Loading 375 solids for first time..any tips?

[Basser2x]

I’m loading up some Barnes 300g banded solids for the first time for my 375HH.

Maybe I’ll save myself some time by asking for help here.

Do you have any tips? I’m curious if I need to change anything from the 75g load of Big Game I’m using for 300g Barnes TSX?

I’m hoping I won’t need to change the load or even the seating die (assuming the ogive will provide the correct OAL)

Thanks for your help!

As with any reloading, if you change any component back the load off and work up to your other load. My current loads are 1.5 grains apart solid and expanding. Shoot to the same poi.

What he said…

My .375 soft and solid loads 1.0gr apart

The Barnes load data is online and 75 grains is well below the max load published by Barnes

Don’t just swap them 1:1.

Barnes data shows a shorter OAL for the 300 gr Banded Solid 3.545" versus the TSX 3.570". Your 75 gr Big Game is in the ballpark for the TSX, but the solid’s bands change bearing surface and pressure curve a bit, so start lower and work up carefully while watching primers cases.

Seating die the ogive isn’t identical, so measure the actual loaded OAL and confirm it chambers cleanly. Don’t assume the same setting will give you the right length or proper neck tension.

Load a few test rounds, chronograph if you can, and verify point of impact. Plenty of guys get them close enough for practical use, but treat it as a new load development, not a drop in.

I my wifes 375 using 4350 the Aframe is 75 gr and the CEB solid is 73.2 for the same POI.

i mine it is 75 softs and 73 for solids.

Start at least 2 gr below and work up.
