I will have my 18.5 inch 6.5X47 Lapua back from my 'smith in the next few weeks and am wondering if H4350 and RL17 are gonna be a tad slow for that short a barrel. I have H4895, RL15, Varget and TAC on hand in abundance as well as a pound each of H4350 and RL17 to play with. Should I start with Varget or the H4350? Anybody run 4895 in the x47? What says the hive? Gonna be running 123gr Scenars and/or AMAX's.
