This will be my first batch of reloads. I will be starting with 4.9 gn of VV N-320 and CCI LPP. I bought some Nosler sporting pistol bullets 230 gn fmj part# 44964. I ordered online and thought they were round nose, but turns out they are flat nose. The bullet length is .625 in. My Lee manual states min. COL for 230 gn fmj as 1.26. What COL should I use for these flat nose bullets. Thanks for any help. Don't want to blow my face off on my first set of loads, or at any time for that matter.
