Hi Nick h
for me its the quality of finish on the Sako, the magazine is much better quality and it fits flush to the stock, the action is smaller for a .223 all much neater in my eyes, the action and bolt was super smooth on the T3 but one size fits all calibres. the bolt shroud on the t3 was cheap plastic( every one seems to fit metal replacements for the t3 bolt handles and shrouds-this is an extra expense , dont feel the need to on the sako)
i use my .223 for foxing so a heavy varmint barrel is wasted , excessive weight and no more accurate for my needs , sub 200yards under the lamp and for the amount of lead i sling down it is perfect with a thinner profile barrel, all horses for courses but suits mine fine
For me personally the sako wins hands down and is worth the extra few sheckles which i can afford by a little more saving and not buying the first gun i see, i would rather wait and get what i want when i can and keep the gun, i speak from experience as did this with all my rifles .22, hmr and .223 , i bought the first guns i saw and only after a couple of years do i know have the rifles i will keep , two Anschutz and two Sakos
