I received a shooting chrony "beta" model for my birthday and took it to the range today.
Firstly, what fun! It'll be nice to actually be able to tell what I'm doing with my reloads instead of the ole' "yep, that kicked pretty hard, must be fast" Anyway, here are todays results (all velocities are average of 10)
1. Slavia 620 --- 7.3 grain.177 caliber pellets --- 649fps
2. Rem. 550I 22" --- 40gr Rem. Golden Bullet .22lr -- 1152fps
3. Ruger SS 5.5" --- 40gr CCI MAXIMAG +V .22wmr --- 1546fps !!!!
4. Ruger Vaq. 5.5" --- 240gr Win. USA JSP .44 mag --- 1253fps
5. Ruger Vaq. 7.5" --- 240gr Win. USA JSP .44 mag --- 1366fps
6. Marlin 1894S 20" --- 240gr Win. USA JSP .44 mag --- 1696fps
The most surprising thing was the .22 mag, I wish I'd had some non +V to check it against, I'd always heard the .22 mag let you get .22lr-in-a-rifle performance out of a handgun, but this stuff blew the golden bullet away. Maybe a stinger or other superspeedy would narrow the gap. Or maybe I have a particularly slow Rem. 550.
I it was also neat to see the rule of thumb about 50fps per inch played out between the 5.5 and 7.5 vaquero ( A guy at the range saw my vaqueros and carbine and invited me to come to the cowboy shoot next Sunday)
The numbers for the Win USA are pretty close to factory specs so I think I'm getting good numbers. I think I'm going to get a couple level bubbles and glue them into the inside of the chrony case to make sure I get a good setup. Anyway, lots of fun, just thought I'd pass some of it along.
