Rainshot: I am also puzzled by your contention regarding "scarring" by Remington 700's "in caliber 223 Remington"?
I have been shooting Remington 700's in caliber 223 Remington for over half a century now (54 years actually) and have NEVER had a "scarring" problem interrupt my shooting sports!
I just checked my inventory and I currently own and shoot 11 (eleven!) Remington 700's in caliber 223 Remington and to date no "scarring" issues have affected me what so ever?
The only Remington bolt action Rifle I own that uses LaPua brass is a Remington XR-100 though - and it also does not suffer "scarring" during its operation.
How does the "scarring" you endure with Remington 700's in 223 Remington affect your shooting?
I remember as a young man when Remington introduced the 223 Remington cartridge - it first came out in their Remington 760 pump action Rifles IIRC. A couple years later it came out in the bolt Rifles (again IIRC).
Long live the 223 Remington cartridge.
