[QUOTE="264MHC, post: 2037936, member: 111161"] The 6.5x55 improved (pretty much any variant) is an awesome cartridge. I have a standard 6.5x55 and my best load is a 135 Berger Classic hunter at a comfortable 2870 with RL 23 in a 24” barrel. I built my first improved with a reamer I designed with a 35* shoulder and a .200 freebore on a shilen dgr long action with a 25” 7.5 twist barrel. It runs 156 Bergers at 2980 with RL 26. I recently decided the medium length cartridge wasn’t fully utilizing the long action and put a 280 AI barrel on that gun. I then built a new 6.5x55 improved (264 MHC) on a tikka action with a 21” 7.5 twist barrel to be a light, handy deer gun. Haven’t shot it yet, just waiting on a scope, but I’m hoping for around 2850 with the 156 out of that short barrel. I use a 6.5x55 Lee Collet neck die, a Hornady seater, and a custom Whidden body die ($100). It took 4 firings including fire forming before I even needed the whidden to bump the shoulder. The time it took to receive the custom die was less than it took to get to the 4th firing. You should definitely consider it, just don’t put it on a short action. Let me know if you have any questions about the cartridge. [/QUOTE]
