I spent a bunch of bucks trying to get the 150 SSTs to shoot in my LTR and PSS and they just don't do well. With the LTR 150gr Ballistic Tips do really well with 44.5gr of IMR-8208 using Lapua neck sized brass, Fed 210 primers and and OAL of 2.891". The 155gr SMK also works well with the same load.
