That’s similar to the .357 magnum load I tested this weekend out of my 3” S&W M60 Pro Series. 110gr Hornady XTP over 20 gr H110. I didn’t have a chrono, but plenty of giggle factor from the massive muzzle blast out of a J Frame.AndyC wrote: ↑Mon Jun 18, 2018 8:31 am Got my .300 Blk loads tested on Saturday. Interestingly, there was a guy next to me using 3 rifles with some very obnoxious muzzle-brakes that affected the recording of my own strings so I won't bother posting those screenshots, but the end results were these:
110gr Hornady V-max w/ 19.0gr H110 = avg 2,255 fps
125gr Sierra Pro-Hunter SP w/ 18.0gr H110 = avg 2,120 fps
