The Bergers were iffy as to expansion but the SSts did expand. In my tests, mostly into wet Montana mud hollow point bullets tend to bend at long rang and not expand. I try not to use hollow point hunting bullets past 300 yards. Now for 6ARC I believe you will be hard pressed to reach 300 yds with any bullet and still retain 1000 Foot pounds, which is the old standard for deer size game. New bullets and fast twist rifles may be an ecception for that 1000 LBS rule and may perform at lower velocities. You'll just have to find some Montana gumbo mud to test in- Ha, Ha!
22" bolt gun mind you. Getting 2780 fps at the muzzle with the 108 grain Elite Hunter. Berger calculator is suggesting the bullet is still delivering 1004 ft lbs at 500 yards. This based on my average hunting elevation of 1800 feet above sea level & a 30 deg day that would be common for deer hunting weather in a common area I hunt.
If the elevation was changed to sea level Id back off to 450 yards to achieve 1026 foot lbs on target.
