Why Yes, Yes I do ...LOL .
25x45 Cal. Does Great, going over 6 years now, and 2nd barrel with this Cal. it anchors them, it accurate, and it not to brutal .
I chrony'ed my load last thursday on the garmin @ 101 deg out, and in that heat is about as fast as it gets, primers were really flat . ( 16 inch Barrel ) The Vel. FPS. with 75 grn. was doing 2838 . The 87 grn, TNT's are doing nice @ 2700 . my powder choice is A-2230 / 'aka' Ramshot X-terminator . using in the area of 27 grn. of powder burn suppresses nice at night also .
Not that the 75's are subpar, they do the job . But the 87's really anchor them 'hard', there is a very noticeable visual impact difference over the 75's .
I get 3 good loads on the Brass then start noticing some primer pockets getting loose. but Brass work neck-up is easy fast and new .223 brass everywhere and reasonable priced.
Main reason I really like the Cal. is I get good Vel. with keeping shorter length with using Suppressor mounted 100% of the time . playing with .223 brass 6mm x45 is still the king, it's efficient but you Really need a Long Barrel to capitolize on the Vel. with 6mm and 223 case.
