I know what you mean..My original HP rifle was a 40X in 308. Done shooting HP, went to some PRS, and local LR matches..pulled the 308 barrel, the third one of that cal. on the action, went to a 250AI for that shooting, worked well. Then I took a break from the comp stuff, and the rifle just sat in the safe for a few years.
Finally said "Hell", pulled er apart couple months ago...she now has a 7mm barrel and the 708 chamber. Working up loads as we speak..
BTB, I do also have a 5x57 on a 98 that I dearly love. That rifle has brung home lots of bacon.
Good Luck
