if your bullet design will take the stress 2400 seems to be a good accuracy node for just about everyone.
Don't own much of a selection of the small caliber, high velocity 'tools'. Would have to go straight to a slightly light for caliber '06 bullet.maybe in the East.
shots can get stretched out pretty far here, the 243 with 58-70gr bullets is probably the top option for most serious chuck shooters.
I use the 58gr V-max in mine, or step up to the 25-06 with 86gr bullets if I have one I really can't get close to.
usually the 223 in the AR rifle and a lot of spot and stalk patience is what I use.
