Loading for just one rifle, you do not need to full length resize, just neck resize. It makes your brass last longer.
If you want blasting ammo for your Model 71, you could load cast bullets for it.
You could also take .358 jacketed bullets and run them through a Lee sizer, (lubricated) to reduce them to .348. It is not difficult to swage jacketed bullets down that much with an ordinary reloading press using the Lee sizer die. You start with a .339 lube/sizer and open the die up to the diameter you need, testing bullets as you get close. Lee will make you a custom die for only a few dollars more than the standard kit. $38 for a custom kit.

It is kind of an advanced technique for a beginner, but it works well and is not expensive.
Here is an article on the Model 71 and the .348 Winchester.
