I have almost 500 rounds of JSB EXACTS .20 13.73 grain shot through My HW100 about the last 100 rounds are so the accuracy has went down hill! Went from almost pellet in pellet to about a nickel in size with a few flyers at 25 yards? Thought it might be the stock screws being loose tightened them up and it made it worse? Any ideas what the problem is? The pellets are from the same tin.

Accuracy issue.

I can not say for sure, but I had an air rifle where the accuracy would drop off on it after about 400 pellets down the barrel. A few cleaning patches and the accuracy would tighten back up again.

Also what way do you recommend to clean it? Beeman felt cleaning pellets if so do you put anything on them?

Pulling some patches through will do a better job.I use wd40 on some patches then pull a few dry patches. Here's a video from Michael on how I do it also

I have found that cleaning pellets don't seem to work very good for me. I just use dry patches as it seem like there is not much need for solvents to get the barrel clean. I do know that some people use different kinds of oils, but I can not say what. I am always a little cautious about using oils where the can come in contact with the O-rings as some will cause them to break down leading to leaks.

If tightening the stock screws made grouping worse, the problem could be misalignment of the barrel band resulting in sideways pressure on the barrel.
For this very reason I use mine without the barrel band.

Thanks for the advice everyone, a person suggested I check the screw that holds the barrel on. I did and put about a 1/4 turn in it and My gun is back to it's accurate self.

It's always the little things that will get you when it comes to a drastic change in POI. Always a good idea to check the tightness and barrel band location on a routine basis as well as scope base mounts. I have been frustrated may times with these little demons and gremlins as well.

As to cleaning the bore, I have one rifle that does not drop in accuracy until after a couple thousand shots + - , one about 400 & another @ less than 100. It never ceases to amaze me. Another thing is none of my rifles like lubricated pellets , except my last purchase. That is the Daystate, my groups shrank immediately after lubing pellets & barrel stays cleaner longer. These air rifles are an adventure and what one does or likes does not apply to the next. Just when you think you have it figured out, you don't.
