Carl(aka rifle50) used a 39" plate at 1065yds. I'm thinking if it was 40" than divide that by 10 for 100yds.4"@1008"@20012"@30016"@40020"@500 24"@60028"@70032"@80036"@90040"@1000
IMO, without a maximum target size there is little point.... I suggested earlier 6 MOA, which is pretty generous, it is typically the size of the black bull (aiming portion) on most NRA targets.... That is (roughly) 6" at 100 yards, 12" at 200 and 18" at 300, etc.... Whether you use that for a group size, or just something that you hit "most of the time" should be discussed.... JMO....If you want simple, but harder the further out you go.... how about just use a piece of 8.5 x 11 paper.... Hitting that at all at 300 yards would be pretty darn good, IMO.... *LOL*....Bob
I think it should be kept simple, this is for fun after all. I don't think caliber matters, shoot what you got. I do think there should be some type of standard that has a bit of a challenge but keep it simple.Lets see what Monkeydad says, he started this whole thing .
I really think having different targets for different calibers or actions is unnecessary.... I made a challenge a while back to get guys to shoot five consecutive 5-shot groups (on one piece of paper no other holes in the target) at 50 yards that you could cover with a dime.... That works out to about 1 MOA C-T-C, BTW.... One of the TWO guys that did it used a springer !!!If you give an advantage to .177, then a powerful PCP with very heavy pellets will have an advantage over your usual .22 cal and probably even most .25's.... The BIGGEST difference is between pellets and bullets, the latter can drift half or a third as much as a pellet.... Why not, at least for now, just use 4 MOA at whatever range you want.... Have the shooter specify the caliber, gun, and pellet, along with a guess of the wind conditions.... Let your own personal satisfaction be your reward if you do it with a .177 instead of a .25 cal.... or with a pellet instead of a bullet.... As things progress, you can always add an "Expert" category that is 2 MOA.... The question about what is required, a single shot, 3 out of 5, or a group, is another question.... I personally think a single shot (with no limit on number of tries) means nothing.... I could hit a pop-can at 200 yards, given a tin of pellets.... The other option is to shoot for score on a standardized target, with different catagories (Expert, Marksman, etc.) at each range.... How complicated do you want to get?....Bob
I think 5 shots out of 5 at under 3 MOA is too tough once you get much past 100 yards.... Even at 100 yards, it's not easy.... JMO.... For a good pellet at a decent velocity for the job (eg. 18 gr. JSB @ 950 fps) you get almost 1" of drift per mph of crosswind at 100 yards (8.55" in 10 mph).... You can't even feel a breeze less than 3 mph on your skin, and it won't move leaves.... For reference, Google "Beaufort Scale 1 Wind".... There is your 3 MOA right there, and you would never even know why a shot or two is out of the group....At 200 yards, it's nearly 3 feet of drift in a 10 mph wind.... There is a big difference between hitting a 4 MOA target "most of the time" and getting a 5 shot 4 MOA group.... Carl was only getting a few hits out of many shots at 1065 yards on his 39" plate (~ 4 MOA).... I have no idea how hard you want this to be.... but let me propose 3 hits minimum out of 5 shots inside a 4 MOA circle (typical size of a 9 ring on a target) to qualify for a given range, as a starting point.... If it's too easy, you can always change it, or add a more difficult task for a higher level rating.... No allowance for caliber, type of airgun, wind, or ammunitions type.... but those are to be stated.... JMO as a starting point.... Another possibility.... 1 Milliradian is 1/1000th of the distance to the target.... We call them MilDots.... 3.6" at 100 yards (3600 in.), 7.2" at 200, etc.etc.... If you can hit a target that size, you could call it a "one in a thousand" shot/target.... *LOL*.... Forget about MOA, and just use Mils?.... For the categories, using MilDots, and 5 shot groups, you could use....Marksman - 3 shots under 4 MOA or all 5 shots under 8 MOASharpshooter - 3 shots under 3 MOA or all 5 shots under 6 MOAExpert - 3 shots under 2 MOA or all 5 shots under 4 MOAMaster - 3 shots under 1 MOA or all 5 shots under 2 MOAAgain, just some suggestions.... Groups by themselves are more a measure of the gun, IMO, because you might be 3 feet off the target if your paper is big enough and still pull a 2 MOA group.... Is the object to shoot a small group, or hit a given size target.... actually a BIG difference in those goals.... Hunting, after all, is hitting a target....Bob
