My views are that the Hirtenberger surplus is very consistent. COAL lengths are always the same. Bullet weights are always the same. It seems to shoot almost always the same. It is great stuff. It won't harm "target" barrels. My only gripe is the bullet weight is low. At 147gr, and the further you get out distance wise, the more it's affected by the wind. I've shot it out of everything from an M1A to my PGW Coyote to my Modern Hunter to my CZ hunting rifle to my custom BR with a Jury Custom barrel.
And you can't beat the price!!
