    Can I work up a .223 load in an AR at 25 yds?

    I know I can zero using the military target at that distance, but is that too close to know what my rounds are really doing?

    I'm thinking just because they're at the same elevation as XM193 at 25 yds that doesn't mean I'll have the same trajectory over the entire flight path comparing the two.

    Or if FPS is close and elevation is the same am I good to go?

    My intent is for my reloads to strike a target at the same POI at any range under 300M as XM193. Is a chrony & a 25 yd range going to give me enough data to do that or do I need to be testing at 50, 100, 200, etc also?

    As much as I'd prefer to be outdoors and shooting targets at distance, it's about an hour drive to a range for me so it just isn't practical. Even then, it's a 100yd range, but I'd think if I have the same drop at 25, 50, & 100 yds it would be the same out to 300M.

    Shooting over a chrony with bullets similar to m193 will give enough info to plot trajectory pretty close assuming you’ve got data from shooting the m193 through your rifle. 25yds isn’t going to tell you anything about grouping.
