I took delivery of a new to me 300WM today and have no idea where to start. It’s a 28” Bartlein 1:10 throated for 230 Berger OTM’s and the original owner only shot H1000 in it.

Problem is I leave in under 2 weeks for a bear hunt and don’t have either 230’s or H1000. I do have several hundred 208’s ELD-M and several pounds of Retumbo left over from an old 300 RUM.

Might anyone have any decent data for this combo?

any insight is appreciated.

My load is 77.7 grains with both the 208 hornady's and the 210 SMK's in Federal brass. You should find a workable load somewhere in that area.

I had a 300wm and now a 300 Norma. I've shot Berger 230s,215s,245s, 225elds, & 230 atips. The 208 seemed to me to be the least finicky of them all. Not saying that the others were finicky but they just wanted to shoot. Im sure there are multiple nodes but if you can get those 208s up to somewhere around 3050-3060 fps, I think you will have a dandy grouping load.

I run 215gm and cci 250s. I haven't noticed much difference performance wise. The 215gm has a thinner cup and will flatten upon firing easier than a cci 250. WLRM is the hottest primers I have ever used use caution if you ever decide to try them.

I did found this :
208 touch lands at 3650
So my coal must be 3640

210 touch lands at 3573
And my coal must be 3563

Right ?

I will try to load from 79 up
I will increase 0.5 grain for each charge
I will make 3 pcs / charge and i will try to find groups.
