My grandson got a Benjamin Summit .177 air rifle this past spring and him and his dad were shooting it in the basement and was getting horrible groups. I looked it over today and found the scope rings were not tight to the picatinny rail mount. I was thinking of pulling the scope anyway and when I did I heard a rattle in it. I'm think the loose rings beat the heck out of the scope. So we mounted the Gamo that came with mine since I opted for a Hammers 3-9x40AO as soon as I got mine.

We were shooting the regular Crossman 10.5 grain .177 pellets and they were all over the place at 10 yards in the basement. I know I had to really move the turrets but after tapping on them, I'd get 2 shots fairly close and then a flyer 6" away. I was shooting with 2 bags off the bar counter and I know I was getting great trigger pulls - although that 2 stage trigger sucks imo.

I saw some of the pellets were a bit deformed at the rear so I didn't use them. I have a Gamo Tac and I think I can keep everything inside a nickel at 10 yards! There probably at least 150 shots thru it and 50 of them are mine from today. Just wonder if anyone has an idea on these flyers and if this is enough shots to "break it in"? His dad is going to contact Benjamin about it. Thanks.
 
So my advice is try 7.5 grain as well as 10.5 but 10.5 can be heavy in some guns. Im not familiar with your grandsons rifle but I would get crossman premiers, jsb, h&n, and possibly some Benjamin brand pellets although the first one id try is jsbs. Premiers are cheap and cycle through all my guns if i match the grains up to the gun i use. If you find that its totally inaccurate no matter how many pellets you try you can then make a decision on how to troubleshoot from there. Good luck mate

A couple of facts to consider imho. You must have a scope designed for springer/nitro piston airguns and a matching mounting system. It is essential that the scope has objective focus as well as ocular focus if you want fine accuracy at shorter distance and then the longer distances as time moves on. You must learn the "artillery/springer hold" through study and practice as that style of rifle prefers it. I've read and experienced that it takes 500-1000 pellets to settle the action in for best accuracy although your mileage may very. Virtually every rifle has it's preferred pellet also which once found will give you the greatest satisfaction. I hope you find yours very quickly. VERY LITTLE NON DIESELING OIL is a great maintenance study also. I wish you years of great fun and enjoyment! Bill

Try giving it a cleaning. Benjamins are filthy from the factory. My Wildfire was shooting all over the place when i first got it. I tried 7 different pellets types and brands and 2 would hit bullseye then 4 would fly off and hit the target next to mine then one smack dead center. So frustrating. I cleaned it up with a homemade stringtrimmer patch puller and some wd40 and this thing looked like I had been shooting black ink thru it. Took me a dozen or so wet patches to get clean. After runnimg 4 dry patches there was not a speck on the last one. Suddenly that gun tightened right up. All my pellets are grouping at an inch or less(still not great but but for this cheap plinker and pest control gun I can live with it). 250 shots later she still shoots the same.
