I have been saving all my .303 brass for many years and started looking around for flat based bullets. The best i can find are the Sierra pro hunter 180 and 150 grain. 180 grain, being pretty similar to the the 174 grain Mk 7 cartridges , I'm assuming i'll be able to recreate them quite well. Does anyone in North America have a recipe for reloading the 150 grain bullets that gives a similar trajectory at least over the first 300 yards or so (so i can use the standard sighting)?
