I think you'll find as I have that a well lubed ,cast bullet sized .001 over bore size tends to be consistently more accurate than a bore diam. cast bullet except at very low velocity.
Ive consistently seen better accuracy in my 458 win and 450 marlin with .001 over bore diam. cast gas check bullets

btw I found this bullet to be especially accurate in my marlin 45/70 over 45 grains oF IMR 4198

If you don't mind my asking how long ago was that mould purchased?

.001 to .002 over bore diameter is my usual starting point for cast bullets so you will be fine. Of course, each barrel is different and the barrel will tell you what it likes best.

OK thank you all .I have all ways found the .458 cast in local shops. Never .459 ,I guess it will pick up pressure and give it a little more punch

Thanks, I have a few from that period. Those were cut by Mr. Melander before he left this world.
