Olympic Arms Comments on Wolf Ammo
Here is exactly what Olympic Arms (maker of AR-15's) says about Wolf ammo on their website. Draw your own conclusions about it:
Ammunition Warning
This warning comes based on an increased volume of customer calls regarding feeding and ejection malfunctions of AR-15 style rifles. Further investigation of these situations came to prove that the vast majority of these malfunctions were based on ammunition, and not the firearm itself. Following is some of the information that have compiled based on this investigation.
Lacquer Coated Ammo
If you plan on using lacquer-coated ammo in your Olympic Arms AR-15, please be aware of the following. We have received many recent phone calls, as well as some rifles sent in for repair, complaining about reliability problems in their Oly Arms AR's. The first question usually asked is, "What ammunition are you using?" The answers to the question, as well as seeing the chambers of the rifles that were sent in are showing us that lacquer coated ammo is clogging the chambers badly.
What we are seeing is that once the chamber in the rifles gets hot, it is melting the lacquer off of the casings, and leaving a gelatinous goo in your chamber. Under continuous fire, this is usually not noticed, but once you stop, the barrel cools, the lacquer sets and you now cannot chamber and/or properly extract your ammunition. You will experience this in AR-15's much more frequently than other rifles such as the SKS and AK/MAC variants. In most cases the 7.62x39 rifles have chambers cut to the large end of the safety spectrum so that feeding and reliability is uncompromised by the type of ammunition or the consistency of the case dimensions. AR style rifles, and especially those from Oly Arms will have tighter chambers so that you can experience a greater level of accuracy that these rifles are capable of performing. Olympic chambers specifically are cut to 5.56 NATO specs via Clymer reamers in all button rifled barrels, and minimum SAAMI spec .223 Remington on all SUM Ultramatch barrels. Our rifles will provide superior accuracy, partly based on that fact.
Major brands of lacquer coated ammo we have seen are Wolf, most Russian ammo (even if it has the Remington head stamp), Norinco (or most Chinese) and most all former eastern block countries.
Our recommendations: DO NOT USE LACQUER COATED AMMO. Otherwise, be prepared for the consequences. Additionally, most lacquer-coated ammo utilizes steel cases instead of brass. BAD FOR YOUR CHAMBER.
The Consequences: Poor feeding, poor extraction, poor accuracy, and an impossible to clean chamber possibly resulting in a rifle that simply does not work.
Although Olympic Arms only warrants their firearms when used with new production brass cased US manufactured ammo, we would be remiss to think that the bulk of our customers do not use remanufactured, imported or reloaded ammo. We know that they will, and do. The reason that our warranty does not cover the use of this ammo is as much to protect you, as it is our product and our product. If you are using factory US new manufactured brass cased ammo, and something goes wrong and the rifle is damaged, the ammo manufacturer will usually take care of any repair costs. If not, and the damage can be proven to be the fault of the ammo, you have some sort of course of action you can take against that manufacturer to recover some or all of the expenses of the repairs. If you use foreign lacquer coated ammo as an example, you have NO options.
Is your rifle worth it?
