I've got a .308 and a .243 Steyr Scout. I use the same Swaro 8x56 with QR mounts on both. POI is only .75" left or right different between the two at 100y when I swap the scope over

Difference is, with the .243 I can watch the bullet strike, with the .308 I can't see anything.
I feel guilty shooting Muntjac and Roe with the .308. It's just ridiculous overkill. Chest shots on Fallow and Reds then I'm happy with it but I always end up thinking "if I'd had the .243 with me, I'd have felt confident enough to shoot it in the neck instead!"
I'm not going to sell it, but I wouldn't say its a patch on my .243 for British quarry.
