If you have a chronograph you can see a rather significant difference in velocity from a clean barrel.
Heard a lil tidbit the other day and was wondering if it was true or just some fudd myth:
-Don't clean your gun after zeroing it before hunting because a clean gun will be off zero till you get a few shots down the barrel.
If you start out with a clean barrel, after sighting it in without shooting, then take 3-5 rounds to get it in tight, not cleaning will drop the bullet, cleaning will raise the bullet. Just bring the sights up a couple clicks to compensate. If you own the rifle, and are going hunting with it, you should be comfortable enough with the gun to know the discrepancy between clean and shot barrels.
If you know a clean barrel jumps up 1/2 of an inch at 100 yards, then you know it will jump up 1.25 at 250.
It's just that cleaning is imperative for those who hunt with milsurp rifles, and quite a few do, even with newpro ammo rust is an issue.
.....reason being is that only about 1/2 of them cleaned the rifle since last year's deer season. The other 1/2 cleaned their rifle sometime after deer season and haven't shot it until now, 1 week before opening day. The best that you can hope for is to get their rifle sighted in and get them a bit more familiar with their rifle before they take to the woods.
Are these the guys who expect 1/2 MOA performance and shoot at everything from 25 to 1000 yards, but don't practice?!
What a sad comment about the level of marksmanship and the average deer hunter.
(they even use target backers for each shot to confirm that a shot was indeed fired)
