Never had an issue with any cylinder stoppage due to excessive bullet creep in my S&W J frame Airweights (all +P rated). However, after firing four 158 gr LSWCHP 38 Spl +P Rem FBI loadings, the fifth unfired round exhibited a little bullet creep. Even my 38 Spl +P 158 gr LSWC reloads (5.2 grs Unique) exhibit bullet creep from the unfired fifth round.
I never had a malfunction due to bullet creep but I was surprised to see some bullet pull even with Rem FBI factory loadings in my Airweight J frames. Needless to say, I used a heavy crimp (one full turn in my Lee FCD, as opposed to my usual 3/4 turn) on my latest 158 gr LSWC +P reloads, they now look like Buffalo Bore heavy crimps! Factory and reload 125 gr 38 Spl +P JHPs never exhibit any creep, they measure the same length before and after.
Pls share your experiences regarding bullet creep with 38 Spl +P 158 gr lead loadings in your Airweights.
