    Hey guys, I'll be loading for 300WM, 190MKs, WLRMs, and would like to use RE22, being that this is what I've heard is the best powder for the WM, any suggestions for a starting load? Thanks, Jay

    Jay, start at 66 gr, 67.5 gr if you are shooting a moly coated 190.

    My all time best load for the 300 win and 190 gr SMK's is 71.5 gr of IMR 4831and a FED 215M primer. I set this .005 off the lands. REMEMBER THIS IS A MAX LOAD, START AT 65 GR'S AND WORK UP.It gives me aprox 2700 fps in my rifle. Hope it helps.

    I'm using 71.0 grs. of RE-22 with the 200 gr. Accubonds in my 300 WM. (worked up to of coarse) Will be trying to work up to the same load with the 200 gr. MK as soon as I can get some range time in.

    I'll second the suggestion for H1000. In my rifle 77grs with a F215 primer shot real well but was a little warm. Start around 74-75grs and see how your rifle likes it.

    If I may pipe in with a tertiary response, the H1000 works GREAT with the 200gr SMK in my rifle though I have used it minimally with the 190's as I can't get these to shoot very well out of my rifle. 75 grains seems to be the most consistent load. I use 75grs. H1000, a CCI LR BR primer (no, not a magnum primer), WW Ni plate brass (culled by weight along with bullets), cases trimmed to 2.610 +/- .0005, chamfered, neck turned, and the COAL set to 3.553" +/- .0005 (about .002 off the lands in my rifle.) The action is a Howa 1500 and the only work done on it was a trigger adjustment that I did. No blueprinting or trueing has been done. The rifle still sports a 24" factory bbl (1:10" twist). The action and bbl are bedded in a factory Weatherby walnut stock and looks sweet. As is, this rifle prints .75 - .59 MOA groups easily. I can only imagine how nicely it will perform after putting on a Pac-Nor SuperMatch bbl and trueing the action! Point being with all the details is that, in my opinion, the 300WM is one mighty fine long-range cartridge and it is very easy to load for. My 300 will be my primary hunting rifle this coming season hands down! Best of luck to you!

    66 grains of IMR 4350 with a WLR is a known accurate load with the 190, since 1966 or so. Different powder lots require starting at 65 grains and working up. In my tight chambered and short throated rifle, 2900/2950. Works for me.

    71 grains of RL22 with a 210M works relatively well.

    72 grains of N165 and a BR-2 works relatively well also.

    Start below and work up though.
    Good Luck.
