The 105 tends to shoot quite well; it seems to be a good bullet in the cartridges I've witnessed.

Thanks Guy's!

Is the reason for the difference in the max loads between wayno's and DrMike's data due to coal and or case volume? Noticed waynes case volume used was 59.97 vs Mikes at 57.04. Also, coal on Mikes was 3.10 vs 3.35 on waynes.

You are absolutely correct in your assessment. FWIW, the Berger Manual shows a COAL or 3.100 inches. Interestingly enough, they show a maxmum charge of 50.7 grains of MRP for ~Max Vel of 3152 fps from a 26 inch barrel.

NOT what you asked for but my load is

58 gr Magpro 90 gr AccuBond at 3440 fps and /6" groups from my 24" vanguard!

Yep, the COAL changed your case volume. I couldn't resist helping out since I just got my copy this week. Usually, I am the one asking for numbers. I am a little disappointed they still haven't added Alliant Power Pro powders to the quickload library.

QL doesn't take the Weatherby freebore into account. So an extra grain or two above recommended dose can be done.
