The factory can sell you the #4 shot bushing.

Gamaliel's Shooters Supply has the entire range of Hornady powder bushings @ $4.95 each. Hornady uses each bushing's internal diameter as it's part number. Here is a list of common PW powder bushing sizes. The bushings you pick to buy will depend on the density of the powder you intend to use in your loads:
<center>C ---- 0.3220"<br>C1 ---- 0.3295"<br>D ---- 0.3325"<br>D1 ---- 0.3415"<br>E ---- 0.3645"<br>E1 ---- 0.3670"<br>E2 -----0.3785"<br>F ----- 0.3800"<br>F1 ---- 0.3850"<br>F2 ---- 0.3950"<br>G ----- 0.4125"<br>G1 ---- 0.4155"<br>H ----- 0.4290"<br>I ----- 0.4365"<br>J ----- 0.4450"<br>J1 ---- 0.4515"<br>K ----- 0.4545"<br>L ------ 0.4645"<br>M ----- 0.4775"<br>N ----- 0.4925"<br>O ----- 0.4955"<br>P ----- 0.5300"<br></center>

You don't need to have a bushing in every increment. I routinely reduce the capacity of a too-large bushing by a ½ grain or more with a piece of aluminum HVAC tape. Once I have a bushing fine tuned for a load formula I don't change it again unless a routine check of a new batch number reveals that the powder manufacturer has changed the density of the powder by more than that.
