Re: 338 LM Test Load Distance
Sierra does all their testing of this bullet at 200 yds, and they generally shoot quite well at that distance. But, as several others here have already alluded to, you need to do your testing at whatever range you want to use the bullet. Sierra does almost allof tehir testing at 200 yards, sort of a default distance. For load development, howver, just because a load shoots well at 200 yards, doesn't necessarily mean it'll shoot well at 700, 800 or 1,000 yards, etc.. This is common knowledge to most Long Range competitors, and a real pain when one doesn't have reliable access to a range that handles these distances (like here in MO, for example!) Do your inital workups at the shorter distances to weed out those that are obvious flops, but take the time to shoot the better candidates at the longer lines you actually want to reach in the field. Only way to know for sure.
