Give Dave Kiff at PTG a call. He has all the low down on reamers.

I have one of Dave's 22 match reamers... it has made some fine shooting Sako's and Anschutz's.
IMO, the only significant difference in the reamers is whether or not it has the rim cutter.
The "PTG Match" reamer I am using has the rim cutter. You run it in until the cutter just barely touches [ or even back a thou or so, ie not touching ] the rear face of the tenon and you are done other than any polishing and leade work that you may wish to do.
Some of the other reamers do not have the rim cutter so you must have some way of measuring and controlling the depth of the chamber [ the depth of driving band engraving is what you go by]. You also need to add a tiny chamfer/radius on the back of the chamber. This radius is automatically cut by the above reamer that has the rim cutter.
ETA: Kiff will happily email you a sheet that has all the specs on all the rimfire reamers he offers.
