I don't know how recently you bought your rifle but I will offer this tidbit:
If your rifle is really new <50rnds, make sure it's very clean to start with & monitor your grouping.
Why? Because factory bores are somewhat rough, some rediculously rough, some quite good (kind of a crap shoot). As the jackets of the Barnes are softer than conventional bullets, there is a possibility of excessive fouling until your barrel is "broken in" (read smoothed out). As far a stating that it needs to be REALLY clean before use, just as noted with the jacket hardness, if conventional bullets have been fired, then Barnes have been fired, there is an almost guaranteed example of extreme fouling (I sometime wonder is this isn't why Barnes gets a bad wrap for fouling) Other than those two cardinal rules, enjoy your hunt, you have all the bullet you're going to need.
