Reloading question regarding .430 diameter bullets

[Top Drawer]

Please could someone help with this question?
Is it okay to use .430 diameter jacketed hollow point bullets when reloading for a Super Blackhawk?
It looks like most bullets are .429 diameter. I have these new .430 diameter bullets and would like to use them if possible.
Any help would be greatly appreciated.

Load them

You could slug your barrel first but really not necessary. Standard reloading procedure, start with published starting load and work up. By published load I mean powder company or bullet company source not something that "Billybob" put on the Internet or recommended to you at the Range one afternoon.

No problems with jacketed 44 magnum bullets .429 or .430. Sometimes it just depends on who is doing the measuring.
Try to find load data for your specific bullet if you can.

Like the others have said, use them. You won't notice any difference. Some manufacturers spec their bullets at .429, and some at .430. It's all good.

And sometimes it's the same bullet!

Do you know what the groove diameter of the barrel measures? Do you know the diameter of the cylinder throats of your gun?
