I've got a Leupold Mk5 5-25 Illum. TMR coming soon--to go on my lightweight 300PRC build. Current street prices are pretty good right now also. I compared the 3.8-18 and 5-25, and prefer the 5-25 for a long range bolt gun. It's not much heavier, and the image was superior at 15-18x, where I do a lot of my shooting. Every scope I've used, including my S&B 5-25, have the best optics well short of their max magnification.
