260 Rem loads for 100-600 yds & beyond

I'm looking at the 105 & 123 Scenars but i'm curious if the 105 is better for the shorter ranges from a stability standpoint. Does the 123 or 139 take beyond 100 yds to stabilize or not? Does the 105 have an edge over the 123 at any range up to 600 yds? Barrel is 26" 1:8 Broughton.

As far as reaching out to 1K does the 123 have an edge at all over the 139 scenars..or the other way around? I have some 142 SMK's I want to try but just want input from those with experience. I'm just skeptical of the 123 at 800-1K but I will try whatever.

In that 1 - 8 twist, it will be hard to beat the heavy bullets, normally. Some rifles exceed that rule. Some shooters will shoot the lighter bullets but alot of times their twist is less also. It is my belief that the heavier bullets will be more accurate at the long end in the 1 - 8 twist. Bill

Yeah, i'm just wondering with the 1:8 twist, will the 123's be any more accurate than the 139's, especially at shorter ranges?
