Is this right? I always thought, at least for a centerfire, that it took the bullet 100+ yards to stable out and after that things were more consistent. So, you can sight in one day at 100 yards and the next day with different conditions, you may have to adjust things. But if you sight in at 200 yards things remain more consistent, because at that distance the bullet has stabalized.

I haven't tested this at all, just what I remember reading somewhere years ago and it always stuck with me.

One of these evenings, I will push one of the Bullshops into the barrel and out and see what kind of engraving I get. I will do it on all 3 of the Ultra Mags and see if there are any differences at all. That will be interesting.
