I picked this interwar era sporter made on an early Gewehr 98 receiver last Spring in a Rock Island auction. Sent it off to NECG for claw mount rings and a scope friendly safety. Very, very pleased with how it turned out.
Since it decided to be Winter all April, haven’t had a chance to do any load development today. Loaded up some Hornady 170 grs RN and IMR 4064 starting with a very modest 47.2 grs. Couldn’t understand why I was getting heavy heavy bolt lifts. Stopped after five of those.
I did a chamber cast when I got this and slugged the barrel. It miked as a tight .323” But I thought I should give it another clean and confirm. I thought I had given it a proper clean before sending it off to NECG.
Apparently not.
I have never, ever seen a rifle barrel this filthy. I don’t know if it’s ever been cleaned. I struggled to get an 8mm brush down the bore. Been at it for 1.5hrs. Removing layers with copper fouling in between. The patch in the foreground is the most recent!
I think I’ve found the source of the abnormal high pressure...
