Hold overs are a lot less precise than dialing, especially if you are talking about a duplex recital, one with mill hatch marks makes it doable. It will still be a lot more of a learning curve. 400 yards is about the limit of where it is feasible.
What is your current scope and cartridge?
True, but I also hunt enough that Im a "MOA guy--Minute of Animal"
Im able to routinely shoot out to 450 and do so often. And I have several calibers in Ruger m77, Rem700, Tikka T3x's with FFP scopes.
I know guys on RokSlide crap on them. (If it aint a 223/6mm, with a RokStock, Tikka with a Nightforce or TenMile scope then guys crap all over anything else.)
But I'm a Vortex guy. Never had an issue with them and I like their Christmas Tree retical with 2MOA increments. Also had deveral binos from them and very happy with the value & bang for your buck. Most of my scopes are Diamondback Tacticals. I realize they're exposed turrets, so I tape them with electrical tape. I dont have the budget maybe some guys do. But its never failed me and every time Im sighting a new one in, or re-verifying zero before a hunt, they have always tracked and am very happy with them.
My "one gun" that Ive put money into is my Tikka 300 win mag, and that is topped with a Nightforce SHV with the F1 reticle. Thats what I took my elk with last year.
To me. Dialing probably is more precise, but Ive been on hunts where animals are moving and I have to wait for the to stop and by the time I'd have time to dial, they move. Ive had it where I see em and barely have enough time to range let alone move my turrets.
I also worry about bumping them like.my brother did and not knowing.
Again, i like to keep it simple.
But Im also the guy still driving a 2004 truck with regular radio and a CD player. If it aint broke, don't fix it.
