Regarding your mangled brass...Did it look like this:

These were from my Para conversion. A little more extractor tension fixed this issue.

denclaste, would you mind slugging the bore of your 10MM for me?

denclaste · January 04 2013 12:24:57 PM MST

SQLBULLET: YES just like that. It hasnt done it again since I installed the 20# recoil spring. But since the gun only has 180 rounds on it I dont consider it a big prblem. Will check and adjust tension as needed. Thank you.

Steve: I dont have the equip to slug a barrel BUT I will have my longrange rifle barrel maker look at it and measure it or slug it. I'll be at his shop on the 9th and will let you know then what groove/land measurements are. It does appear to copper foul quickly ( but I'm use to hand lapped cut rifle barrels so dont have much experience with other types).

Thanks!

Steve,
Had my barrel maker examine the barrel today. He said the bore was 0.391" and the grooves measured at 0.4024". He said it felt and looked like "saw tooth" rifling and the lands and grooves looked about equal distance across. Hope this helps you. He said it wasnt competion quality (his barrels have set US and world records in longrange rifle shooting) but it certainly was "good enough to get the job done". So far I'm up to 300 rounds and the copper fouling is nowhere near as bad as it was at the start.

Thanks.
That .4024 is still over-sized. Should be .400. Shooting Lead .401 bullets out of your .4024 barrel would surely cause some serious leading.
IMO they have a problem with the barrel and Groove diameters.

Those barrels may be OK for jacketed bullets, but I really doubt they would work for lead, and would definitely merit replacement IMHO. This is kinda a deal killer for this gun for me. By the time I buy the base gun for $600, add a barrel for about $200 and account for my time to fit the barrel or the expense of paying to have it fitted, I am solidly in Delta Elite price ranges and the occasional Kimber.

Too bad really. An otherwise solid option spoiled by poor QC in the barrel.

${$default_angry_smiley}$ Ok... this thread just ruined my Friday! You wake up fantasizing about a hot new "10," and by the time lunch hits, you realize you're looking at an oversized slag!

Steve4102 · February 01 2013 08:11:11 PM MST

Sorry!

Have any of the owners gotten Armscor to replace the barrel, and if so was the new one any better. If they address the horribly out of spec barrel, then this would suddenly become a solid gun for the money.

I called Sean a Smith at Armscor last week. He told me a month or so ago that new guns and "Parts" were due to arrive in mid January. January is over and the parts and guns have not yet arrived. He assured me that as soon as the new barrels came in, he would give me a call and issue a "call tag" for shipping my pistol back to them.

He now says ETA for guns and parts is anybodies guess.

I just benched my RIA and Glock 20 w/SL aftermarket barrel to see if the oversized barrel was a problem. With 200gr jacketed bullets the 20 shot groups at 25yrd were within 0.112" of each other. This was done at our indoor range so no wind to contend with and it was comfortable inside(outside here is 9*). New starline brass in both, same load, same OAL,same primers. Perhaps I cant shoot well enough to cause a signifigant difference. I'll try again with 3 experienced shooters doing it when I can arrange range time. For now ,since I never shoot lead, it seems to work ok.

Yeah...All I shoot is lead so a barrel that over-sized is definitely a problem.
