I just picked up a reamer that says 284 win Match 313 nk 0 freebore. Can anyone tell me what bullets will work with this 0 freebore reamer. Ross rem40xb1@msn.com

You'll probably will need a throater to go along with the reamer as zero free bore will have a very shallow throat, lead. My 7/300 wsm and 7 wsm reamers have .170" free bore and are for the 168/180 VLD Bergers.

Cut a chamber in some scrap and secion it off so you can experiment with it.
Zero freebore makes some sense in a "Match" reamer. Suppose you start shooting when the 180-gr Berger is popular. That is a long bullet; takes a lot of freebore, and you have a reamer ground with the freebore for it.
Days (weeks, months) pass. Now, for some reason, your rifle won't shoot the 180 -- or more likely, everybody decides a new bullet, say a 140-grain whatever, -- is the cat's pajamas. With the freebore needed for the 180, you can't shoot the new bullet without too much bullet jump. You need a new reamer for the new bullet.
So, from that perspective, a reamer that has no freebore is a plus. For an extra, one-time $75 or so for a throater, you save the cost of a new chamber reamer when you decide to change bullets.
BTW, I'd check to see if it is "zero freebore" as opposed to "zero throat." If only the freebore is zero, you will still have a leade angle -- probably 1.5 degrees half-cone angle. In that case, your throater should have the same. But if it is "zero throat", there will be no leade, and you can use whatever leade angle you want on the throater -- or get several throaters with different leade angles, if you want.
All this planning ahead might sense to a full-blooded competitor,esp. one with tight pockets who doesn't want to spring for a new reamer with each change.
Finally, I'd recommend the kind of throating reamer that can be used with a T-handle as well as a lathe. We do most of our throating with the barrel installed in the action, using a delrin guide for the T-handle, and a stop to get the length of the throat just right. Others may prefer to cut the throat when the barrel is first chambered, i.e., stil in the lathe. Again, just more options.

284 Reamer
This reamer is 0 free bore. I wanted to use 120-140-150 grain bullets on a xp100 pistol. The barrel is now a 7br and shoots very well. I wanted to try the 284 for more horsepower. I plan on shooting a Moose with the pistol this year. I can send the reamer back and get a different one if that is a better idea Ross

that means you will have to turn the necks ....and is it a true 284 Win. chamber...if so the Lapua 6.5 x 284 brass will prolly not fit corerctly....points to ponder...how much time and effort do you want to spend on brass for a hunitng pistol......hope this helps answer your ???....Roger
