Vulcanizer,
What ya have is what is more commonly known in general terms as "Santa Barbera" ammo.
I have a couple cases left from 2 years ago when it was cheap.
Here's the skinny.
Good ammo for the most part. Definately safe to shoot.
Accuracy is NOT quite as good as LC M855 in most rifles, though some are the odd kid who actually likes eating Brussel sprouts.
Problems.
Weak case rims have been a very common complaint with some lots of Santa Barbera.
The extractor literally tries to pull the spent casing from the chamber, the case rim fails, or partially fails, and a double feed results.
Have had this happen several times with SB 62gr ammo in several different platforms, and under varying conditions.
Potential issues if you care.
The SB 62gr projectile is NOT the same as the US M855 and does NOT act like M855 in impact.
In short, I'm to the point of occaisionally remembering the SB stash and burning it up when I remember it's there for short range practice on paper targets, and general movement while firing drills.
It's almost like having a buddy load a couple of dummy rounds in your mag for practicing malfunction drills.
Devils advocate statement.
While general concensus of the SB has been poor in nature, some folks have gotten lucky with "Good lots" of SB, and have had no problems.
Murphy hates my Guts and is quite malicious about reminding me, that I ain't one of the lucky ones.
I hope that you are.
If not, remember the proper drill.
Tap the mag, pull the charging handle to the rear, observe the chamber, Notice the double feed while moving to cover(Or getting lower into it), lock the bolt to the rear, Forcibly remove the mag, clear the action, dry cycle 2-3 times to get the spent case out if possible, reinsert mag, release bolt and press on!!!
I really hope you got a good lot.
If it wasn't for the rim failures, this stuff would be excellent practice ammo!!!
Bets of luck!

P.S.
IN the world of Vulcanizing, does one have to marry into the title of "Lord" or is it granted by the almighty alchemy dept?
