I kinda went through the same ordeal with a ADL 700 in 270 win but it was all stock without a butchered barrel....what worked for me was ....first, free floating the barrel (most older wooden stocked 700's had a pressure point)....2nd, bedding the action....and 3rd, finding a load it liked.
It is now a consistant 3shot 1MOA rifle that shoots a very predictable pattern, the first cold bore shot is dead on, the second roughly about 1/2 inch higher and the third slightly lower than the first...it does the same pattern over and over when starting from a cold bore.
IMO, the OP should free float the barrel and bed the action before trying to find a load the rifle likes.....good luck and have fun!
