450 Bushmaster ?

The Gould bullet is great but it's .458 not .452. When you punch a 45 caliber hole in something expansion is unnecessary.

Hopefully your Ruger does not have a gain twist as my AR did. Cast were NG in it.

And I live in a state that requires expanding bullets to hunt deer.

Hmm, according to the Berger bullet stability calculator, the 405 grain Lee 45-70 bullet should stabilize in my 1:24 CVA barrel. Of course it will need to be sized, but it's plain based...this should be interesting. Shows stability even down to subsonic velocities too.

Will have to pick up that mold.

I had talk to my CO on cast boolits and he said they are ok for use in the rifle for deer hunting in this state of Iowa.I live in the same state as you . Hope this will help.No full jacket bullets.

I don't see any state, commonwealth or province doubting a LEAD projectile was anything but expandable.

(Regardless of what WE KNOW.)

I have a Ruger ranch and I shoot a Lee 255fn over 11.5 grn of unique is a real nice shooter with no recoil, however it won’t cycle my PSA 18” 450 AR

There are endless fun light loads to try for sure! Part of the appeal of this round for cast shooters.

9grn of red dot with the 255 Lee is nice,
16 gr of unique under the Lee 300grn was accurate but way low to the sights
