I remember, it was Al Miller who wrote that intro. "IF" I ever loaded a round out that far ( assuming the throat/magazine are right for it) I would definitely crimp it with a LEE FCD, ha. I am one of those that uses it on a lot of rounds, but I like at least a bullet diameter length in the neck. I feel it helps with run out, etc. Of course, we are talking about a hunting rifle and that intro is around 40 years old, lots of great powders/bullets for the old dawg now. My only experience with the 8x57 was a full dress K98 battle field pick up ( from Russia). It has Nazi markings, etc. I had a taller front sight blade put on it to facilitate zeroing, but kept everything else stock. I found a case of Turkish 8x57 machine gun ammo. Wow! That stuff is not only accurate but really moving out, ha. Corrosive too, of course. I ended up giving it to a young man in my church. I see the Huskies every now and then and they have the drop for irons. I bet those things slap you face pretty good, ha.
