I would be cautious, as Ackley's load data tended to be VERY hot and none was pressure tested. Nor do you have any lab-tested load data with modern components to go by.
If the gun was shot alot, it is likely the throat and origin of rifling are shot out. Even if in good shape, you are on your own working up safe loads, depending upon the strength of the rifle, and how knowledgeable you are with QuickLoad or other software.
Unless you are a very experienced and knowledgeable handloader, OR can get the rifle cheap enough to have it rebarreled and relined to a less complex cartridge to reload, I would let it pass. However, if really cheap, this might be a good candidate to send to JES to have rebored to 35/.30-30!
