Both Norma and VihtaVuori have online manuals with 338 data.
The load for the Ballistic Tip is my own however.
Be careful not to switch brand of brass without working up the loads again.
The Norma cases show signs of high pressure before the Lapua do. I only use Norma brass due to the price; it's only half the price of Lapua in my country(Denmark)
The recoil is severe when shooting from prone. I use a piece of thick foam rubber between shoulder and stock.
Sometimes i forget to bring the rubber to the range. Those days I don't shoot much.
I use a Swarovski 6-24x50 with TDS reticle. Thank God for the telescopic eyepiece
The only thing I would like to change is a 27" barrel instead of the 24.5" which is standard on the Scandinavian model.
I can higly recommend this rifle
