Never seen a Ruger not pinhole the 105's thus far cited(A-Max,Hornie HPBT's,Skinners and Berger). I'd be curious to know the powder(s) used and the muzzle velocity,at which stabilization was compromised? New one on me.
A) Never seen a Ruger or Remington not kiss 105's,in their OEM form.
B) An OEM Remington 2.8"-ish box will do it all and easily,especially when throating to one's whim and brandishing that finite control.
C) I'd not care to go 7.5" in a .243"...especially for a [bleep] SMK.
D) Very easy to add COAL or setback,again as per whim. If you are building,a DBM can often be a nice thang for many Blood Sport applications and you can get to 2.98"+ on a S/A 700 very easily there.
I concur that the Creed is yet another Goat [bleep]. The larger vessel will always make greater velocity,at like pressure levels and will reward one with diminished wind drift,which don't hurt equations outside a Tunnel.(grin)
A SAAMI 243Win is a very tough one to whoop,due it's Precision,Fun,Logistics,Ballistics and Pile Driving Ass...in no particular [bleep] order.
