Short projectiles require SLOW twist rates!
Long projectiles require faster twist rates!
Most '06 barrel twist, other than Palma rifles, come with a twist rate of 1-10!
Translation:
Not worth a schitt for accuracy with short bullets!
Yeah thats what l figured but tried em for the heck of it.
Had a Husqvarna once that would put 165 gr or 180g bullets into raggedy holes but drop to 150 gr and barely under 2" was it for all but IMR-4064 it would go 1.5".
