Should do well with the 150, once you go lighter I prefer the Accubond and for over all performance the 140 Berger has treated me very well in the 270 Win but we mostly load the 165 Matrix. I do use the 150 BT as a last ditch effort bullet, if I can't make it shoot then it's over haul time!!
Nice, because I to have a Tikka T3 left hand Lite, I to use 150gr ballistic tips Mine to shoots very well…. I’ve taken Sambar deer with one shot out to 251 yds.. in fact all me 5 deer I have shot with 150s, ALL WITH ONE SHOT they work really well in 270
I've got both a lh tikka t3 stainless in 270 and a marlin xl7 in 270
both eat the 150 hornady interlock with 56.5 I 7828 and a wlrm like candy.
The marlin just shot a .3" group up at 100 with that load the other day. That rifle HAS to be fouled before groups. The tikka doesn't care.
the nos 130's work well with rl17 in the tikka, but the marlin hates them.
haven't worked with the 150 bt yet.
