I wasn't sand bagged, just using the Harris bipod and sitting at a bench. I was using Art's method of timing the trigger squeeze to when the crosshairs met the target. Worked pretty well.

BTW the rifle was a Browning A-Bolt Varminter .308 with 165 grain HPBT Sierra's over IMR 4895. I don't remember the amount of powder, but the BOSS was set on 4.4

Anyhow, thought I would brag a little because I rarely shoot groups this well.
 
Congratulations. Remember though that your worse group and not your average is what you should consider prior to taking any critical shot.
 
Kilgore, you picked the right place to come and brag. It's always exciting to shoot a 1/4" group, but when you don't have a shooter friend to show it to it's not as fun. The non-gun owners I know aren't jumping up and down when I show them a five-shot 1/4" 100 yd. group. They don't know that for most shooters that only happens once in a blue moon. So brag away. I just did. ;)

It was at 100 yards and it was a three shot group. I had a friend there with me so he saw it. I wasn't going to mess the group up trying for a 5 shot. I will next time now that I have this one under my belt. The next 3 shot group was about an inch... which is ok I guess. I just had to brag...

I cut out the group and it is going into my safe deposit box. :P Silly I know.
 
KilgorII, Don't put that target in your safe deposit box, put it in your wallet and show it off! Reminds me of the time I... No, that would be braggin on top of yours. The thing finally began to fall apart in my wallet but I had fun. Even some non shooters were impressed.
Have fun.
 
Hey, I'm interested to hear about some shots you guys have done. Brag away as far as I am concerned.
 
Whups, I just thought that target rotted away in my wallet! That was a photo copy.
Here is a url to the original http://www.acmecity.com/rosie/flower/304/2506grp3.jpg This one was way too cool. New rifle and barrel, fired 2 fouling, sighting shots, dry patched bore and fired those five for effect. New load, new caliber for me. Too bad it never happens like this very often. I'm not so great with the graphics and tried to get the lines on the target to their correct 1/4 inch but.....
Haven't done it before or since with a NEW rig.
BTW I was bagged but not tagged!
 
Since we seem to be informal, ie the post concerns a 3 shot group, I once took a 375 yard shot at a honeydew melon with a face painted on it, aimed right at the nose, expecting a hollywood blow up.

Nothing.

I came totally off the weapon, loked at it through binos, nothing, so I re-set and took another shot, really concentrated on hitting fruity right in the nose, still nothing.

At about this time, I've got steam coming out of my ears because this fancy rig can't seem to hit squat, so I traipse up the 35 degree slope to punch the melon with my fist, it's about 110 degrees out, I'm dusty, tired, etc.

Well, I get up there and see two holes in the "upper lip", about 1" apart, at almost exactly the same level. It seems the duct tape holding the melon to the mettallic silhouette held it together.

I just wish I'd taken a third shot.
 
Hey CG87, good to see you over here at TFL! Were those shots with that rifle we were discussing scope options for by email?

I just shot a 5 shot .205" @ 100yd with some REALLY old Federal Gold Medal 168gr .308 I picked up this weekend, I gotta chrono some of this stuff and compare it to my new GM stash just for giggles.

The last five-shot group that I measured was .246". That's with a Rem. VS, .223. Pulled five rounds of Ballistic Tips that I'd loaded up several months before, and the first five down the tube went into that one hole. I've shot a few others in that range, but just don't do much measuring. I never count a group of fewer than five shots.

You guys are definately out of my league if you are doing groups like that consistantly!
 
1/2" + or - center to center for 5 shots @ 100yd are the norm for me with my .308 PSS with the odd itty bitty group like the one described above to brag about now and then! ;)

Just get someone who knows his stuff to make sure you are doing everything properly, and practice, practice, practice!!! I've probably put 1 or 2 of the Federal executive's kids through college buying Gold Medal Match .308 ammo. I'd take up reloading, but it'd cut into my trigger time!

I was shooting for group with my PSS at Camp Butner a couple weeks ago, rounds 26-30 ended up in a 3/8 inch group (5 rds). Could not believe it nor have I done it again. In the police olympics last saturday, my last group at 150 was about 3/4 inch, one hole for 5 rounds.
The oddest I shot was a 3 shot group out of my Savage Scout. It measures out to be about 5/16 inch. I had just taken the rifle out of the stock to reset the trigger heavier, set it to light and it slam fired. Trying to put it back to zero, fired one, fried another, same hole abouts, did the third and wah lah, there it was. Taped it in my rifle box.
Usually when groups like this occur, the planets are in line, the sun is right, and the shooter is in tune.
 
I shot a little benchrest in my earlier days until it became boring but the loading techniques I picked up stayed with me. Loading to benchrest standards can be time consuming but it is worth it.

My favorite day on the range was with a Sako .270 that I had spent a little money on and some time with. It looked like a regular hunting rifle but the action was square and bedded along with a couple of other tweaks.

When I arrived at the range, a group was there sighting in their rifles in preparation for hunting season. I set up my target and fired five rounds. My group was 0.65 inches which ain't bad for a .270 Winchester and did draw the attention of the crowd. One shooter insisted that it was a lucky group and I couldn't do it again.

Challenge accepted. With the crowd now watching instead of shooting, I settled in, got into benchrest mode and fired five times. The resulting group was 0.3" I let one of the other shooters try the rifle with my ammo and he put his first three into less than half an inch and five into .75 inches. He offered to buy the rifle on the spot and named a very attractive price.

I declined his offer, packed up and went home knowing that I'd never match that .3 no matter how often I shot that rifle.
 
Well, next week I'm shooting light, heavy, and sporter in the NBRSA Benchrest Nationals. I don't have a chance of winning, but hey... I'm going to need at least two, maybe three, groups with each class that are under 0.2 MOA, since I know I'll likely have a few groups expand on me... My 0.070" short .22PPC/Waldog is capable of shooting sub-two, and my Lilja 6PPC barrel was looking good last weekend, with several 200 yard groups under 0.60" including my flyers...
 
Guys,

What is the proper method for measuring groups, especially when they get so small? When the bullet diameter is greater than the size of the group (.25" group with .308" bullets), how do you measure?
 
TaxPhd-

Measure the group outside to outside at it's widest point and subtract the bullet diameter.

Example:

5 shot group with my .308 measures 1/2" wide, or .500". Subtract .308" for the diameter of the bullets and you get .192", this is the size of your group center to center.

To get really scientific at it, what you do is order a caliper add-on from sinclair's... It gives you a pair of little circles, each the size of the bullet you're using. Center circle 1 on hole #1, and circle 2 on the most distant hole, and you've got your measurement. Since you're using holes the size of your bullets, you don't have to worry about math...
