Tried #9 before like Longshot better but does not fill case. With Speer brass the primers don't seem like they fit as tight as other brass. Wondering if anyone else experienced this.
I agree Speer casings seem to fit primers tighter than others. I like Blue Dot, except it's dirty. It has an interesting sounding report too. A#9 meters better, but its so fine it makes a mess.
Sometime want to try Power Pistol. Have read that Longshot and Power Pistol are the most accurate for the 357Sig round. My trials were AA#7, AA#9 and Longshot so far.
I'd use Power Pistol but in thru Lyman and Lee codexes the velocity is lower than Blue Dot or A#9. I feel like I'd be wasting powder to load it in a 357 SIG. I use Power Pistol in 9mm and .45. I really want to get my hands on Ramshot Enforcer for 357 SIG.
