RE: 130 grain vs. 150 grain (.270)
I handload Nosler 150 gr. Ballistic Tips in my .270 Winchester A-Bolt. All things being right, they will shoot into 1/2" at 100 yards. I use them on whitetail deer. I have tried 130 gr. BT's and haven't enjoyed the same accuracy as I get from the 150's in the same gun. The 150 BT has an extremely high B.C. which makes it a great long range bullet even though it starts out slower than a 130 grain BT. Knowing your guns trajectory and practicing at longer ranges will enable you to make a drop chart for long range shooting and that is where the 150 gr. really shines!
