RMR bullets ... Are they pretty consistent on weight and size?
When I shot USPSA in the 90s, my reloading and shooting mentor was a bullseye match shooter who was a stickler on consistency to produce sub 2" groups at 50 yards when I was trying to produce sub 2" groups at 25 yards. He emphasized the importance of component consistency which produces consistency of finished round's dimensions (He sorted bullets by exact weight and would scrape the lead base of FMJ when they weren't).
For my match loads, I used Montana Gold jacketed bullets exclusively (And no, I did not scrape the bottom of FMJ
) as they were more consistent than other bulk bullets I tried in weight (Less than 1.0 gr) and OAL/COL.
When RMR purchased NEW bullet machines with NEW dies to produce their in-house jacketed bullets (New dies and machines will produce bullets with more consistent nose profile/ogive than older/worn machines/dies
), owner Jake set out to produce very consistent match grade level bullets to go as far as being particular about proper lead alloy core mix to produce consistency in weight. On my Ohaus ASTM Class 6 check weight verified scales (Down to .06 gr/4 mg check weights), RMR jacketed bullet weight variance is often less than .5 gr.
With 115 gr FMJ, OAL variance is less than .003" using mixed range brass and .001" using pre-resized brass. With 124 gr FP Match Winner, OAL variance is less than .002" using mixed range brass and .001" using pre-resized brass. (Measurements were taken with .355" pin gauge verified FA dial calipers) -

Many consider Hornady HAP bullets (Jacketed HP without expansion cuts of XTP) to be accuracy standard/reference for match shooting. And IIRC, Zero bullets (Another highly regarded bullets for consistency) were used during the last great component shortage by Atlanta Arms to produce their match ammunition. When RMR started producing their in-house jacketed bullets, I did a comparison testing and below are my results -
