What distance to test reloads?

[palerider]

When working up a new load at what distance should i be shooting at to find the best charge? Does it matter?

I work up at 100M then after I have a load I test it at longer distances. If my plans are shooting 1,000 I will take that load and shoot it at 1,000. I like shooting the loads at the distance I will be shooting them to ensure they will act like I want.

I do my testing at 100 yards over a cronograph and then take the best load and move out to longer range to see what it does.

200 is better than 100.

I test my reloads through a Oehler 35P to 300yds,600yds & 1000yds.

If conditions are perfect I'll shoot at 300yds over the chrony. If not then 200yds. Boattails take that far to stabelize. Then the smallest ES and SD will move out to 1k with tweaking seating depth to tighten group.
