[QUOTE="squirrel_slayer, post: 2910608, member: 119695"] Being manually operated I'd definitely look to faster powders. I know red dot is popular for bulkiness but if you have TB that's probably as good or better. 7 twist should be plenty fine. 5" should get you close to 1k ft/sec with that bullet using a powder like red dot. Trail boss was way slower before case fill became an issue. Below is a quick snip of some red dot with said bullet. Going with a 7" barrel will maximize velocity at sane pressure levels with said powder. 6" might split the difference and keep you out of that transonic threshold. If you spinning up your own tube you could always start longer and see how it does then chop down till your happy then thread/suppress it. At the end of the day 1k ft/sec is 1k ft/sec. It doesn't matter if its a 5" barrel or 16.5" barrel the external ballistics are the same. Good luck and be sure to post pics of the build/kills [ATTACH type="full" width="992px"]496523[/ATTACH] [/QUOTE]
