I just grabbed a .357 cartridge, loaded with 6.0 grains ("maximum load" according to Speer manuel...that's not really maximum) behind a Midway 158 gr LSWC and fired it in my 4 inch Python.....I'd swear I was shooting .38 Special. The Speer listed velocity for this load out of a 6 inch Python was 1034 ft per second....I can only imagine how slow it was out of my 4 inch. That is really pathetic loading data.
