I'm "old fachion" and will stay on 180 or 200gr Lapua Mega in my 30-06 for moose and wild boar hunting. Also it works fine for roe...do not see need to change to TSX as it didn't run well in my Blaser. But for next Africa trip will load my 9,3x64 Brenneke with 270gr Lapua Naturalis what by finn's fairy-tales is even better than TXS...LOL.
