Ballistics? XM855 vs. XM193

[tpelle]

I've always used XM193 55 grain ammo in my plinking rifles, and use a 50/200 battlesight zero. Last night I ordered some more ammo and decided to try XM855 62 grain stuff. Will I expect to see a significant difference in trajectory out to 200 yards?

Depends on howmy you defineand "significant" My experience has been that my green tip ammo shoots about 1"at lower per 100m yards. If your looking to shoot "minute of man" 0-200 yards, then the change is not very significant at all.

Do you know how to use ballistic programs to calculate trajectories? Most of them are pretty simple. Hornady makes an easy one.
