Home Forums Hunting & Shooting AR and Tactical Rifles Powder issue

I went out this morning and brought a box of Fiocchi factory ammo and three handloads, fired 10 rounds, all ejected fine, first handload 24.4 gr H 335 55 gr fmj, fired 10 rounds, one failed to eject. next handload 25.5 gr A2520 69 gr Sierra tmk, fired 10 rounds, two failed to eject, fired 10 rounds of same bullet loaded with 25.5 gr Alliant power pro 2000, two rounds failed to eject. one thing I did notice is that the H 335 ejected the cases a little farther than the other loads, however I did notice that the ejection pattern with all loads was different. The cases ejected at different angles, example the Fiocchi ammo, first two rounds ejected at 2:30, third and fourth rounds ejected at 4:00, fifth round back at 2:30. I am going to take the BCG out of my other AR and use it to shoot the same loads that I shot today, if they all shoot fine and ejection pattern is the same then I am assuming the extractor or maybe the gas tube may be causing the problem, don't think it's the lower.

Gas tube would be the last place I'd look. of course that means with my luck, the gas tube is the issue.

I'd still question the placement of the gas block...

Went to Reno gun show talk to the guy that built the upper, he was not there but a friend of his was, told him the situation, had the bolt with me, he took it apart and replaced the extractor, it works much better, shoots every load that I tried but still has issues with loads with A2520 powder. That particular load shoots groups under 3 inches at 400 yards and is just under max, may carefully increase the powder charge but hate to mess with an accurate load.
