FWIW, I tried the 150gr BST in my 7mm Rem Mag not so long ago. I couldn't keep a group under 2"....that's completely unacceptable to me....especially for "Supreme" ammo that costs $27 a box. I went to Kmart and bought cheap 150gr Power Points.....averages about an inch or less MOA. I couldn't believe it, but it worked out. I've never gotten lucky with factory loads, but it was too late in the year for me to buy the dies and components and work up a load.
