Vertical

[BradY]

No thankfully I dont have vertical problems at the moment- thats not what this is about. I know there have been numerous threads on setup, technique, tuning etc to eliminate vertical from groups at long range. But do others find there seems to be vertical encountered more so in a fast twist and long for caliber projectiles than a slower twist and shorter for caliber bullets. Im no physics scholar, but is this correct and why would it occur? Would like to hear peoples experiences and opinions.

Long range shooting and light bullets don't go together.

155 palmas , considered light, slow twist. 185-215 bergers fast twist.
Lot of people succesfully shooting the 155's?

Thats a given.

Compare say an 80gr in 1: twist 22BR and a 155gr in 1:13 twist 308. Both rounds more than capable of making 1000yds in 30 inch barrels. Why would the 80gr show more vertical side by side compared with the 308 in a headwind when both are comparable in accuracy in calm conditions.

I dont consider 155's as light bullets. Light to me is something that will carry to 700yds and go subsonic. But im talking short and long bullets for caliber. 155 isnt long for 308 but 80gr is for 224.
