I bought 155 gr. copper-plated semi-wadcutter bullets recently to use for .40 cal pistol (target shooting). The LYMAN's book covers only 150 gr type, suggesting 5.0gr of W-231 for accurate load; and they tested JHP bulets (not solid as I have).
Should I change my powder load and to wich side?
Or where can I find load data on 155 bullets?
Thanks.
