I just recently got some data for my 6.5 PRC. Used 127 LRX bullets with Reloder 23, BR2 and ADG Brass.

Avg speed was 3030fps. 53.5-54gr. BTO 2.310"

22" Rock Creek Pre-Fit from PVA.

ES and SD were terrible, but was <1/2" @ 100yrds.

I like RL23 for temp stability. New bbl so hope i can get close to 3100-3200fps. No pressure signs.
