    Friend of mine asked me to load some 338s for him and asked for 6 each at 73, 74 and 75 grains of R22 with a 250gr. Accubond. When i seated the first bullet to MOL in the 73s it was very compressed and of coarse the 74 and 75 worse yet. All my books are older and I have no data for R22 in the 338. Is this normal in this round or are those loads to heavy? Thanks

    I load 225 NABs in my .338 WM. My Nosler 6th edition only shoes 250 NP with max load of 75 RL22 at 112% load density volume based on 3.34" COAL.

    Be careful/safe.

    Bustr, +1 on the compressed load. I loaded Nosler Partition 225gr for a friend's 338 Mag and the top performing load was compressed. Must be the 338 norm.

    the only loads that really work good in my 338 are compressed. I use 250gr interlocks on top of 75gr 7828ssc. any 250gr is going to be long in that stubby WM case so they'll compress quickly when loaded to book coal

    Just for voice of reason, I have always been very careful when loading ammo for rifles that I do not own. A friend of mine had me load him some 210 grain TTSXs for his 338wm, and I gave him a starting charge with RL19. Made him feel tough that his big 338 wm didn't kick the snot out of him.

    Maybe you could load your buddy up a few extra rounds at lower charge weights just to be safe?

    Thanks for the replies gentleman. After reading this and finding more info it appears this is the norm for the 338wm with a 250gr slug.
