I’m putting together a middy and would like it to shoot cheap Wolf steel cased ammo reliably. From what I’ve been able to gather there are two main problems that folks are experiencing when using this ammo: failure to extract and short stroking. I know these two problems aren’t exclusive to the steel cased ammo but they do seem to be more common.
Perhaps the extraction problems are caused by insufficient obturation of the steel case which leads to a faster and higher rate of chamber fouling. So cleaning the chamber more often might be an easy and obvious solution. What other considerations should be given specifically to the extractor when shooting steel?
Regarding short stroking, I think a standard carbine buffer is the way to go, and I have a standard $4 carbine buffer spring, made by CMMG, measuring 11"… Any special considerations for the buffer spring?
What am I missing, why are there so many who claim to have problems with Wolf ammo?
I have a BCM middy, BCM Auto BCG, H Buffer. I shot about 80 rounds of wolf the other day and had no malfunctions. Sticking with a carbine buffer would lower changes of short stroke.
Just run the middy the way that it comes from BCM. Plenty of guys are running it with wolf with out problems straight out of the box. Use the carbine buffer and standard buffer spring.
I agree with the others. You shouldn’t have to do anything. I’m using a BCM middy and have over 500 rounds of just wolf through it without any problems. Using BCM everything - receiver extension, buffer spring, H buffer, BCG, etc.
When i owned my BCM middies i ran them with H buffers.
Im currently running my Noveske Recce with an H buffer as well and between the three uppers i have well over 4k rounds of wolf through them all. Not a single stuck case. I am by no means saying it cannot happen but if you have a proper spec chamber, keep it RELATIVELY clean and lube the snot out of the rifle you shouldnt run into any issues.
Yes its dirty, yes stuck cases happen but its worth it, at least to me to be able to run cheaper ammo.
I use a carbine buffer and Colt carbine buffer spring in most of my mid-lengths.
I have shot a few hundred rounds of Wolf through a couple different Noveske mid-lengths without any issue, I had an older Sabre Defense 1/9" twist mid-lenght that would reliably shoot Wolf ammo, and another student put approxiamtely 1,000 rounds of Wolf through one of my BCM mid-lengths in a 2 day carbine course a few months ago. The only issue was one of the Wolf casings got stuck in the chamber at the end of the day on training day 2.
The BCM mid-length had been through another carbine course and some other training and recreational shooting without being cleaned (approximately 3,500 rounds) before it was used in the LMS carbine course. The gun was not cleaned and another student used it during the entire class shooting Wolf (approximately 1,000 rounds) and was not cleaned. So the gun went uncleaned for approximately 4,500 rounds (1,000 of that Wolf) before a spent Wolf casing got stuck in the chamber. The gun had no other issues (ie. short stroking, etc). Over the years, I have seen quite a few Wolf casings get stuck in the chamber of AR’s.
