Bestboss - I shoot straight WW metal without leading to 2,200fps in my .458's. I'm using mostly Lyman's Moly lube lately, but have the same results with Lyman BP Gold and SPG. This shooting includes 420gr. Lyman and RCBS bulelts as well as 505gr. Lee, 525gr. RCBS and 560gr. Lyman moulds.

All the above are capable of shooting into 1" at 100 yards - no leading.

I size and lube using an RCBS lubemaster as well as a Lyman 450 lube sizer. The secret, if it can really be called one, is to run the bullets .001" to .002" larger than the groove diameter. If they are groove diameter or smaller, they'll lead the bore. I use a polished out .459" die. It sizes my bullets to .4595".

With the heavy bullets, jacketed bullet duplication loads are simple, fun and easy to load for. I especially like the Lee 505gr. bullet with gas check. It's an especially good shooting bullet, generaly cloverleafing the first 3 when driven at 2,000fps to 2,150fps. The only negative, is I don't like Lee mounds.
