[QUOTE="north of 53, post: 627965, member: 8510"] "So what is the proposed theory on why this is the case? I haven't noticed or heard of this in any caliber unless you bring in twist rates and other factors that affect bullet performance. Scot E. " Excellent question and as I said it is not a hard and fast rule, but there a strong tenancy to favoring velocities in those ranges. I have noticed as I am sure many have ,that most guns have accuracy nodes at different velocities.
