I don't. I would expect it would have been made with more freebore than say a 1 in 12 but never assume. Contact them and tell them what bullet you wish to shoot and they will know what freebore will work for you. Another way is to load a bullet to the distance you want without powder in the case and send it to them. They will then chamber it with the proper freebore for you.
Good advice - unless the OP definitely wants to shoot a heavier, longer, high BC bullet. At that point he is seating the bullet past the inside of the neck, thus limiting case volume and muzzle velocity. There is also the potential for the pressure ring on the bullet to be beyond the neck and high pressure spikes if the cartridge case develops an internal doughnut. Also, for many average hunting situations it could be several years before one has to account for throat erosion. All valid considerations, including your zero freebore preference.In my humble opinion, you would be better off with a shorter freebore. WHY??
Heavier bullets seated out further to get closer to the lands, before too long (as the throat wears) there won't be enough bullet in the neck.
ME? ZERO freebore?? Start with lighter bullets and go heavier as the throat wears, and it will.
You find the sweet spot when seating, throat wears and next thing you know, sweet spot is gone because throat wore. Best to go short from the start. Don't like it, go longer with a throat reamer but you CAN'T go shorter. (without a chamber re cut)
