What kind of vlocity increase or decrease are other people seeing in the newer RL 15 that is marked made in Sweden for New River Energetics?
With my 9.3 X 62 with 286 gr bullets my old load of 58.5 gr of RL-15 was consitent 2350 -2370 FPS. With NRE version same load 2410 - 2420 and loss off accuracy till I dropped load to 58 grains.

NONE. i dont think .5 grs is a big issue. it probbly has more to do with LOT numbers,

how about the reloader 15 marked ,made with pride in the USA. Still trying to determine if there is much difference in the Sweden variety.
