I recently came across a Browning A-bolt at a very good price, so I decided to make myself the proud owner. It's a stainless model in 7 rem mag. Also has a 26" barrel and does not have the boss on it. Anyways, how far have you guys stretched an A-Bolt out to? I'm hoping to reach the 600 to 700 mark with ease. Further would be great, but we will have to wait and see.
