.470 NE cast

[Gareth flanged]

Hi

I have a lee ..470 mould which drops 400 grain lead bullets.
I can't find a load for my . 470NE. Everything seems to be 500gr. Can anyone suggest one or a place to look?

If its dropping a .470" bullet, then it wont work. Your going to need a .474"+ bullet.

As for a load... Thats going to be tough. Is it a double rifle? If so, you will probably run into regulation issues because you wont be able to push cast lead bullets fast enough.

Thanks for the input,

Yes, it's a double krieghoff, would a gas check help do you think?

Gas checking wont help if the diameter is off. A .470" bullet wont really work in a gun with a .474" barrel. Ideally you would want a .475" cast bullet for such a barrel.

Even if its the right size. Cast bullets dont like NE velocities. You would need to slow the bullet down quite a bit... Which will mess with regulation. That is also assuming the gun will even regulate with a 400gr bullet at any speed.

If you really want to use cast bullets. You might be able to get a 500gr gas checked bullet to work at a roughly 30% reduced velocity. Messing with double rifle loads is quite difficult and getting different loads to work is a matter of both luck and skill.

Thanks, that makes sense, I'll start with that in mind
