CZ 455 Varmint, .17 HMR factory proof round
Posted: Sat Mar 31, 2018 8:32 am
Hi guys. I have a new one that just occurred to me. I found the target page that CZ ships with their rifles in the plastic sleeve, but never gave it much thought.

Note: This image was cropped and resized, exactly to 2.75 inches in diameter to accurately represent the same diameter circle on the printed version I have from CZ. Their scale is identical.

So if I understand this correctly, at 50 meters, (54 yards), these 5 proof rounds are are all off center of the cross-hair on the target, and the dark filled in circle is the "mean point of impact", or average distance from each of the 5 rounds that are un-shaded.
QUESTIONS:
1: Assuming these 5 rounds were fired at 50 meters, (54 yards) without the use of a mounted sight-scope etc, would you expect a much tighter group at 50, or 100 yards with a scope?
2: How are these rifles test fired with proof rounds in the factory?
Do they use a rest, a temporary sight etc?
