300 win and 215 bergers load development

[Joefrazell]

Your guys are making me want to bump up my powder with h4831

Just remember with 210 primers short cut powder for proper ignition.
We've had great results.

Looks like h4831sc gets to fill my cases. Just loaded up 4 rnds of h1000 with the 215's at 73.5, 74, 74.5, 75, 75.5, 76 and 76.5. They were all around moa at 100 yrds.

With this new lot of H1000, I ended up at 76.5 gr with the 215 Berger. Velocity was at 3016. Couldn't believe there could be 100 FPS between lots of H1000 previous lot I was at 75.5 gr. Well, long story short, I'll buy H1000 in an 8 pound jug and do a quick load work up to get on my velocity node and all will be good.

Used to run H4831 in a different 300 win mag a couple years back. My load for that gun was:

72.5 gr H4831SC
Winchester brass
Fed 215
2.910" BTO .005" off lands
3030 FPS avg.
ES 5
SD 10

Sold that gun to a guy at work who wants to get into hunting and shooting.

I was running 215 Bergers at 2860 with H1000. Couldn't wring another foot out of it. Went to Re-26 and got up to 3125 with a 26 inch bbl but the bolt got sticky so I backed off to 2,970fps with dime size groups. I'm a big H1000 fan but that extra 110 FPS with no pressure signs and tiny groups made me a believer
