My 22 shoots 1/2" groups at 50 yards/meters all day! Really? Prove it!

Nice weather today, -4 degrees with 10KM wind only.
So I took my rifle, with which I have failed several times for this challenge and done some corresponding mode to it by myself ( the rifle was drilled and tapped for scope base by a local gunsmith), to the range(indoor bench, outdoor target) , and I am very glad to get this target results.

Rifle: Schultz and Larsen single shot target rifle in 22lr;
Scope: Tasco target/varmint 6-24X42 rifle;
Ammo: Eley sport;
Distance: 50M
Groups:
1. 0.209"
2. 0.309"
3. 0.343"
4. 0.273"
5. 0.409"
Best: 0.209
Average: 0.309"

Thanks, Underthegun.
I still have an old Anchutz 22lr with only one locking screw to work on, which had been barely exceeding 0.50", and I am thinking of adding a locking screw to it by a gunsmith, to see if it will work and succeed in the challenge?
This challenge has been keeping me busy:)
 
Should we not use a standard target to shoot for this game. Here is one that is easy to print off at home http://www.keepandshare.com/doc/5198082/sent-to-myself-201 The password is DrGunner and the password is RFCtarget. I know this one is for scopes but have not yet found a suitable target for those wishing to use iron sights, still looking for one that would have 5 score targets and a few sizers. The 4 large targets and one of the small center ones would give 5 groups and the 3 remaining ones in the center could be used for sizer shots, this way everyone is on an equal playing field. I've noticed quite a few incorrect measurements being used for sizers, the bullet holes are not .224, they normally measure about .215 - .219 in my experience. Also using card stock paper for the targets will give a much cleaner and easier hole to measure. My .02 cents. :)

My scoring gauges (1 plug and 1 optical) are both 0.224

yes the scoring plus are .224 but the bullet holes in the target are smaller. Measure a few single bullet holes with some vernier calipers and you will see the holes will normally measure about .215" - .220"

Sure and the plug portion of the gauge runs around .190 as does the inner circle of the optical gauge. The scoring portion, which represents the diameter of the fired bullet is .224.
 
Do you use a scoring plug to measure groups? I don't understand why you're bringing up the scoring plug which is used to measure single holes to determine a higher or lower score for that shot such as in scoring a BR50 target. Maybe the originator (Underthegun) of this topic will weigh in here? The whole idea of my post was to have everyone shoot the same target and measure the same way. Here is probably a better explanation than I can give, copied from the site where I got permission to use their target. "The raw group size is the overall size of the group measured from outside edge to outside edge. What I have found to be the best and most consistent way to measure a raw group is to measure the outside edge of the bullet smudge on the paper from the widest point of the group using a caliper, placing the group deep within the flat part of the jaws of the caliper.
Sizers are used to calculate the final group size. What you're doing essentially is subtracting the size of one bullet with from the raw group size in order to end up with a final group size, Which reflects the center of POI for the two bullets that are farthest apart in the group. In order to calculate an average sizer, you shoot four separate sizers on a different area of the target from your groups. Measure the sizers in the same fashion as the groups – outside edge of the smudge outside edge of the smudge. Most sizers are around .210 – .215 inch, with some ammo printing larger and smaller than this average which is just an observation of mine.
Add up the four measured sizers and divide by four to get an average. Then you subtract that value from each of the raw group sizes to get a final group size for each of your groups. Just remember that the smudge represents the outer edge of the contact area of the actual bullet, and we are trying to calculate the group size from point of impact to point of impact. Subtracting a sizer results in removing 50% of the average width of a bullet from each side of the widest part of the groups, giving you the center of POI for the widest part of the group.

Because ammo and paper varies in the marks left on paper, doing it this way ensures that we are taking into account the way that your particular combination of rifle/ammo/paper is factored in by using your sizers. Because we are measuring the smudge, shooting a few fouling shots in order to dirty the bore helps a lot because subsequent bullets will print a better/more distinct mark on paper that is easier to read and see.

One good practice to help you understand why we are measuring the outside edge of the smudge is to plug a target – In particular, a sizer. Take a live unfired round and push it slowly into a sizer hole up to the base of the bullet just before it contacts the casing. You will see that the width of the hole made by the bullet is actually larger than you would expect based on the hole in the paper. The smudge left behind by the passing bullet provides a reasonably accurate estimation of the actual size of the hole, especially when averaged across four separate sizers.

In the games, you would then calculate the average of all four final groups on a target as well as an average of the best three groups on your entry.

PLEASE remember we are here to have fun and challenge ourselves."
 
Holly smokes I wasn't trying to start an argument or derail such a great thread. Whether people use a whole size of .22 as the vast majority have in this thread, .215 as you and I have, or .224 as you raised in your post, I don't think it much matters., since this is about having fun. I only rasied the fact that .224 is the standard that is used for bullet size when scoring targets, so I don't think it is nessasarily incorrect for a fun thread like this. Again, I'm not in it to argue or change what is obviously great thread, so I'll politely bow out of this one.

Great thread Underthegun, and I still think it should be stickied.

Cheers
 
I tried again today......all good till the last shot....

I did 2 trials, then a few fun shots, then back to the challenge. The last shot was the one that put me over....

Next time...

Nice shooting, that last shot in This challenge is comparible to a final putt to win the game! Gotta hold back the nerves, lol
 
Use whatever target you like. There is no reason for a standardized target. I'm fine if you subtract .224" from your outside to outside measurement.

Also, if anyone has a successful attempt at the challenge, please send me a message to let me know. I rarely check out the rimfire forum, so I might miss some successful attempts.
