Hey friends, happy Monday.
I have a question here about handloading 357 magnum rounds with Berry's bullets. I have had great results handloading 38 specials with N340 powder and Precision Delta's .38 bullets. Now I want to move on to the big stuff, 357 magnum.
According to Vihtavuori's online data, the N340 powder can be used with Berry's 357 158 gr FP bullets. However, these are not cannelured, which at this point is important to me for proper crimp. The cannelured version, Berry's 357 158 gr FP TP, has a thick plate that might affect the load data. However, loading data specifically for this bullet is not available from Vihtavuori.
So my question is, can the starting data for these bullets be used interchangeably?
Thanks!
