Savage 111 Trophy Caliber Change / Rebarrel

Good Morning to all,

I have a few questions for everyone. I found a smoking deal on a 9 month old Savage 111 Trophy Hunter in .270 Winchester, needless to say I picked it up right away. Now comes my dilemma, I already have a .270, but I do not have a .300 Win Mag or a .338 lapua. I would like to change calibers from the .270 Win to .300 win mag or maybe .338 lapua (I'm not sure the lapua is even possible can someone verify?) The way I understand it, I can achieve this by simply re-barreling appropriately and changing the bolt head to accommodate the new caliber. I have in fact verified that I have the long action and that I have the 1-1/16-20 Barrel Shank. Am I missing anything in the process here? Also, can anyone recommend a parts source for me? Ultimately I plan to place the barrel and the action into a nice stock and make this a long range hunting/entry level competition rifle. I appreciate everyone's input!
Thanks in advance,
Ryan
