470 Reduced Practice Loads

[Huvius]

The first step, I’d suppose, is to source the correct bullets which in the 470 isn’t as easy as it is for a 450 but a 475 Linebaugh or 480 Ruger bullet should work just fine.
Try a standard charge of powder which regulates in your rifle with the 500gr bullet and as close to a 375gr bullet as you can and see what happens.

IMR3031 is very close to stranded cordite in pressure and burn rate. Has anyone tried to decipher the cordite load data for the lighter bullets and tried that spec in their double rifles? I would assume that the velocity would be so high they would cross horribly, but "I want to believe".

If there is a starting load we can deduce, I'd love to see how it reacts in our doubles. Heck, I'd hunt deer with my 470NE if I could toss a 300gr bullet at 1950fps with accuracy.

I was thinking about the same, kind of anyway. I’d like to have a starting load for CEB bullets that are typically a bit lighter. In this case the 460gr Raptor.
