What do you guys recommend as the best way to test for 100 yard accuracy? |

The only way to test for 100 yard accuracy is to shoot at 100 yards. There is a lot of ammo out there that will hammer at 50 but fall apart at 100. I also feel it's best to shoot from position and not from a rest. There are very different dynamics involved in position shooting and rest shooting that may have an effect on the results. My personal technique, which is far from great but it works for me in my limited time, is to get 5 or so test lots and shoot a 10 shot groups with each in random order at 100 yards without a major break in position. I then repeat several times, with a different random order each time, and the one that shoots the tightest, with no unexplained flyers, wins. While shooting I record any legimately called flyers so that my gross errors do not affect the outcome. For a target I use a black dot paster (as is used for covering shots in highpower) on the back of a 50 yard card with the scope adjusted so that shots hit a few inches high to avoid damaging my aiming point. It's all very simple and very effective.

I have doe a lot of testing at 50 metres, and a fair amount at 100 yrds. You are absolutely correct about some rounds driving tacks at 50 metres and fall apart at 100 yards.
What I have done is to test specifically for 100 yards and establish what shoots there and not worry abou 50 metres. Once I have found my 100 yard ammo, I will use it at 100 and what shoots well at 50 metres there.
Just make sure you have your sight corrections written down when you change distances. O' and always make sure you change them back when you go back to 50 yds/50 metres. LOL... Seen that kill scores a few times at matches. 
I also have found that a faster round is better at 100 than a slower round, time in the air. (Especially if there is a wind)
Once all of the accutracy stuff has been established, then I shoot in position.

LOL, looks like what I was trying to say didn't make it to the page. Oldtimers brain stuff
At a match that has a 100 yard element, I end up shooting two differant ammos. One for 50 yards/50 metres, and another for the 100 yard element.
ALWAYS write down the settings and don't get rushed and forget to make the appropriate changes in sights. It WILL be desasterous to the final score.
The term we use for those shots is "Snowbirds", all in the white.

While I agree that one should always return their sight to the zero for 50 yards when the match is over forgetting to do so, or forgetting to click up for 100 yards, should never cost a point. Just raise your hand if your first shot is outside of the sighter area and let the range officer know what happened before you take another shot (after adjusting your sights!). Problem solved!

The other element here, that sort of goes without saying, in the economy of time you should be testing combinations that you already have a pretty good idea work well at 50y/m. This does not have to be extensive testing, just "Hey does this stuff work OK at 50?" If a combo won't shoot at 50 then no use in trying it at 100.

To me something that also comes into play at 100 yards is the wind. Some bullets will handle the wind better than others. Practice, practice and practice is the rule of thumb and record everything. At 50 yards a 10 mph cross wind will move the bullet over an inch, but given the same wind at 100 yards you are looking at over 4 inches. You can only truly learn to read the wind by practicing.

There is a misconception that wind moves the projectile to the sides, ie right/left on the target.
That is true, but because of bullet rotation, it also moves the bullet up and down with that same wind from 3 and 9 o'clock. There is variation from each direction up/down as well as right/left.
Let me refer you to a great study done by Gold Metalist Lanny Bassham and Lones Wiggers. It is a DVD/CD called, WINNING IN THE WIND.
Worth the dollars to get this information. Thanks, Tim

Lanny also has DVD's on the Mental Game that are worth the investment. Great for beginners, as well as us older shooters.

Winning in the Wind is available where please? I could not find it listed on Amazon.
As far as the mental part of shooting I was coached back in the 80"s in archery. As with any sport 98% is mental preparation and control.
Thank you

For my young shooters, I always advise them to get a coat from Champions Choice. They are leather and not costly. If they outgrow them, they can then donate them to the club for other shooters, or sell them. I like the donation part because it helps the kids with less money get ionto a good coat. I don't have them get the pants or shoes at this point. They can do that when they start getting really consistant and are sure they are going to be dedicated to shooting and the team.
