I am spending my winter working on developing a load for Garand competition next year. I am not looking for a recipe, I took care of that with an earlier thread on another forum entitled Garand Competition Loads. I am now in the process of testing the loads and need some advice. When testing 30-06 ammo for accuracy, is 100 yard groupings a good prediction of 200 yard accuracy? Or should I test the rounds at 200 yards? The reason I ask is it is much easier to see the 100 yard target with my spotting scope (saving up to get a better one) and it is much quicker to change targets walking 100 yards as opposed to 200 yards, thus avoiding ******* off the other guys at the range for taking too long to change targets. Thanks for the advice!
