July E-Postal - Math

This months e-postal features a Venn diagram, famous for sorting characteristics and giving names to the combined subgroups. Here's an example:
O.K. maybe I should have found one with pistol, rifle, and shotgun shooters instead of  this one, but hey, it was there. Lucky you, it's not the target.
This is what the target looks like:


Don't use this one. Go here and print it out to get full size. NOTE: This target is displayed in landscape, NOT portrait. Be sure you tell your printer this before you hit Print.

This should be easy since the numbers serve dual purpose. The number in each zone is both the number of rounds you will shoot in that zone, and the points per hit for each round. So 3 shots in the '3' zone, 2 shots in each of the three '2' zones, and one shot in each of the three '1' zones, for a total of 12 holes in the paper.

Scoring: 3 points for each hit in the '3' zone, up to 3, 2 points for each hit in a '2' zone, limit 2 hits per zone, and 1 point for each hit in a '1' zone, limit one hit per zone. Hits on a line are counted in the shooters favor.  If, for example, you put 4 rounds into the '3' zone, only 3 of them will count for 3 points, but if one of them is touching  a line, you may count it as a '2' or even a '1' if it's on a corner.

Put your name, class, gun and caliber, score, and anything else that might be of interest in dark ink up by the label "Billlls Venn Diagram.", and e-mail your results to bllew at rmi dot net.

Max score is 24.

Shoot this standing, unsupported at 25feet/10 yards.

There are five different classes
1.  Rimfire firearms with iron sights
2.  Rimfire firearms with optics
3.  Centerfire calibers with Iron sights
4.  Centerfire calibers with optics
5.  Math Is Hard class

Class 5 is open. Airguns, blowguns, whatever. Just let me know what you used and from how far away. Optics implies magnification so red dots shoot with the irons.

Note that it is possible to get a perfect score by putting all 12 shots in the '3' zone as long as they strategically touch the boundaries in the right places. Doing this with a large caliber gun would probably make the target unscoreable but fun to look at.  Good luck.

So, can I use multi projectile loads to get all my shots at one time:)

I thought about that. What size shot results in 10 balls in 1 12 ga shell?

At 25 feet, the wad would make a pretty good sized hole itself. Better drop that to 9 or else back up to 25 yards or so.

Definitely class 5.

Include video.

I'll make up some 12 ga handloads with 8 00 and 2 #1 pellets and no shotcup.

I'll also use a discarding sabot to avoid destroying the target!

How about that?

Let's see, with a discarding sabot and no shot cup, you'll need 8x00, 2x#1, and 2x 1/4-20 hex nuts to make 12 holes in the paper.

Wasn't there a cowboy movie involving Billy the Kid in which a black powder gun was loaded with 12 dimes? As it happens, I have a 16" blunderbuss barrel in that caliber. Needs furniture. Better get cracking.

Be sure to mention how far back you had to move to get 12 distinguishable holes.
