The QB58 is a beautiful side-lever rifle in .22 that shoots right at 600 with Beeman Round pellets (will include 2 tins of them). This rifle is as new and HAS been taken down, cleaned and lubed. The cocking action and shot cycle is smooth and the accuracy is outstanding. This rifle has right around 750 pellets through it and was my go to plinker when I was outside grilling. At 25m I am shooting sub-quarter sized groups rested; she is not hold sensitive at all. Yes, this is a Chinese rifle but it is seriously impressive and built very nicely. I can shoot this rifle all day without fatigue due to its carbine size and ease of cocking. This rifle will not disappoint!
If you have a known good scope, I'd try swapping scopes first. It might take a couple of shots to loosen it up after sitting for awhile.
Good point Bill, I will try and "Chrono-connect" it tonight.
So tomorrow I will crunch the numbers in an excel spread sheet.But in 25 shots the FPS at 30' lowest was 444, highest was 452... guessing the average was 447 judging from the majority of the shots.That is a 8 fps spread at its EXTREME.
