Not knowing what loads the $85 and $25 rounds are, that is a hard question to answer. My gut feeling is that the high priced stuff has an expanding bullet, Nosler or similar, while the cheaper stuff might be ball.

The best thing about reloading is that you can tailor the rounds to your rifle. Every gun that I have ever owned had one particular load (that I loaded myself) that was more accurate than a similar, but different in some way (probably powder charge) round. I would take my reloading gear to the range, make up some loads, fire them, look at the target, whip up another load with different powder, or different amount, fire that, etc etc etc...
