I finally have some Longshot data for the 9x25 Dillon. I started @ 11.5gr for a 90gr XTP, since 10.0gr is Hodgdon's listed max for a .357sig 115gr JHP. I have to admit I think it was a little aggressive for a starting point, but I haven't had any pressure signs yet.
Here's what I have so far:
Sea Level, 88* F
6.02" LWD Barrel
Wolff 22# Spring
9x25 Dillon Die sized Starline Brass
11.5gr Longshot/ CCI300
12.0gr Longshot/ CCI300
12.5gr Longshot/ CCI300
I am really happy with Longshot so far. With an average of 1920, and an ES of 18, who could complain? These loads are LOUD! The range I go to is outdoors, and the office is about 50yds away. The girl came out of the office to tell me to stop shooting a Rifle on the Pistol range, but got really confused when all she saw was me and my G20L.
I also loaded up the Blue Dot loads for 90gr XTP's that "Gun-adian" posted earlier this year. I worked up from 13.5gr to 15.0gr (indoors) before I had my chrony, with no pressure signs. This time I started @ 14.5gr and worked up to 15.5gr. I'm a little disapointed with my results compared to Gun-adian's, but I'm not giving up on Blue Dot. I think I'll try WLP's, and I may experiment with the OAL. The muzzle flash alone is enough to keep me coming back. Anything above 14.5gr indoors produces the biggest fireball that I have personally seen out of a handgun.
