200 yard groups

[jaybray]

Hey guys, quick question, I ve got my 6BR shooting down in the ones and twos , and actually managed a few in the zeros at 100 yards, these are 4 shot groups. When I take it out to 200 yards groups open up to half inch to 3/4 inch. Just seems to me that they open up more than I thought they would at 200 yards, compared to how they are at 100. I realize factors like wind and such. Am I expecting to much?. Wondering what an average good group is at 200 yards,thanks.

What bullet are you shooting

What bullet are you shooting

Sorry,107 matchking.

.2 at 100 = .4 at 200 without wind or other influences.

Are you using wind flags?

Are you using wind flags?

No flags yet. I guess I better buy some and learn how to use them.

Old "rule of thumb" is that accuracy is proportional to the square of the distance. If you double the distance expect the group to be four times as big. Three times the distance, nine times as big.

I shoot 30+ matches a year at 200-300-400 yards with and against guns that are quite capable of ones and twos at 100 yards. Groups under 1/2" at two hundred are not unheard of but not common and this is with purpose built custom 17 pound benchrest rifles.

At 400 yards just the math would seem that a rifle that shoots in the high ones at 100 should be able to do under an inch at 400. In nine years and well over 10,000 attempts there have been exactly three occasions where someone has been able to shoot five 10's using a 0.9" diameter ten ring at all three distances. It's all about the wind.

At another club a 1/2" ten ring at 200 gives people fits.

Thanks, good to know. Instead of wasting barrel life and components trying to equal the groups at 100, ill be happy with what I'm shooting now.Again, thanks for the replies.
