375 ruger brass

[steve71]

This may be a stupid question. I have no experience forming brass. I have heard that 300 PRC brass could be put through a 375 Ruger resizing die to form 375 brass. Is this an option?

Thread 'Resizing 300 PRC brass to 375 Ruger'

Nov 16, 2024

Any thoughts or experience with resizing brass to a larger caliber within the cartridge family?

I have read where resizing 300 PRC to 375 Ruger is doable. It seems a two step process is suggested, first upsizing to 338 and then to 375.

With 375 Ruger brass being scarce, thought this might be an option for folks needing brass.

The outfitter I recently hunted with in Montana has a large amount of once fired 300 PRC brass (approximately 50 boxes) and will sell any or all for 50 cents per case, plus shipping.

I haven’t tried resizing 300 PRC to 375 Ruger yet, but as I understand the process, take your 375 Ruger resizing die and change out the expander with one for a 338 die. I have also read that people suggest annealing the brass before resizing. Once all the brass has been resized to 338, replace the expander to 375 and repeat.
