I'll answer for him - NO! Do not start at 27/28 gr. with 125 gr. bullets and work up, you will run pressures into dangerous range. The 27/28 gr. is max load no matter the bullet weight. The data is basically the same charges, even with different weights of bullets. I had very good results with 125 BTs on top of 22 gr. of Blue Dot. Very accurate, negligible recoil.
Seafire, if you care to dispute me on this, feel free, I'm running off of your data and what you have told me.
