Thank you MickinColo,
This will be very helpful.
Wasnt sure whether to believe the Hogdon data, they have 51gr @ 3054 fps from 24" barrel. Im going to have to further reduce my OAL to 2.75" so that I can give the bonded bullet a jump. My rifle will only accept this bullet loaded to max 2.79 touching the lands. I have loaded a ladder test from 48gr to 51 gr. Looks like a may have to start lower due the my short seating.
