300 wm load recommendation for 178 and 208 amax

[armike]

OK I have picked up some 178 and 208 amax's for my 5r Remington 300 wm. I have h4831sc, imr7828ssc and reloader 22 to work with. What's your experiences? Thanks

This is load for my factory R700 Sendero 300WM:
HDY A-Max 208gr., THUN case (swiss made), Federal 215 GM primer, Hodgdon H1000 79,0gr., COL: 3,63". Load is working to my full satisfaction. No problems out to 1600 yards (20" steel torso). H4831 didn´t worked for me but every rifle is other. Maybe you ll be more lucky. I would try Reloader 22 or IMR7828SSC... just my 2 cent.

Thanks for the advice.

my 208gr Amax load is similar to above, H1000 76.5-77.0gr depending on lot, 3.6" coal,FGMM 215M, nets 2970fps (Sako TRG so roughly 27" IIRC also 1:10" tw) with ES/SD in single digits-usually 9/6fps. I have also run non magnum primers with nearly identical results. I have been using Win brass, a tiny bit of RP with the same load, some day I'll probably pony up for some RWS or ??
Has worked very well at holding vertical and transitions well through transonic.

This is shot at 300 yards and a five shot follow up later shot 3/8" at 300 as well Velocity is 2864 fps.
