Compared to .17, .22 and most of the .24 calibers, yes, it will give you a bit more range depending on the bullet weights you use.
Me, I would use a 115gn Berger to get the most reach from this little jewel. This is based on my varminting experiences with the .243.
The 55, 65 and even 70gn pills do provide for some explosive hits out to 300-350yds, but the lighter bullets tended to drift a bit on me at ranges longer than that. I know most of the misses could have been eliminated had I took the wind into consideration more but I can't control myself, when that ground hog pops up there I gotta try 'em.
I was just shooting my .25-06 @ 700 yds earlier today. Had no problem ringing the 80lb gong. JohnnyK.
