Hello all, After my most recent post in search of rifle recommendations, and plenty of time spent researching, I have narrowed my search down to the Browning X-Bolt Composite Stalker in 7mm Rem Mag. I have also considered the Tikka T3x Lite, however I liked the extra 2" on the 26" barrel on the X-Bolt. I plan to use this rifle for mule deer, black bear, and elk out to around the 500 yard range and steel past this yardage. Now, my question... What's the heaviest bullet weight I can stabilize with the X-Bolt's 9.5" twist and 26" barrel? I had considered 168gr Nosler Partitions, however I am open to other recommendations. Additionally, what 20 moa bases work with the X-Bolt? Is this a short action or long action? Also what height scope scope rings for a 50mm scope? Thanks in advance!
