As mentioned already. Both will shoot exactly the same! So just go with your gut feeling, what are you drawn to the most? When spending that sort of money you need to be happy at the end. It’s easier to upgrade the glass at a later date, picking up a good deal if you see one. It’s not as though you’re looking at shite glass. AI’s hold their value second hand, so would argue it’s important to get the rifle right first time.
The AX mag cut away for loading in the prone I think is neat and folding over the bolt is very useful imo. Initially I bought the AX because that’s what I wanted.... however at at later date bought an AT. Why because I loved the classic thumbhole look.
In my opinion the AX stock on the AT looks a bit Frankenstein and not quite right..... unless paired with the obsession chassis which looks perfect.
AT thumbhole or AX is my vote! But rest assured.... buying one, won’t stop you from wanting another one!
