I think you handled mine many years ago, BUM. It was a pre-war, four digit Model 70 in 270 Win.
When I got it, it was so abused and neglected that it appeared hopeless, The bore and chamber were both rusted so bad they looked like old concrete. But, we know better than what first appears.
The rebore completely cleaned up both the bore and the chamber, and the rifle immediately began printing inch and a half groups with the first loads, 286gr Norma Dual Core at a tad over 2400 fps. The rebore demanded the rest of the rifle to be resurrected.
All metal parts were cleaned up with 000 steel wool and automatic transmission fluid, rinsed clean with detergent, then cold blued. Stock was cleaned up with dish soap and hot water, followed with several applications of boiled linseed oil and much elbow grease.
All done and put back together it has been carried many thousand of miles on foot, in airplanes, boats, and snowmobiles. It functions perfectly and not one time ever missed a beat. Could have sold it many times, but it’s still family.
My point in telling the story is that you may have more than what you think, so why not give it a try?
