Ok I have tried several bullets of different weights and powder and so far H1000 with a 190 smk works well (needs fine tuning ). Runnin 79.0-79.2 gr H100 , FED215 MP seated at 3.440-3.490 . I also tried the 240 SMK amd it worked better than expected . Runnin 65.5 gr H4831SC , FED 215 MP seated at 3.500 . I am going to try the H4831SC with the 208 A-MAX , 200SMK and 220SMK . I finally have a primer pocket uniforming tool and flash hole deburer comming . The groups with the two already tested were just over an inch at 200 yds (trigger pull ) . I most deffinately need a new trigger ! The stock one blows ! Pull is inconsistant ! Any one else out there with loads for the 300WM feel free to comment .
 
Re: 5R 300 win mag loads ?

I've had great luck with 75 grains of RL22 under a 180 grain Nosler Ballistic Tip, lit by a Remington 9 1/2M primer.

I haven't shot it past 300 yards yet, but it seems to hold together nicely at that range with no obvious vertical stringing. Groups have run around .75 MOA at 100, 200, and 300, and that's as good as I can shoot with this rifle.

YMMV...
