Several things to keep in mind with this rifle:
1. It has a twist rate of 1/9". This means it will be better suited for 62grain ammo than 55grain. 55grain will work and is fine for casual shooting, but 62grain is better. Finding 62grain in bulk shouldn't be a problem.
2. Find out how this rifle is chambered. It states it is chambered for .223. Some manufacturers will use .223 and 5.56 interchangeably, as do some ammo manufacturers. But, if it is a true .223 chamber, shooting 5.56 ammo in it can cause overpressure issues. And, if it is a match .223 chamber (i.e. tight), this can be more of an issue. (You will have the same issue between a true .308 chamber and 7.62 ammo.)
3. Wolf and other Russion ammo is usually laquered and steel cased. The laquer can build up in the chamber as you shoot more and cause extraction issues.

it is written for AR15s, but the information regarding headspace applies to any .223 vs. 5.56 discussion.
