I thought about adding to one of the existing Sport Pistol threads, but some where either too old, or went in a different direction.
I just picked up a lb of Sport Pistol yesterday along with a lb of VV N320 to do some head-to-head comparisons on some .40 S&W competition loads that will make Major Power Factor.
I am loading for a 2011 gun, so these will be long COAL loads (1.180").
I plan on starting out with my normal 180 gr. lead-coated bullets (I have Black Bullets International (BBI), Blue Bullets and Eggleston in house), but I may also want to check some 200 gr versions as well (BBI).
The loads I have worked up so far use WST at 4.5 gr., and I am getting a power factor of about 167, so I am probably going to bump up the WST load to 4.6 gr. to give myself a bit of a safety factor.
There is lots of data out there for N320 at 1.180" between 4.6 gr. and 5.1, I will start low and work up (of course) to safely make Major Power Factor.
Not as much data for Sport Pistol, but it looks like I should find something in that 4.6 - 4.8 gr. range with 180 gr. bullets at 1.180". Once again, I will start low and work up.
So, after all of that preamble...
Has anyone around here worked up any long COAL loads for .40 S&W with Sport Pistol? All of the published Alliant data uses a shorter COAL, so while that is worthwhile data, is going to take some extrapolating to the longer COAL.
