Anyone have the load data for the New Barnes 300gr. Banded Solids in a 375H&H
Especially using RL15 and IMR 4064

This data is for the old style 300 grain X and solids. RL15 72.0 grains max for 2645 fps. IMR 4064 67.0 grains max for 2548 fps. These are also the two powders they recommend for this.
You might be able to go 1 or 2 grains higher with the banded solids, but there really isn't any need to.
Hope this helps.

Thanks for the info that will get me a good idea where to begin.I can reduce those Max. loads 10% and work up from there.

IMR-4064 From 52.3 grains to 68.7 grains
Remington 9-1/2M Primer

RL-15 From 56.8 grains to 72.0 grains
Remington 9-1/2M Primer

But I preferred:
H-4350 From 72.0 grains to 81.5 grains
Remington 9-1/2M Primer

Thanks for the Data
