I like the cost and general reliability of the Wolf ammo. Sure it is dirty powdered, but I grew up with black powder so I manage. I had read of some varmint hunters having the sealant shellac on the shell case melt and cause the cartridge to fuze into the chamber under hot, repeated shooting with the Wolf ammo using single shot Thompson contenders.
Two Summers ago I was doing extensive shooting of Wolf .223 in my Savage bolt action and ignored the increase in shell resistance to extraction. Then the bolt froze and after a good yank, the shell remained glued into my rifle's chamber. I ruined a good cleaning rod having to hammer out the stuck shell case.
This year I tried some more Wolf .223 in my new CZ 527 rifle. Remembering what happened before I was careful to watch the heat buildup and any resistance with the extraction of the bolt. I noted that the case dimensions for each cartridge were inconsistant as sometimes the case would drag alittle in closing the bolt, and in other instances, upon extraction of the fired case. Other brands of Russian .223 did not have this resistance aspect with my CZ rifle, only Wolf. In both .223 rifles the accuracy of the Wolf brand was inferior to other brands tried.
Even my Romanian AK finds the Wolf to be inferior in accuracy compared to other brands. But in this rifle I think it is marginally acceptable and I buy it for casual shooting as the AK-47 seems to digest it ok and the price is right. My fellow shooters have warned me to keep the chamber clean as the shellac will build up and I risk tearing the shell head off. I plan to purchase a broken shell remover tool soon to be on the safe side.
I think Wolf brand ammo has its place, especially if you find it to be the most accurate brand for your rifle/pistol, etc., but use caution with heat buildup on the bolt and single shot actions. And if used on pistols, do clean them after 150-200 rounds or so:grin:
