Gonna start by saying that this isn't meant to diminish or discourage the shooter that printed this group in the first place. Nomatter how you cut it, it's not totally luck when you drop a group like this onto a paper half a kilomter downrange... but here's my weigh in on the group size thing...
what is the difference between 3 and 5 shot groups? In statistics three events form a trend, so do 3 shots not mean a group??
If the intent is to hit what you are shooting at, being able to make a 1.5" group at 500yds seems bloody impressive to me.
Why is it thought that 5 shot groups are more indicative of how well a rifle performs? Are you trying to determine the effect on the group from the barrel heating up, or is there something that I am missing?
not trying to be inflammatory, just trying to understand.
Cheers,

There might not be a difference between 3 shot and 5 shot groups. I'm not a statistician, so I can't say. But if this is a true "1/4" MOA gun, then five shots should hold a group just as small as three shots, correct? So just shoot five shot groups and put the argument to rest, for cripes' sakes...
The devilish side of me says that I should mention this one time I fired a single shot with a .308 at over a kilomter. The hole measured roughly .308 in diametre. That makes it .0038 MOA, right????...
I shoot 5-shot groups, I compete with what is essentially 10-shot groups. I hunt with one-shot groups. The thing is about knowing what your gun does and where it does it. I "KNOW" where my rifle hits at 100-200-300, etc. cold and clean, hot and dirty, uphill or down, rain or shine, bright sun or dull overcast. And my knowledge is based on a crapload of groups fired with my gun and a lot of notekeeping.
And I can say with absolute certainty and minimal gloating that my gun is a sub-MOA gun. I say this because in hundreds of five shot groups at 200m it has NEVER fired over a minute of angle for me when keep up my my part of the bargain. Off a bench at 100m and 200m it rarely shoots over a half minute, and I can usually count on 1/3 to 1/2 MOA after I warm it and get into my "groove." But I base my bragging on what the gun ALWAYS does - and not what it did once. It takes a bit of wind at 1000m or inattention and match conditions such as moving targetry to open this up. If I shot benchrest ( I don't) - I would care about 1/4 Minute here or there -- but the simple fact is that in the disciplines I shoot, and in the conditions most people hunt or work - a big fat Minute of angle will stay in the bullseye (or CoM) just as good as a quarter minute. Bad/inexperienced and unprepared shooters with good guns will generally be taken to the bank by good/experienced/prepared shooters on the basis of consistent performance and experience in the wind.
I think a lot of people have perfectly good MOA guns, but sell them as 1/4 MOA guns based on one three-round group they fired on a Tuesday afternoon back in May two years ago, in spite of a thousand other, bigger groups. Consider the "MOA Challenge" that one of the ORA members put up to this forum - go on down to Cedar Springs and take him up on it... Lots of guns, including every one I own can do it.... but who has actually done it, under pressure and on demand? Maybe we gotta focus on how well WE shoot, and as long as our guns are better than THAT, train, learn and improve ourselves. If you have one of those guns that can't shoot as good as you - you live your life competing or hunting in a constant state of wondering if that last miss, or that gut-shot was you making a mess of it, or if the gun let you down. (Don't even get me started on how the Army Elcan POS scope can stick it to you...)
As long as your guns shoot better than you do, you can trust the information they give you on the paper and you can learn how to do it better.. Trick poney to this statement is that the better you get, the more money you will spend on guns and ammo to keep up. That can suck. But kind of fun, too.
To be frank - most out of the box Remington 700s shooting factory "match" or decent handloads will hold a minute or better, and they will go their entire life until throat erosion finally kills them before most shooters "catch up" to them. At that point you gotta figure that if you're better than when you started, you can treat yourself to a new Shilen barrel (from Mysticplayer perhaps) and build yourself a 1/4 MOA gun on the old frame.
Also - not trying to be inflammatory, or to diminish this group fired by the original poster. It's a fine group - and I hope he can and does fire a lot more just like it. It's a good indication that the gun is one of those guns that might be "better than I am."
