Help with One Scope for Same Rig to handle Different Calibers

[DBrickD]

Have a 8" 300blk bolt gun setup and getting a 12.5" 6ARC barrel and action incoming. Trying to see if it is feasible to get one scope and zero it for one caliber and use the holdover on the reticle for the other caliber, without having to zero every time I swap the barrel. For the 300blk, I would go out to 200yds and 6ARC will be 500-600yds and in.

Questions:
Is this doable with one scope and not having to zero between barrel swaps?
If so, do I zero at 100yd with the 300blk or 6ARC?
Any recommendation for a light weight 3-18x, 4-16x scope with the ideal reticle for this setup?

Thanks.

Honestly, that sounds like a horrible idea

What's your plan if the zero is off horizontally?

Just re zero the scope, things are gonna move when you swap barrels

He's goona hold for that as well

Ok. A bad idea. Looks like I will zero after every swap.

Could always get another scope/rings.

Yes. Was hoping to repurpose the Razor 1-10 to some other setup. Guess, depending on how many times I swap if it makes sense to get another optic setup dedicated to each caliber or just re-zero.

Unfortunately, barrels aren’t perfectly straight and any switch barrel gun will either need to be rezeroed, or have a separate scope for each barrel and get closer, but still need to be rezeroed.

Even custom barrels are somewhat banana shaped, and it’s not uncommon for gunsmiths to clock them so the curve points up, saving some elevation adjustment, but that curve can shoot in any direction in prefits or if the gunsmith doesn’t spend the time to do it.
