I'm looking to purchase a Tikka T3 Varmint in .223 within the next week or so. I am wondering which model to get the standard Tikka T3 Varmint in black(blued) or do I got with the T3 Varmint in stainless? They are both described as hammer forged barrels. So will the stainless varmint model have inherently more accuracy? I'm using this rifle for groundhogs and bench rest style shooting, looking for super tight groups. Also they mention a 1/8 twist and 1/12 barrel yet when looking online the 1/8 twist seems to be the only one available, does anyone have any insight?
