OK, Ive narrowed my new scope choice down to Swarovski. (I'll buy one when the cheque clears from selling a kidney) Either, 3-18 x 50 or 2.5-15 x 56. Prob the later but, there is a nice second hand 3-18 on the site. Any advice on choice, also is it worth having the Ballistic Turret? Please note this is for a stalking rifle and not for target shooting. I am mainly woodland but, I do get the odd hill and park invite, hence the preference for a variable scope. It's to go on Blaser R8, 308 and maybe cross over onto the 22-250 barrel. Is there a noticeable difference in light gathering in the two scopes? So if anyone has experience of both, please keep me right. Cheers fellas.
