Thnx, I stopped using the Tullamo 308/762 on my POF 308 it chipped the bolt and did not cycle until I replaced it, On the 223 ammo I will test it this Sunday with my Ar15, I grabbed a 1000 rounds by mistake last time I was at a Gunshow :=( If it starts giving problems I probably just give it away to the next guy on the shooting bench from me...

I have shot hundreds of rounds of Tula through a G36K postie (video in the DT section and on my YouTube page) without issue. In my 416 1.4" postie however, the last round BHO would occasionally fail due to it having a bit weaker charge.

What range Sunday?
I ran 300 rounds last weekend. Not a single issue.

Thanks for the info. Would it be possible to elaborate on the issue and what design features cause the G36 to do better with steel cased ammo compared to your 416? From what I heard from G3 kurz, the G36 was tested to fire a wider variety of ammo than the HK416.

Could be that my 416 is a 10.4". Not sure if a 14.5" would experience the same issue.

Thanks for the clarification. Is the lack of the vent hole in the 10" guns most likely the cause of the issue? Thanks.
Just the opposite. The 10.4" guns do have not have the bleed-off hole so all the gas can be spent on cycling the action. More than likely the barrel is too short to get enough gas into the system thus weaker ammo will have issues.

actually, my G36 conversion WILL NOT cycle steel case (AT ALL). It appears to short stroke as each round manually loaded fires and ejects, but it WILL NOT pick up the next round. I have yet to hear a reason for this.
Have you tested to see if your carrier is dragging? Disassemble the gun and see if the carrier slides freely within the receiver. Other than that, you've got a barrel/gas system issue... Possibly a barrel that was cut too short or a gas block that was improperly moved or plugged. While I have never shot
Tula thought one of my own coversions, I have shot plenty of Wolf and other cheap ammo without issue.
