When fielding a M4 ( 16" ) using a zero of 50 yds and XM193 ammo, what would the following ammo be expected to print.
IMI 855
BHA 75 Match

Info appreciated.

At 50 yards you'd be hard pressed to tell which ammo you used.  Once you start getting to 100y and beyond you'll see some differences in drop AND in drift.

I apoligize for being ' short ' on my question. I should have been more pecise and said after zeroing at 50 and then moving out to 100,200 and finally 300. Is there a way of determining the flight of the subject rounds or would it be better to just shoot the rounds listed and make a log.

If, I understand what you're asking, you're saying that you have zeroed your carbine using XM193 at 50 yards.  You then want to know what the points of impact for different loads would be, fired from the same carbine without changing the settings on your sights.

The only way that you are going to find this out is to shoot those different loads from your barrel.  Your question, (for the most part) is not one of exterior ballistics, otherwise you could just use an exterior ballistic calculator to find your anwer.  Your question involves interior ballistics; specifically recoil vectors and barrel harmonics.  These factors are going to be different from barrel to barrel and are not something that can be easily predicted.

Thx for the info. I guess I am needing to shoot those rounds listed ( and more ) without changing sight settings. This will begin my science project and after gathering necessary equipment ( to eliminate this shooter ) from the equation.

Logbook is the way to go.
