I reload 38SA for 4 and 5'' barrels, 357 for 6 and 20" barrels, 9mm for 3.8, 4.25 and 5'' barrels and might eventually add 38spcl to the mix, so far only used in the 20" barrel. I was entertaining the idea of standardizing the projectile for all of these to one bullet weight and then developing loads I liked for each. I'm not a reloader of long or broad experience so I would like any feedback the community could offer on difficulties/pitfalls to this idea. Thanks all
