I agree as you are just behind the 300 Lapua which runs only 3055 with 86 grains of H 1000 in a 26" barrel. You are likely running less than 80 grains to get to 3000 fps in your custom 300 Win Mag. I believe Hornady could have done better with a design based on the 28 EXTREME or 7mm LRM which would hold just a bit more or a bit less powder than your custom. The longer neck would allow shorter bullets to be seated to the lands and still be seated with bearing surface ahead of the Neck/Shoulder junction. An adjustment in throat angle and freebore may be necessary as well. As you can see either design would fit in a Standard 3.6" Magnum/30-06 Length Magazine. I see that I did not open up the neck properly on the EXTREME design when I re-drew it but it would be just like the LRM neck.
