    I brought out my. 17hmr shot 5 groups. Each one wasabout an inch across at 100 yards.
    Shot at a couple of cans ans such and i went through all 50 rounds in the box.
    This is the crazy part I opened the other box and had a 5 round group to find my group was the size of a dime! This shocked me because I've always been tought that guns get more inaccuate the more you shoot them (because of the copper,lead and powder).

    Have you guys had a similar experience?

    Maybe a little practice went a long way.

    Just a thought.

    Yep. All the time. A gun that's freshely cleaned w oil in the barrel is less accurate because the oil downstairs allow good grip between the lands and the bullet. That's why your supposed to run a few dry patches down the barrel before firing. Same concept w a fouling shot.

    Good to know.
    I will keep that in mind when shooting "long range" with my .17 (>300 yards :p)

    Probably combination of fouling the bore and practice. Also by chance could it be the second batch of ammo is more accurate. If they have different lot #s there is more of a chance of difference.

    It's true. I work with a guy that does bullseye shooting and he swears by it. He clames to have a 30-30 that holds tighter groups after 3 shots.

    I usually associate dirty with looser, but that's another thread..

    There are so many factors that it ain't even funny, up to & including the barrel heating up and moving ever so slightly...

    Look up "Cold Bore Zero" and go from there...

    I think a lot of it has to do with a clean bore having more friction than after its had a couple rounds run through it & also once you've shot a couple rounds thru a clean bore the fouling allows for a tighter seal to the rifling & all the expanding pressure staying behind the bullet & pushing it allowing for greater accuracy? Seems to make sense but I could be totally wrong??? All I know is my 10/22 will have a couple flyers in each group for the first 10 or 12 shots if I have thoroughly cleaned & scrubbed the bore, which I don't do very often. Usually I just run a patch thru 1 quick time with hoppes or rem bore bright & pull a bore snake thru about 5 or 6 times & it will stay pretty consistent from the first shot on. Most of the diff is me I think. If I'm not going shoot for a while I'll run an oil patch thru it but clean it out before shooting it next time.

    I know several experienced shooters who don't clean their .22's until it starts to misfire. I don't clean my .22 after every trip to the range but I do clean it before it begins to misfire. I can't stand a dirty gun and I'm afraid it's going to ruin the finish if I leave it dirty. I just think .22's do better when after some use.
