I picked up a Remington 552 Speedmaster .22 rifle.
Not bad condition for a rife that wasn't used for over 10 years.
It was in a case that the zipper had to be broken to open.
It looks like it was never cleaned.
Barrel was hard to remove with all the fouling.
Got it apart and cleaned.
Big problem is it had a glob of rust on one side of the muzzle.
Soaked it, got most of it out using Flitz.
Took it to the range today, and shot jacketed bullets out of it.
Seemed to get better after around 50 rounds.
I still see a spot of rust.
Suggestions on best way to get the rest of it out?????
