I put one on a Sako 75 SS in .308 Win. It did bring the weight down considerably. I currently have another order through our Gear Store for a Sako 85 Classic style stock for my 85 Finnlight .270 Win.
If you put a McMillan
Edge Tech on your 85 Laminate, you will not believe the difference. I really don't consider the .338 Fed a heavy kicker, but if you are concerned about recoil have a one inch Pachmayr Decelerator installed by McMillan
when you place your order. If most of your shots are no more than a couple hundred yards, I would think the 338 Fed would be fine with a McMillan
Edge Tech stock. You will never want to put the laminate stock back on.
