I picked up a pound of RL-15 at the gunshow today because they had it.
I don't have a clue what to do with it for my .223. Any experience with RL-15? Looking at the charts it seems not suited for 55 grains. Anybody use it for 62 grains? Will CCI 400s work with it? Should I forget about it for .223 and save it for my .308? Any advice? |

Re-15 is great in 223.
My favorite load with it is AeroE's accuracy load, Win case, 27.0 grs Re-15, Sierra 52 gr BTHP, Rem 7 1/2. Unlike Varget, it will throw thru a powder measure, as it is cut shorter than Varget. Any primer suitable for 223 will work just fine. Have you checked the on line data? |

Reloder 15 is a great gunpowder for .223 Remington.
It's on the slow end of optimum burning speed for bullets around 55 grains in weight, but that doesn't mean it won't work. The case will be full of gunpowder. For example, I shoot lots of 52 grain MK's with 27.0 grains of RL-15. The gunpowder will fill into the bottom of the case neck in a Winchester case. I've used up to 27.4 grains but this fills the case to top of the case mouth and it's hard to keep from spilling gunpowder when handling the case. 26.8 grains is too small and doesn't swell the case mouth enough to seal the chamber well. This load produces over 3200 fps, so I always have to ask, "How fast does it need to go"?; the speed is close enough to those possible with slightly faster gunpowders. So, my recommendation is to use RL-15 for bullets from 52 to 80 grains weight in .223 Remington. |
