I'm thinking of buying a .223 rifle for varmint hunting and since I normal do alot of walking as oppose to sitting when I hunting I was hoping you guys could give me some input as to what rifle is the better one. I've got it down to two choices, please I know there are others, but these are the two I'm choosing from. The browning a bolt hunter in .223 with a 1 in 12 twist or the tikka T3. I'm a lefty so I'm limited as to makers. The tikka come with the 1 in 8 or 1 in 12 twist? I have a tikka in 243 and it's a screamer. I was thing of changing it up to a browning. If you had to choose which one would you choose and why? If you guys own either rifle please fill me in on the pros and cons. Thanks. Jeff Camiscioli
