Shouldn't take "significantly" more pressure. Check your bushing fitment and possible barrel alignment. HSS reamers will try and flex to follow misalignment. You said you had good chips......but you may have ran into some work hardening. Did the barrel feel warm?
Lots of real estate on 338lm.......I cut rpm down to about 80.
I think your experience is coming from something other than the barrel material.
