There is no such thing as every time all the time, my friend. Guns burp even hight dollar guns burp. There are wind gust, a spider could crawl into your scope, you could get a crappy round. You could sneze, you could hick-up. Anything could happen.
There are indeed "all the time" guns. In a benchrest match, if you drop a 6 on just one bullseye out of 25, you're done. You might as well pack up your equipment and head home because you're not going to win. It's the same in nearly any high level target shooting match. Do you really think that the top level competitors buy the expensive guns just for looks?
All that stuff that you say "could happen" can't in a match. There are reasons that people use wind flags, why they use scopes that don't have openings for spiders to crawl into (can't say I've ever seen a scope that does have those, actually), and you use high quality ammunition. There's also no sneezing or hiccupping during the trigger squeeze sequence if you're even a halfway decent shooter, of course.
But, what I do not understand is why do people like you have to push bottons and test people like me or Jim? Why can you not just let it be. Why say things like we should be in record books? I take it you could not do it, thats why I sould not be able to right? Well do me a favor, dont take your inability to shoot out on me or other people on the forums. Maybe you should just do a little less talking and a lot more shooting.
I was trying to keep this as friendly as possible while trying to ask that you only post information that's actually true and make sure we're all using group measurement the same way. Since it looks like you would rather slam my shooting skill, so be it. You flat out are not shooting groups where one hole touches all other holes at 50yds. That's less than .25" groups center-to-center and no Marlin 60 ever made has been able to shoot groups like that. Period. The fact that you claim to be doing it off anything other than benchrest equipment without using competition wind flags makes your claim even more ludicrous. Also, claiming that your gun shoots groups that size because it has done it a few times is blatantly false. It's not my "inability to shoot" that's making me doubt your claims. It's the fact that I've seen some of the best rimfire benchrest shooters in the nation shoot and on their best days they are shooting at or barely better than the level that you claim to be with a gun that even the manufacturer will tell you has no chance of shooting like you claim. If you are saying that you and your little Marlin are so great that you are equal to the best benchrest shooters in the nation, who must also have an "inability to shoot" since they only shoot into the low .20s with all their expensive equipment, then show up and a benchrest match and win some prizes. Until then, just tell the truth.
This isn't an ego contest. It's a place where people should be able to come and share their experiences and ask questions without having to sort through bravado and falsehoods. New shooters aren't going to be able to tell so easily who is stretching the truth or worse, and are going to think they can just go grab a Marlin 60 and a brick of bulk pack ammo at Wal-Mart and shoot quarter inch groups at 50yds. When it doesn't happen, they're going to get disappointed and confused, as well as discouraged. The absolute last thing that we should be doing is causing new shooters to get discouraged.
The Marlin 60 is a good design for an inexpensive autoloader and will shoot circles around a factory stock 10/22. It's a very good gun for the price and is fine for casual shooting or hunting, just as it was designed to be. That's as far as it goes, though. Claiming it is more when it's really not just taints how good it really is for its intended uses.
Just to be clear on another issue being discussed, if your gun has shot a few good groups and the rest not so good, it does not mean that the gun shoots great and the shooter sucks. It's just probabilities at work. Even a gun that averages 4" groups at 50yds would shoot a half inch group eventually if you shot enough of them. I really wish that were not the case, but it is.
