Does anybody have a good starting point for this load? Have a box of 210 VLD's on the way. I have a Remington Sendero pretty it has been bedded and a brake on it that's about it. I have IMR 7828ssc and H 4831sc. Thanks
With 7828ssc, we list a start load of 68.0 and a max of 71.4gr. For the H4831SC, start load is 66.5 with a max of 70.2. Hard to say what will be the best load until you try a few and see what the rifle likes. Someone else may be able to share personal results but I've never shot a 300WM personally so can't help you with too much detail.
I shoot the 215's with H1000. So not sure how helpful this will be. I started at 73 gr of H1000. My rifle shoots the 215 at 3000 fps in a 26" Brux. If I were you I would try this combo. Many others on here do for good reason. It just works.
Tried the H4831sc, but my rifle did not like them that well. I would go as BROZ suggested if you can get your hands on H1000. The only difference in his recipe and mine is that my rifle liked the 210 about .010 off the lands.
