Does anyone know of one? Pacific Too Group says they ahve one, but... no product # is listed

All the reamer makers should have them. Just call and tell them what you want. I use Dave Manson's reamers mostly, if he didn't have one on the shelf he can make one in a couple of days.

If your going to do it, specify the K31 reamer and not the 1889 reamer. Also Redding dies are the only ones I know of that make a die for the K31 and not a generic 7.5 x 55 die.

What's the difference betweeen the generic 7.5x55 and a K31 reamer?  I had thought the Swiss round was pretty stabil..

[kwells2006]

it may be the same... where can someone get a K31 reamer?

[kwells2006]

the K31 is 7.5x54.5mm if I'm not mistaken?

The K31 has a little different specs than the 1911 spec chamber. If you have a K31 and use the standard 7.5x55 die, it will oversize the brass, making the brass fit a little looser and reducing case life. The reason most have the 1911 spec die is the round will fit both chambers, where the true K31 Redding dies will not size the brass enough for the 1911.  If you check out the Swiss rifle forums, you will find out so neat stuff about these guns. An afterthought, since you can neck up .284 Winchester brass to work for a 7.5x55 a 30/.284 Winchester reamer might be easier to come by.
