I spent the better part of a year buying used parts here and on sniper's hide, then sent the box of stuff to Travis (TMR) at RBros Rifles:
Rem 700, 243 AI, a Rock Creek fluted 1-7.5 twist, finished at 26", Manner�s stock, Badger bottom metal and mags. Gunkote finish, 20 MOA rail, Jewell trigger.
Made specifically to hurl 105 AMAX and 115 DTAC at the deer population.
More than a wee bit over your budget, but worth it.
