Has anyone done any verification of their BC especially the 303 HC? Oh yes 45 cal.
I am looking at getting a ballistic turret from kenton for my NF ATACR.
I am working up my load to have it inscribed on the turret itself.
Thx

Yes But it's velocity dependent The 303 HC @ 2900 has a BC of about 400 at my elevation which is 1800 ft, after about 600 yds the BC starts falling off. I would verify with the load and environmentals you expect, it all makes a difference.
When doing a custom turret I always verify my drops at the range before having it cut.

for me I am close to sea level about 33 ft. But in my load development I am at 3066 fps with 303HC and still narrowing it down. I got 3 more loads to go. So far my sml is getting better at higher velocities. Going to 91 92 93 gr of 10x and see what I get. 90gr got me .3 at 3066 fps. This will be my hunting load and my dream deer hunt in Iowa in January. I am also in nj so funding any range over 100 yards is not easy |
