Not sure on this sight, but reloadersnest.com is good source. I would suggest starting there and see what you can find. Mind you, when ever you find other peoples loads, work up to them. Sometimes people post loads that work well for their particular rifle, but not necessarily safe for yours. There is some very knowledgeable people here that can offer some sage advice. When I loaded for .338WM about 15yrs ago I wasn't very successful. My cousin ended up loading for me. I was new to the game then and still learning. Hope to get another 338WM some day.
