Buy one box of those bullets and see if they work. That's a lot less costly then rebarreling your rifle. Your 1:10 twist, if that's what it is, isn't far off the common 1:9 or 1:9.5 twist used for 7 mm cartridges of any version by most makers.
Savage used to use a 1:11.5 twist on their 7mm-08 barrels and it was indeed marginal for anything over about 140 grains but give your barrel a try first.
