I have a fluted #3 Lilja @ 23 in a Classic Edge & aluminum PTG Oberndorf b/m. Rifle only sans scope & rings is 6 lbs 4 ozs for a .243. So figuring the standard fill stock should add about 6-8 ozs maybe and a couple for a LA and you should still be a little less than 7 lbs I think you should be fine.
