I agree with joe b., records are not an expectation of accuracy that why they are records. 5 - 5shot groups between 1/2 and 1 inch seems about right to me. Records are generally shot in very good conditions, which is not available at any given time. Sometimes records just happen but they generally happen to good shooters.    ledball

I see no reason to quote this information. It doesn't hold up to your 5 five shot group criteria. ANYTHING could have happened if a 5th group were fired.

I beg to differ, if you can't shoot 1/2 inch five shot group averages you have no hopes ever setting a new record. In regards to the CBA National events mentioned the same holds true. If you are not capable of shooting 1/2 inch 5 shot group averages prior to your arrival you have little hope of being competitive let alone coming home with a National event title. The conditions at the 2006 National event were not the most user friendly for the 5 shot events, they never are thus the aggs. were abnormally a tad high. In regards to the ASSRA records there are always adverse conditions one has to compensate for and I have yet to be to an event with zero conditions to deal with. It is never just a trigger pull and records are never just achieved by dumb luck. If one goes through life thinking their equipment is not capable of 1/2 inch or better averages then one can never expect to achieve any exceptional goals in life. Also keep in mind what you do at 100yds to a degree equates to what to expect at 200yds. Continually elevate your expectations for your equipment as well as your own abilities, get out to the range more frequently to develop both and quit just doing the same old thing and your name will be included in the record books with the best of the best. I have never found that the naysayers finish anywhere close to the top, nor do they come up with any good advise. They try to keep those around them down to their same level as it is their only hope of ever winning. Be the opposite and push the limits to gain success and share all of those little successes along the way. Help bring everyone around you to a higher level so you are continually competing against the best and keep in mind that winning with any secret advantages is not winning at all.

John, please, let me beg to differ also, averaging 1/2 inch groups means that every shot goes into the 25 ring at 100 or 200 yds, well we know that ain't gonna happen. I have always thought our rifles are capable of 1/2 to 5/8 inch accuracy but we sometimes  forget the human element. Benchrest shooting with plain base bullets has advanced very much just in the last 10 years but we still are not capable of shooting 1/2 groups or 250's every time we set down at the bench.   ledball

Ledball I understand your argument and I appreciate all that you have to say but I just can't agree wholly with your statement. For one we can't include 200yds into the conversation, it is apples and oranges and they have no direct relationship just as score and group do not have anything in common. When the rifle is capable of shooting 5 shot group averages under a 1/2 inch, some groups will be smaller and some will be larger  but they average out to be 1/2 inch. Here is where we see some of the human error you mention coming into play as the rifle is really capable of shooting under a 1/2 inch, that is where the smaller groups are coming from to offset the larger ones that make up the average. This is also the reason why one can't make the statement all of the targets would be 250's. Groups and Score are two very distinct disciplines that have absolutely nothing in common.

And how do you know this? No matter what numbers you run, it will not tell you, you can only ass u me. If it's good with you. Why ask us to do 5 five shot groups when 4 apparently will do.?

Inquiring minds would like to know,

I agree with J Louis.

I know I have equipment that will shoot 1/2 inch average at 100 yds most times under nice conditions. I test everything before I shoot it in an event.

So being I have 1/2 inch average shooters I would not wast my time going to an event with equipment that wont shoot at least 1/2 inch  average under decent conditions. 

About the only shooting I do at 100 yds that groups over 1/2 inch is my 22 RF, and that will do 3/4 average most times if the wind is not to bad. 

I guess the difference is that some go to events to compete and others  just go to participate, and win or lose, we all have fun shooting.

I like to think I'm a competitor, not just a participant, so I bring the most accurate equipment I have to all the events I shoot in.

is MORE likely to average <.5" for 5 groups than for 4 groups. It's statistics.

But Joe you are not including the statistics of the wind. I might agree with you if the groups were shot in a wind tunnel. However it is impossible to get the same results with five groups due to the wind changes that occur over an hour (even under ideal conditions). If a shooter has not refined his wind doping skills he wiil not be able to shoot five groups more accurately than four groups. Wind change effects during the competition become greater the longer and more you shoot within one hour. Need to also include the wind statistics as well (changes in direction, intensity, gust periods etc.) And then there is ussually a change in light with time as well when clouds drift by. This can easily result in 1/2 to 1 MOA change that the shooter must dope before firing as well. The more changes that can occur over a longer period shooting will make it more difficult to shoot five groups.

I have never shot a 250 under calm conditions. I am terrible at judging the mirage. All my perfect 250 targets have been shot under wind conditions including my five groups that averaged 0.452". I believe my rifle would be capable of easily shooting 1/4 MOA in a wind free tunnel.

Statistics can be a useful tool when you're sitting in the isolated confines of the office and you're looking for indicators as you develop a hypothesis or refine a theory, but the best advise I ever received from a mentor was this:

"Get the hell out of the office and walk in the real world as often as you can. And if you keep your eyes open and are able to make valid observations, you'll quickly see that Reality takes a huge bite out of Theory's ass at every possible opportunity, and with amazing regularity."

Dave,
Your mention of changing mirage, wind and light (along with other variables) are perfect examples of Reality taking that bite.

Joe:

I have already demonstrated it can be done and now it is time for someone else to seek your award. Then we can gain additional information from this shooter as to how he managed to develop his capabilities to shoot so precisely. I believe that is how we move forward instead of always following the old school approach that only duplicates the old ways.

Harry Pope was always looking for new and innovative ways and we need to build on his experience. No need for me to win the award. I have already freely volunteered my knowledge.

I still believe five groups is a better indicator of accuracy achieved under natural shooting conditions. I was not arguing to change back to four groups. I was just affirming it is more difficult to achieve 1/2 MOA success with five groups under natural shooting conditions.

Dave
