Colt factory once, and the tools they have to install the barrel to prevent this from happening are amazing, and not cheap either. Anyway, enough of my rambling:p Once you get to know your rifle better, troubleshooting it will become second nature to you. Start with the gas system, and work your way out from there.

Is it short stroking or are the cases are sticking in the chamber. Or both?

bushmaster74 09-20-2012 11:58 PM

The way it looks the casings are getting stuck in the chamber and I have to yank the charging handle back very hard to extract then the next round does the same thing.
