Minimum yardage for effective 1000-yard load evaluation and shooting practice?

[jeffreybehr]

I have read that the long bullets in high-twist barrels that are so succesful at 600 - 100 yards don't shoot particularly well at short--as in 100 - 200 yards--distances. How 'bout 300 yards?

I'm such a newbee at this that I've not yet SEEN a 1000-yard BR match, but getting into a shooting discipline that is extrememly difficult to practice makes little sense to me.

Is shooting BR at 300 yards good practice,but for the increased wind and mirage conditions at longer ranges)? I imagine I can find enough desert around Phoenix to shoot safely at 300 - 400 yards, but that might be about it except at Ben Avery, which I understand doesn't have a 1000-yard BR range.

Not sure that that is true at all. Mine will shoot in the point .1s at 100. That being in an 8 twist 6 br. I know it
would do better if I could.

Sometimes you will be surprised at 1000...a small group at 100 or even 500, and low ES does not guarentee you a small group at 1000yds.

i.e.: 10-shot group, 8fps ES, 12" high group at 1000yds.

105 scenar, 8.5tw broughton, 2850fps. Usually shoots 5-shot groups in 1-1.5" at 500yds,always under 1.5" of vertical) but strings vertically at 1000.

Why? not enough fps to get the right stability is my only guess.

In most cases, close range performance will be proportional, but not always.

OK...I think 2 guys just said that their 1K-BR rifles shoot VERY accurately at 100 and 200 yards, yes? So time and money spent doing initial load evaluation* at 200 yards will be well spent? So maybe I can reject loads that shoot poorly at 200 yards and then evaluate the good ones at longer ranges? BTW the caliber likely will be a 6.5-284.

Anyone else find this method worth the time...or NOT?

Use what you have...I know a very good shooter that does his load development at 200yds...he is in the Williamsport 1000yd BR HoF...

Heck JB I know 2 that shoot at 100 and just use a chronograph for all their workups one is a HOF shooter and the other is on his way. Heck Martin does all 100-200yd workups and uses a chrono and he does real well.

Bill...that is right, forgot martin shot at 200 also...George K is who I was talking about...

I believe Mark, John and the Hoovers also do most of their work at 100yds. The Hoovers may be different now with the other range being close to them. But anyway, there you have some real heavyweights in the shooting sport.
