What works for some doesn't for others this is what I load for my .243 a 70grn Blizking bullet with 40grns of ramshot big game powder behind it as we no some guns like different bullets weights the Op might be better waiting until he gets a gun and try it first to make sure it will shoot that weight of bullet I have been down that same route buying boxes of bullets before I had tried them allot of time and powder used good fun but very frustrating at times
