Interesting note regarding rpm, chip loads, and feed rates.
I worked with David Kiff very closely for three years getting this right.
It's a matter of how the reamer is supported gents. At Nesika we were able to chamber up to about 1200 rpm with carbide tooling. I'd run HSS reamers at about 300-400 with no ill effects. No burnt cutters or chatter.
Surface finish was excellent. At first we used nothing but gray scotch brite for fluff and buff afterwards. Later we decided to clean up with 320 just to put a cross hatch pattern in the chamber so that the brass would bite down better in an effort to reduce flow towards the neck and shoulders. 320 was about right because it didn't "frost up" the brass. I'd shoot for the same pattern typical of any well honed cylinder bore on an engine.
TIR varied between 175 millionths and a tenth.
I know many my be compelled to want to call BS on that, but its gospel truth.
Granted, I had up to 2400lbs of coolant pressure for chip evacuation at my disposal (very snorty rig that I ginned up over the 2005 Christmas holiday break) and a 6500lb machine, but we NEVER used the tail stock. Experiment with holding your tooling on the cross slide. You might be surprised what you get.
All I will say is, MASS and PRESSURE counts.
good luck.
