I certainly don't know, but would have thought lighter would be better on recoil, but it appears like most things it feels different to different folks and different guns too.
I am shooting a 5" which I like, but need to work up loads, and really appreciate all the input. I may try some 180s and 155s and see how they feel to me in this gun - I already committed to a bunch of Solo 1000, based on a lot of reading here on experience with it, to start my loads with.
Thanks.
