Concur... to a degree. While the older Wolf lacquer would melt off and cake to chamber walls, so much so that cases could get stuck and get ripped apart during extraction, that problem has diminished greatly since their polymer stuff came out. I've only recently started feeding my AR Wolf, and only because of the ammo price spike -- used to be, it wasn't the cheapest. For a normal range day or even a day at a rifle course, you'll be fine. Clean it after you shoot it and there's no need to worry.
Your average AR will not stand up to the same abuse I've put my AK through (obviously). Now, I wouldn't trust my life to Wolf if I had a choice, but if people are avoiding Wolf b/c they think it won't function in their gun, well, their gun is the weak link there.
ps- this doesn't apply to all Wolf brand ammo, only the steel case stuff. Wolf Gold is just as good as your average Rem/Win/Etc mid-grade ammo.
OK, I'll be a dolt and ask what are M193, M855, and M262/2? I was expecting you had powers/weights/bullet combos for reloading. Don't blame you for not posting those if you have them just PM me.
Those are your Muzzle Velocities and Ballistic Coefficients.
M855 is the green tip tungsten penetrator round. The most common 5.56 bullet in military service. Its weight: 62 grains.
M193 is 55 grain, ball. Pretty much the second most common round.
MK262 is a 77 grain Sierra Match King. The MOD1 is with cannalure, hence the change in BC.
You are running a right hand twist, 1/9 at 14.5" so these numbers are as precise as you can get. Its a good starting point for your dope log. I assumed you didnt have a chrono. You dont need to experiment at all now. These were the three best performers for your rifle specs. (TAP 62 grain was omitted)
The BC and MV your rifle will get from the MK262 is obviously FAR superior to the other two bullets.
If you want to exactly replicate the powder load of the 262, I can see if we have the tolerances here somewhere. I'll PM you if/when I find it Sir.

Ahhh, that clears it up. If you find the data I'd appreciate. I do have a Beta Master Chrony and it goes to darn near every range trip.
I can't comment on the lacquer vs polymer Wolf ammo, but steel cases have another method of making a mess in your gun. A brass case is softer than steel, so when the charge fires, the case expands ever so slightly against the chamber walls, sealing them. A steel case does not. As a result, steel case ammo allows gases to seep between the case and chamber wall, dirtying up the chamber walls. So if you shoot a bunch of steel case ammo, then switch to brass without cleaning first, you get stuck cases, FTE, etc.

Within that long article is a link or two to Mk262 specific ballistics and performance.

Here is a very good external ballistics calculator.
And Crane's PPT on MK262

This is a great tool when selecting ammo. Terminal performance on the 5.56 Mk262 and 6.8 SPC are about as good as it gets.
