Gotcha. Yes these are with .25 Altaros ATP Smooth 49.5 grain. BC with G1 or RA4 is 0.21. I use equivalent G7 which gives a lower number of around 0.110. Never paid much attention to BC “spreads”. Same slug, same speed, same distance. Any deviations are from weather and wind conditions. The Altaros IMHO are by far the best slugs on the market.I ask because ive been doing a lot of shooting out to 260ys recently where BC std dev and ES matter a lot. I can get super consistent speeds but if my BC spreads are poop it is super obvious down range. Shooting patriot javelins with my dynamic produced these results and switching to zans was a huge improvement.
