My experience for the .308 is limited to two guns.
One is my S&W Husqvarna Sporter and the other a BLR. I use Lapua brass for them.

But to my surprise,I bought some Starline and it is heavier and more consistent in weight and measurements. Splitting hairs but I am going to use Starline. My son has used Lake City in 5.56. I am not impressed with lake city. Maybe he got a bad lot. I might have to go to Lake City 7.62 NATO if either gun tears the brass up two much.

I already have IMR4895,H4895 and AA 2495BR. I'll try all of them.Thanks

Gun Shows are almost as comical as boat ramps in the Spring.
