Brag about the best group you ever shot!

Sometimes we get lucky and pull off a great group luck or skill it happens time to time.

Not saying you can do it every time or even the gun can but whats the best you have ever dne at 100m and a 5 shot group.

It hapened to me yesterday, pretty good group and my personal best at 100 m and 5 shots with a 6mm. If i ever duplicate this again it will be luck!

So please go ahead and throw out your numbers.
 
The other day I just put on a new barrel on my 6br. The first group through the rifle 5 shots of old barrel ammo went .289. I was surprised at that. Years ago I was fire forming 220 Russian into 6ppc and shot a .029 group. The gun never shot a group that small again for me. If it a really good group save it they are alway a great conversation piece with the shooting buddy's
 
The is the group that everyone calls bullshyte on when they see it, but it IS 5 shots from 110 meters using a 6BR, 30.4 grains of Varget, Berger 105 VLD's with Lapua Brass and CCI 450 primers. Nesika J action and Krieger barrel.

SKS with milsurp czech ammo, 3 (out of 10) touching at 100 yds with iron sights, with the rest all over the map .... I'm still scratching my head at that one, two touching is pretty common (and plain luck) but 3, I must have been doing something VERY right that day ... Just never managed to figure out exactly what it was ...
 
I shot one yesterday will never match it again, at .064 at the range when i got hoe i remeassured it at .089 moa wit proper measuring equipment. First and prob last sub .1 moa...

I shot mine with a 6mm BR 30.0 gr of varget a 107 SMKs soft on the lands just kissing it, CCI BR primers and Lapua brass out of the box not fire formed.

Had many good groups until the rain and wind showed up, than it went to rat poop lol!

LOL and the funny thing the gun! Savage F-Class factory.

Just answering the title question... What is the smallest size for a 5 shot group?

It was shot in registered competition many years ago with a moving backer, and it will probably not be broken...

I think I have the facts correct here...
.009" center to center... it had to be measured with a device measuring the amount of light passing through a hole... at the range is was official measured as a "zero" group... it was a .222 Remington shot by Pat McMillan.

It demonstrates there is some luck involved when only one group is taken into account... and why aggregates are much more important in measuring accuracy.

That group with that equipment is totally believable.
 
.300 WinMag @ 300 yds

pictured is the 10 shot group at 300 yds, and the rifle that made it. for comparison i have included a loonie and one of the Black Hills 190gr match rounds. the squares on the paper are 1". the group measures a hair under 3/4".

My groups don't get any smaller on the internet! The distance usually doubles or triples, but the groups stay the same ;)

Not me I blame the weather on 99% of my shots, and when I get a good one I say the wether was perfect LOL! That way its never my fault ;)

I also get my best groups when i fire one shot!

I don't know what the thinking is here, but you cannot just discount 7 shots of a 10 shot group. What you did right that day was get lucky twice.

To explain, lets look at a grid of 100 squares, and bullets hit only squarely in the centre of the squares. Chances of hitting one square with one shot are 100/100. Chances of the next shot hitting an adjacent (by edges or corners) square, or the same square, are 9/100. Roughly 1 in 10, which would make it pretty common, hence your statement "two touching is pretty common (and plain luck)". This is getting lucky #1.

Now if you take a third shot, there are 13 "adjacent" squares if the first two were touching by corners, or 11 if the first two were touching by edges, or 9 if the first two were the same square. So we'll average it at 11. Thus the chances of hitting the third shot touching the two shot group are 11/100, or roughly 1 in 10 again. That's getting lucky #2. So to add it all up, the odds of getting three shots touching is 1/10 multiplied by 1/10, which gives you a 1/100 chance of getting 3 shots touching out of three shots. If you take 10 shots.... well let's just say the odds of 3 touching go up dramatically.

I really don't see how you can think 2 touching is luck, but 3 of 10 is suddenly a burst of skill. It's just a bunch of randomness and probability. Like I said, you got lucky twice. But as long as we have fun, what does it matter anyway?
 
A single five shot group fired with no witnesses means just slightly more than nothing. If the subsequent group is ten times larger, it means even less. If, during the life of the rifle, the group is never duplicated, it has been demonstrated to be a fluke. I have fired a sub 1/2 inch group from a Lee Enfield. I have done the same from a 308 Norma hunting rifle. In neither case was I ever able to duplicate the feat. They were flukes.
My best group fired in registered competition was a .089. This was fired from a rifle which regularily shot around the .200 mark. It was a fluke. My best ever group fired in practice was a .021 from a 223 with which I never won a damn thing! Another fluke. Enjoy your occasional fluke groups but don't give them too much weight. Regards, Bill.
 
more and more i am beginning to think that it just isn't worth it, to post anything, anywhere on Gunnutz. a person will start a thread about a particular interest/subject/question or what-have-you, and without fail in less than ten responses the topic has been taken a completely absurd direction by people who want to argue, insult, nit-pick, and otherwise degrade the issue because they have no lives, and, in those lives lack validation. they come on these forums so that they can piss down the backs of other members, ANONYMOUSLY! how very brave of them. if a guy says that he shot a particular group with a particular rifle, THEN HE DID! he's provided a picture of the target, which is more proof that he did it than you have proof that he didn't. if people want to tell lies then that is their business, and at the end of the day they have to live with that. this may come as a big surprise to you people but we are supposed to as a community support each other and collectively improve our lot. i am sincerely sorry for this rant, but i WANT to continue to enjoy these forums AND be a constructive part of them, so for God's sake, stop your pissin' and moanin' and if you don't have something useful/respectful to say then KEEP YOUR F#$%ING mouth shut.
 
I hate to break up the love-in but.....I can relate some cast bullet groups from the CBA, these are groups fired in Competition, I'm sure many of these folks have shot smaller grps. though not in a competition.....100yds. .154", 100yds. plain base bullet(breech seated) .1903"......top score: 200-17X....i think these results are gratifying to all that use cast bullets as it truly reflects accuracy on the part of the reloader, who is the only one who actually makes his own ammo including making the bullet!!
 
I don't know if I should post this 'cause it was the group I got with the last 4 rounds of my batch of handloads. Ahh what the hell! Four (not the requested 5) shots at 100 metres, 165 gr. Sierra BTSP, on top of 48gr. of H380. A dime covers it nicely.

I can count five in there... one in each corner and one right in the middle... ;)

Ivan... do not hold back - tell us how you really feel. :D
