Yugoslav ammo vs Wolf -- test results
Yesterday I wanted to test different types of ammo to see which is more accurate. I tested some Wolf Military Classic and some Yugoslavian milsurp ammo stamped 1984. I bought the Yugoslav ammo from Aim Surplus. Using the same rifle, I shot 10-shot groups for both types of ammo. I kept everything as controlled as I could...sandbags, slow shooting, etc. I suspected that the Yugo ammo was going to be more accurate, but I didn't realize how much more accurate than Wolf it really is. I was using a WASR-10/63 rifle with 4x scope on a 93-degree sunny day.
At 50 yards
Extreme spread: 5.375"
Mean radius: 1.33"
Extreme spread: 2.25"
Mean radius: 0.64"
The Yugoslav ammo is much more accurate, and is about the same price as Wolf. The only drawback to it is that it has a corrosive primer salt that makes it necessary to clean the rifle right away after shooting. I use a spray bottle to flush the gas tube and barrel with water after I shoot.
Thanks for the report as I haven't bought Wolf since it was $74 oer 1K. Don't over stress on the corrosive. Just think of all the X39 rifles is service today and over time that have rarely if ever seen a cleaning. Chrome barrels and hard gas piston parts are also your friend.
Do you have another rifle as a test bed? One rifle does validate your test.
Each barrel has it's own harmonics and the test does not mean that Yugo will shoot better consistently in other rifles.
I know you probably don't have one, I don't, but I would like to see chrony results between the 2. Just shooting the Yugo, I know it's hotter. Would like to know HOW MUCH hotter....
If it turns out that one of my friends has a chronograph, I'll do a test.
I have a shitload of Wolf to blast through before I'll ever need 7.62x39, but still interested in the outcome.
If the Yugo turns out a lot hotter and a lot more accurate, I may switch and keep a bottle of water handy for field usage.
