Re: 300g berger hybrid oal issues
The vast majority of that ogive is secant with only a very small bit of tangent ogive right as the ogive transitions to the bearing surface.
I have heard that Redding is now making new seater plugs for the VLD's. Might not be a bad idea checking into that. I doubt even these new plugs are very near the tangent portion of the 300 Hybrid ogive, but they should contact nearer the bearing surface than a standard seater plug.
Another way to get consistent OAL is to use a micrometer seating die, if you haven't considered that yet. I picked up the micrometer portion for a 338 Lap Imp seater die I already had from Forster earlier this year and it was only about $35. You seat 'em all about 6-10 thou long and then go back, using the micrometer portion of the seating die now, and adjust the micrometer the necessary number of thousandths for each round to get the seating depth for each exact. Learned this from Shawn Carlock's video on reloading. Just a little extra $ and time for the peace of mind knowing that your OAL's are all exactly the same.
Edit: Use the same (label it) Davidson's (Carlock's recomendation) comparator for this operation to ensure that the process is as exact as possible.
