Re: 155 grain 30 cal Lapua or Sierra
What are you trying to do with it?
I bought 300 155 Scenars a few years ago, and went through all of them trying to get them to shoot. IMO, 155s in a .308 is a finicky little bullet with a weird Secant Ogive that I found to be very tempermental in regards to seating depth.
Some people love them, but I have found it much easier to get Tangent Ogive bullets to shoot, and even Berger VLDs with their hybrid type of nose.
I never bought another box of Scenars.
Anyway, is there a particular reason you chose to shoot 155s?
