Re: 210 Berger's in .300 Win. Mag
another vote for H-1000 and the 210. Johnboy and i use the same load, except seating depth. I use 76gr H1000 210VLD 20thou jammed CCI-BR2 primer. That primer has shot best in all of my rifles to date. Plus it's stronger and takes more pressure. Start 72grs unless your using hard brass like winchester and tough primers like cci. Should be fine starting at 74, but what the heck, load one at 72 and one at 73 to be safeR.
"Out of range" is a theoretical concept as far as I'm concerned. Send it!
