Is there any difference between the Wolf Polyformance and the WPA Military Classic .223? I have heard that the MC is loaded hotter, but I wanted to find out for sure.

| Both are teh same power. The WPA is polymer coated vs the military classic which is varnished. The poly came of age a few years ago when people with AR's and other quality weapons had problems with the shelack coating melting off in hot chambers and leaving a coating which built up and caused malfunctions. (Beats me why AK47's and SKS's can fire that stuff you 20 years and not have a problem. The poly coating does not cause any build up. |

I have some WPA Polyformance on the way, and some WPA Military Classic and Brown Bear to compare it to (all 55gr FMJ)
The key difference is surely the coating (Polyformance is polymer coated instead of lacquer coated) though apparently Wolf can be made at either Tula or Barnaul (Bear) depending on the product line. I will definitely be interested to see if the Polyformance is Barnaul since supposedly it is slightly higher quality than Tula. |

Both are polymer coated. Poly has a boxer primer and MC has a Berdan primer. Not sure which is a better primer. Thats about the only difference. The Polyformance is "factory" new ammo (?). Both have the same velocity. I have both at home, but I have not compared them yet.
Polyformance (55g) is 3241fps & 62g is 3025fps. http://www.wolfammo.com/index.php?option=com_content&task=view&id=76&Itemid=115 MC (55g) is 3241 fps. http://www.wolfammo.com/index.php?option=com_content&task=view&id=77&Itemid=116 Google that shit son...knowledge is power (its also half the battle if you ask GI Joe)! 
ETA: Boxer primers use one flash hole to ignite the powder. Berdan primers use two flash holes to ignite the powder. Ammo with boxer primers is easier to reload. Since we're talking about steel case, you won't be reloading. Google...its a wonderful thing!! |

I reload steel all the time, works great.Also the wpa ammo is slower out of my ar than regular wolf by quite a bit, 100 to 150 fps slower, both 55 gr. http://www.wolfammo.com/index.php?option=com_content&task=view&id=76&Itemid=115 MC (55g) is 3241 fps. http://www.wolfammo.com/index.php?option=com_content&task=view&id=77&Itemid=116 Google that shit son...knowledge is power (its also half the battle if you ask GI Joe)!

I don't reload, but I heard steel can be a bit brittle for reloading. As for velocity, I'm just listing what Wolf's website says. real world velocities are good. Thanks. |

I picked up 1000 rnds from aimsurplus of Wolf Poly 55gr .223
chrono-ed a 10 shot group: avg was 3123fps out of 16" 1 in 7 PSA barrel watch chrono video I didn't have any WPA with me that day to test; but have shot before and it impacts about the same as Wolf Poly 55gr |

I just wanted to follow up –– my shipment of WPA Polyformance 55gr came in last week. It looks exactly like the WPA Military Classic, same case coating / color and same head stamp (Barnaul factory, same as Bear). I don't have equipment for measuring velocity but I'm guessing if there is a difference between them it's probably that the WPA Poly has more / different powder compared to the WPA Military Classic.
I didn't get to shoot too much due to thunder storms when I was at the range but if it's anything like the Brown Bear I've been shooting for a while it should be GTG. |

I have read several forums about the different characteristics of steel VS brass cases. I have a couple of questions that I am hoping someone can help me with.
Has anyone compared the effect that the poloy coating has on the steel, as in would the poly coating expand itself when heated to help seal the bore? I have heard a lot about steel wearing more than brass even though it is softer steel than the bolt and extractor are made from. Because the polymer coats the steel, does it in anyway act as a cushion between the case and gun parts? I could not find this in a search so apologize if it has been covered before. cheer, Tom |

All I can tell you about Wolf Polyformance and the WPA Military Classic is that my Colt short strokes them just enough to not stay open on the last round (sometimes), probably due to the heavier buffer spring Colt puts in some of their guns.
Wolf works great in my home built, probably because it has a standard buffer spring. I chrono'ed 10 of the 55 grain .223 WPA, they averaged 2997 fps at 75 degrees, they had an extreme spread of 526 fps. The slowest was 2591fps and the fastest was 3117fps. |
