Ok, so I went to an indoor range today for the first time and enjoyed it immensely. Took my trusty ol' M66 6-shot. It shot as accurately as always with 1-holers at 5 yards and 2" groups at 15. I did notice today that my gun was spitting lots of tiny specks of lead and I've never noticed it do that before. Everything is tight as always. I did use a new type of ammo - can that cause a gun to spit?
