Many years ago I picked up a T-38. Had a headspace problem because of non matching bolt. Rifle appeared to be in excelent shape with sharp rifling and no rust. Mum was ground off. Ammo was available for it from Norma but they wanted an arm an leg for it. I re reamed for 6.5x308. I got a set of dies from RCBS, picked up some LC brass and reloaded. Had the rifle completed about 6 mos or so and guess what.............Remington released the 260. BTW......barrel is now stamped 6.5x308. Did some stock work and gave to my daughter for deer rifle. She loves it.
No such thing as a stupid question. What is stupid is not asking it.
