Norm- You know what guys say, "it's not a real group unless it's 10 shots". I have shot both 10 and 5 shots but most of my shooting is at 50 yards. For me, the group doesn't open up that much more. At 75 and above, I can see that my groups would/could open up. But at that distance, there are a lot of factors that could come in to play, like me the shooter not reading the wind. It really is not a reflection on the rifle.
For me, I am still amazed at the accuracy of these rifles. If a guy posts a great 5 shot group, all I'm saying is give him a pat on the back, that's what he's wanting from us. Remember, if he shows his wife, she says........ that's nice, now quit messing around and help around the house. I actually worked all summer for that group and finally broke .2 in. Because it's not 10 shots, does that make it "not special". When I measured it I was hoop hollering. Showed my wife and again she said get back to work. so that's why we post on the forum for guys like us to appreciate it. I am still relatively new to pcps so My enthusiasm is still quite high. Never really shot a rifle before 2 years ago. So when Dairyboy shoots a .214 in prone with a bipod (with a Marauder), I think that's friggin great and I don't think it's right for someone to say ....well shoot 5 more and we'll talk. That what i was driving at.
