Is this a hunting rifle? If so what type of hunting?
Or this a target rifle.
You want to dial a lot or BDC?
With 270 I’ll assume it’s a hunting rig. Most of my hunting rigs have 2.5/3.5-10, one has 3-12 and 3-15 is my biggest scope . I like to keep things lite. The 3-12 covers everything I need from the woods to the range. Especially once I get to 500/600 yards.
Big difference between hunting and LD at a range. I don't like the "trees" on any hunting scope and as a practical matter my hunting experience tells me that there's not a lot of dialling time or time to check wind before a shot.
For hunting anything over 12x is ridiculous as far as I'm concerned. A .270 is not generally considered optimal for long range, but of course YMMV.
