WyoStillhunter, I can totally relate.
Out of idle curiosity, I developed a load using a caster friend's 195-gr RNL bullet a few years back, thinking it might be fun to keep in the gun when wandering up Bear Canyon behind the house. (We only have smallish black bears here in NM, but I sometimes like to build .38 Special loadings that will perforate one if necessary. One of my favorite hiking guns is a 3" J-frame.)
The bullet up top; the other is Skip's 160-gr WC - also awesome:
I wound up using some old-time (hotter-than-SAAMI spec) data using 2400 (having tried a few other powders - Blue Dot, Unique, Power Pistol and BE - and gotten unsatisfactory results). I did not work all the way up to the maximum powder weight listed, as I found good results a bit below that. Here are some results from various guns (5950' above sea level, 60% humidity, 74°F):
Model 36 1 7/8" barrel: M 844.2/ES 35.83/SD 12.72
Det. Spl. 2 1/8" barrel: M 871.2/ES 28.29/SD13.49
Model 36-1 3" barrel: M 941.0/ES 32.50/SD 15.79
Model 15 4" barrel: M 973.2/ES 16.65/SD 6.32
Model 14-3 6" barrel: M 1030/ES 22.02/SD 9.53
I noted a couple of things of interest. The rounds all grouped at around 1" to 1.5" at 30 feet (the target guns showed much better potential than the belly guns). A great deal of 2400 did not burn and scattered all over the place. This was most evident with the snub Chiefs Special, but was somewhat evident at the bench with every gun
except (for some reason) the Detective Special. When I went to retrieve my chronograph (ten feet out), I found that there were flakes of 2400 liberally sprinkled all over it - I'd not seen this before. Interestingly, this loading gives me better performance than the same bullet in a .357 Magnum case over a supposedly max magnum loading of Power Pistol.
I'll not publish the data here (a little less than Bryan's loading), but I'd be happy to tell you about it if you want to email. cheers, erich
