454 Brass - Open Primer Pocket to LP

[44man]

Open the flash hole with a 3/32nd's inch bit. Use either the standard or magnum small pistol primer and you will be able to light any pistol powder you want. I did this with a batch of .454 Cassul brass I found mixed in with my .45 Colt brass I got from an indoor range.

I just trimmed them back to .45 Colt length and use them with my Anaconda and have had no problem with them. I do keep them segragated from standard .45 Colt cases w/ LPP pockets.

I would not suggest this because if one ever gets mixed up for a high pressure load you will be in trouble.
I have one box of cases with drilled flash holes just for rubber bullets fired by primers only. Those are never removed from their box.
Please do not open flash holes in .454 brass.

I am lifting this thread again since I acquired a tool to open the primer pockets on the .454 brass. I don't shoot much full power loads any more, and figured that a LP primer should be sufficient for my use. And it also makes switching between .45 Colt and .454 Casull a lot easier on the Dillon 1050. I just need to get some more .454 brass before doing any testing, I don't want to experiment with my original FA brass.

You can always cut down 460 brass to get a large primer pocket

That is of course a possibility, but I would prefer to use LP primers, and .454 Casull brass is cheaper and more readily available also.
