Kurt, the Noslers seem to be ok for shorts, but a lot of guys were getting issues with them for longer ranges when they go into trans-sconic.
On the 155 side , there is nothing in it between the HBC Dyer Mk2 and the Lapua Scenar. Both are very good projectiles.
Personally I found the Dyers to work better with 2206H, shot superlongs with that combo until I changed to 185's
