Gunner, I haven't but the heavy bullets will not stabilize in the 1:12 of the 375 Winchester. At least not for me. On the 38/55 they are very accurate. Drop Woody a note. He loads them in his 38/55. jorge
You need to try that again. My regular load in my 375BB is a 300gr cast FN and it’s very accurate.
The long range 38/55 users set up their rifles with 1:12” twist barrels and they stabilise even heavier 330gr pills at BP speeds.
