I have been shooting 175gr. SMK in my .308, but was thinking about trying some 155's. I remember a post a while back, where somebody said that they where shooting a 155 load that would come close to the ballistics as a .300 WM as far as wind and drop. I couldn't find it with the search engine. anybody remember this? BTW what is the Ballistic coefficent of the Lapua 155's?

I used to shoot 175 smks in F/Tr. Now I'm shooting 155.5 Bergers. Think pretty much the same bc, w/ less weight, so you can push them faster. Works for me, w/ less recoil.

Re: 155gr. or 175gr.?
155's buck the wind better, have more retained energy @ 1k, and recoil less, what not to like about them, downside are Scenars are mail order only, and pumping them out at 3000fps will ruin your barrel faster.

I use 155 scenars from Superior Shooting Systems that have been Boron Nitride coated; they work really well even during Louisiana Summers and low country.

I use 155's for my long range loads. I have a box of 175's but I have not done a workup yet. I may just save them for my M40A1.

Also 155Lapua are more forgiving for unknown distance estimation errors
