Lee HB 405

[brad925]

My Lee mold throws the 405HB at about .462 to .463. My H&R B.C slugs at .457. how much can i size these down or should i size them down to?

[Larry Gibson]

I've pushe mine through .457, .454 and .451 sizers to PP them. If cast soft they swage down easly. I do very lightly spray them with Dillon case sizing lube first though. I also push them through the sizers base first to kep the bases square.

I casted these with straight WW's. If you run them through base first will that not deform the nose?

[Larry Gibson]

Just gives the sprue plate and nose a nice meplat. Notice I size them down in stages not sizing enough (lubing also) to deform the nose very much in any single sizing. A bullet with a slightly deformed nose will always be more accurate than one with an unsquare base.

If you are using a Lee or other push through sizer, do it as normal, nose first. Most others are pressed into a die base first requiring a nose punch.

Sounds to me like you have the Lee?

Lube them well and try one to see if the press and your arm like it.

I've got a 405 double Lee mold that throws them .457-4.58 I'll trade you.
