I just finished loading 1000 of the RMR 124gr HP bullets and have shot about 400 at the range and during a match.

And you can see how "blunt" the ogive is. RMR is purposely trying to increase the full dia portion of the bullet to increase contact area with the lands. They are doing that to differentiate themselves from everyone else with a "me too" hollow point. Other than that, these are VERY well-made bullets with a high degree of finishing and inspection.
However, I also notice in the Description section that they seem to have done expansion testing on this bullet and recommend 1100fps (min) to get the full effect...
We?ve been testing them for a while in calibrated ballistics gel and results have been very promising. It is recommended that you shoot them at 1100 FPS or more to get reliable expansion for self defense or hunting purposes.
? If I was loading my own SD rounds, then I would sooner trust the Gold Dots. I say this because the Gold Dot testing has been far more rigorous, and being a thick plated bullet (rather than a traditional jacketed) the Gold Dot is going to retain more mass as it expands. At $14/100 the Blems they offer become a really good deal.
? If I was going to load an
SD practice round, and try to mimic POI and felt recoil of my chosen SD round, then the RMR bullet described above would do very nicely.
