RCBS Rockchucker usage

[jsl3170]

Fellas:

I am new to reloading and have the rockchucker setup at home. having trouble getting the case trimmer set up to go. any help?

intend to use the nosler guide since i have a bunch of partitions (375 H&H and 300 grainers). intend to load to about 2350 fps for hunting the local whitetails. will be using IMR 4350 and CCI 250 Magnum primers. I realize it is usually recommended to start new loads at 10% below max listings. will 10% yield that 200 fps less than what is shown as the 2550 loads?

Thanks!

Jeff

What kind of case trimmer do you have, and what problem are you having?

Using 4350 powder, and depending on barrel length, I would expect to see closer to 250 - 300 FPS reduction at 90% of max.

You will be running compressed charges by the time you reach max loads with that powder & bullet weight in the .375 H&H.
