BTW: If you don't overheat your barrel, your standard mid-quality upper will last 6-10k rounds before accuracy degrades....

4150 barrels = 10-12k
Hammerforged = 12-15k
Nitrided = 20k PLUS

These figures strongly favor Wolf steel case ammo. Also, steel case is "weaker" and resents less strain and wear.

The only potential downside to steel case ammo:

1) Sticky extraction for non-chrome or nitrided chambers;
2) Increased extractor wear (these are CHEAP). I've never had one break, BTW.
3) Bi-metal jacketed bullets could theoretically increase barrel wear. HOWEVER, nitriding and chrome lining should negate this (if there is any scientific evidence to prove this happens).
Also, Federal (Lake City as in the provider of ammo to our military) is now using "bi-metal" jackets for "Nato" rifle ammo....


XM80CL = copper washed steel jacket.
XM80CL = full metal jacket.
XM80C = bi-metal jacket design.
XM80C = full metal jacket.
XM80CL = full metal jacket.
XM80CL = full metal jacket.
XM80CS = full metal jacket.
XM80CL = copper plated.
XM80CL = bi-metal jacket design.
XM80CS = full metal jacket.
XM80C = full metal jacket.
XM80CL = full metal jacket.
XM80CL = full metal jacket.

The "real" issue with Wolf steel case: its training ammo - not match or defense ammo if you want 1-1.5MOA capable fodder.

The repeated codes aren't a mistake. I think the duplicates are a result of Federal's multiple packaging facilities (one in Lake City, MO and one in Anoka, MN).

Gun Dog,
I wasn't knocking your choice. I have uses for "better" ammo too. I was pointing out to EVERYONE not to be afraid of steel case ammo.

I'm going to revise my 10,000 round number. I've shot 2,000rds in the past month...and have been shooting steel case since the early 1990's.

I've probably fired 10-15,000rds of steel case 223, and another 3,000rds of steel case 7.62x39mm.

I do always shoot brass case 7.62x51mm.

240v Mains Power (it's running at home now)

12v for vehicle (need to add a dedicate 6amp cable and relay as it will melt a lighter socket supply(I will add a switch as well on the dash)

Propane Gas in the bush (I get around 7 days from a 3kg bottle).

Well according to USPS tracking my GTI mini folder is supposed to be here tomorrow. I sure hope so Cause we got "THE" call that we are needed at the Grandkids Friday. That means we won't get home until around 7:00-7:15PM!

My reason for interest as well, not sure why the piston ARs don't like the steel cased.

It's underpowered. My POF has a Carbine buffer and runs fine. My LWRCs have H2 and fail to cycle. That tells me it's not getting enough gas (underpowered).

The POF also has E2 Extraction which probably helps.

There have been zero failures to extract or eject. Many failures to cycle enough to pick up another round.

I just ordered a Radical Firearms AR in 7.62x39.

For $500 it's already setup the way I want it for most part. I was planning on going with a PSA upper and lower but factor in the cost of the changes I would have to make and the RF rifle is the better deal.

My plan for now is to a SWFA 1-4x24 on it and see how it stacks up against my CZ527 as a hunting rifle.

That makes sense Arch and yeah thats what mine does as well just doesn't pick up another round. I wonder if it would be detrimental to put a lighter buffer in it.

Yeah for that price pretty hard to pass one up Lazi especially since you are already invested in the round.

Got a single mag carrier for my PX4 Saturday. Actually pretty neat. It's one piece of Kydex folded over and shaped (skeletonized). I will try and get up a pic in the next day or two. I think it's a pretty good deal for $15.00. It's thick Kydex so it should last.
