Sounds nice, my 6MM all said and done are 485-490 depending on the arrow. My 5mm were about 505 grains all done with lighted nocks. Looking at upgrading to 125 grain brodheads for the 6MM FMJI'm using Gold Tip Traditional, 35/55 with 250 grains up front. 50gr brass insert with a 125gr Wensel Woodsman glued to a 75gr steel adapter. Shooting them out of a 47# longbow. Total arrow weight is around 435gr.
