I wanted to post on the bore of my 95 year old Eddystone US Model of 1917 which is quite rough, but not as rough as it used to be.
I got this rifle from my dad 30 years ago and didn't think the barrel was quite as bad as it was. I used to check the bore by removing the bolt then looking through the chamber pointed at a light source or bright item such as a white piece of paper. Using that method I thought the bore was pretty good, it looked like a mirror.
It wasn't until a vigorous cleaning and a few pics with a digital camera that I was made aware of the true condition of my bore... Observe;
That was 1.5 years ago, after a 3 day cleaning marathon.
Either someone had thought they were getting the rifle clean, or just didn't care to. I am sure it had been shot using old corrosive ammo.
I didn't want to get too involved with expensive methods of trying to get the bore back into shape, I didn't actually have much faith in improving it to tell you the truth. So I decided to keep it clean and shoot it as I normally would.
Since I usually take one shot a day, (with whatever rifle I feel like shooting that day,) and would clean it after each use, the process was much like a barrel break-in procedure. Here is what it looks like today.
That is a lot better than it had been. It used to be so bad that none of my cleaning brushes would follow the rifling as I swabbed the bore; now they do.
It still copper fouls worse than any rifle I've ever seen but it shoots well.
The square outline was where a white piece of cardboard was that I used as an aiming point.
I'll continue with the cleaning process as I have been, hopefully it will be even smoother in another year or so. I probably should measure some of the fired bullets, (or slug the barrel,) to see what the dimensions are.
