    I have an R7 that shot horrible vertically stringing groups like your gun.

    I purchased it "as is" for low cost from an experienced airgunner that had given up on it.

    I ended up swapping barrels with another gun which solved my accuracy problem; what I'm saying that both guns
    would shoot accurately after the barrel swap. My barrel detent mechanism worked properly with one barrel/compression tube combination but not the other. This is not common, but definitely happens.

    Your gun may be defective.

    I'm pretty sure there is a defect of some kind. The guy I bought it from won't even consider the possibility that something is wrong with the gun. It shoots good with iron sights so I've got that going for me anyway.

    Try installing an aperture sight mounted on the receiver. If accuracy is off then there is something wrong with the barrel lockup. If accuracy is good then it’s your mount/rings.

    R7s are not known for being especially hold sensitive. There's not much recoil and they tend to be pretty well-behaved. They're easy to shoot well.
    If the problem is the barrel detent, you're probably getting some significant velocity variations. High when it closes tight, lower when it's not closed tightly and air escapes at the breech. I guess if the accuracy is making you happy it's not a big deal, but it's still not right.

    I'm not happy about it at all. I can't shoot iron sights very well because of my old eyes and as the gun is I can't use a scope. My problem is that Mike Melick won't even consider the possibility that something is wrong with the gun and he won't do anything about it. I paid him $350.00 for the gun and his last message to me was and I quote, " please read the warranty on the website, minimum of $50 to test rifle"

    If I pay him $50 dollars to test the defective rifle along with shipping, I'm soon going to have more money in it than it's worth. Not to mention the scope and mounts I bought and now can't use. I'll just make the best of it and get what use out of it I can.

    Again, I want to thank everybody who responded to my question for their advice, at least I now believe there is an actual problem with the gun.

    I had a similar experience. Never again will I buy from that seller. Only buy an airgun from a seller that has a no questions asked 30 day return policy.

    Yep. At the end of the day he sold me a gun with a defect and wouldn't do anything about it. Not exactly the world class service we hear so much about.

    If you ever do get it figured out, I'd be interested to hear your findings. Take care, good luck with it.

    well tightening the pivot screws should not be what holds the barrel up= that proves there is something wrong with the detent and the gun is indeed defective... the seller should not be charging you anything to look at a gun in that condition and should fix/replace or give you ALL your money back shipping included!

    That was after the gun was cocked. It locks up ok but if I close it very hard it will often bounce back open . A guy on another forum told me the breech seals on the HW30/R7 are often oversized and that keeps the gun from locking up correctly. If that is the case he says after awhile it will flatten out to the proper size and start shooting like it should. I'm hopeful he's right about that. If that is true, I'm surprised that a world class tuner wouldn't know about it but apparently he didn't .

    I'm not here to bash anybody. The seller has a great reputation in the air gun community. I don't know why he took the approach he did but as the great John Wooden said “Be more concerned with your character than your reputation, because your character is what you really are, while your reputation is merely what others think you are…the true test of a man's character is what he does when he thinks no one is watching."

    I am not sure I would call a guy who specializes in tuning chinese airguns as a "world class" tuner :p

    Could your scope be touching the rear sight when closed? If the scope is good and the gun shoots good with Irons, it has to be the mount somehow. I had a drooper mount slide back when I 1st mounted it on an R7, I didnt think it needed the pin, but it did. Also, I had my R7 start to scatter shots and I found the stock screws loosened. I check then weekly now. The R7 is a great rifle. You just have to find the culprit.

    I've tried several mounts both one and two piece, no difference. A number of people have told me the problem is the barrel not locking up in the same place every time. Since the rear sight is mounted on the barrel it still shoots straight with the iron sights. I'm told the breech seal could be oversized and if so it will flatten out as time goes on. There may be some truth to this as the last time I tried a scope the gun shot a little better. Group size was still about 9 inches in a vertical string but as least it was something that could be called a group.
