Re: Starting load for 200gr WC\'s in a 7mm WSM?
I shoot 175SMKs, 67.3 H1000, Fed215GM in my 7wsm but would be interested in what you find best for the 200's. Mid 60's Retumbo is where I would start. I was getting decent groups with Retumbo, 180 Bergers and 175SMK, (68.5 gr) but H1000 did as well with single digit ES. The heavier bullets might bring the Retumbo in. I have a 9.5 twist so I don't think I'll attempt the 200's. Maybe next barrel. What twist are you running?
Another sweet combo for mine is 162Amax and 70gr H1000. Latest batch of Amaxes measured 80% +/- .001 Base-Ogive outta the box. All were within .004.
Hope it helps, keep us posted,
