This young man took a small doe at 482 yards, one shot.
way before he was borne I've been using tape at the end of the barrel, in this case
you can see it has a muzzle brake on it.
Now, you can see the tape and also a white tissue. The reason is that once, long
ago, the tape messed the barrel's finish (some discoloration), so I always use a lens cleaning tissue under the tape to protect (if it needs protection) my barrels.
It happened on a none stainless steel barrel but I just do not discriminate!
The tape gives me a piece of mind, not so much worried about the rain as the flying
particles in dry areas like sage brush that is abundant in Nevada and when you drop
on the ground to shoot etc. I just want to keep garbage off my barrel!!!
