PSP's, they were 6.5mm, I haven't noticed this happening with the 165gr .308's that I bought, but then again I really haven't had a chance to put many through my 06, except for load development. The thing is like I said in the post, the load using I4350 was grouping and average of 1/2 to 3/4 inch, using winchester brass and wlr primers. The H380 loads were grouping somewhat larger but with the right powder/primer combo would probably tighten it up some. Now I'll only use the Corlokts for the range and not for game.
