38 Spl 148 gr swaged DEWC and HP38/231

[38SPL HV]

Using Lyman cast data, I've loaded up some 38 Spl 148 gr swaged DEWC (Magnus) with 3.5 grs with HP38...for paper punching fun. I used 3.0 grs in the past, but it was a bit on the light side but still accurate.

Any experience or pet loads with this bullet and HP38/231 is greatly appreciated.

I load 3.4gr W231 under a 148gr DEWC and it's one of my favorite loads. When loading a 148gr HBWC I drop the charge to 3.2gr.

My 66 likes 3.6.

I've tried 3.4 and 3.6 and haven't noticed any difference in accuracy.

I used to load the Hornady 38 148gr HBWC over 3.2 of WW231 for use in my K38. I was very happy with the accuracy.

I'm sticking with the 138 BNWC's in that gun. -S2
