I just ran some velocity comparisons between a 14.5-inch barrel and a 20-inch barrel on AR platforms.
I used an Oehler 35P chronograph with a 4-foot spacing.
Each test included 10-rounds fired.
Following are the results:
M193, 55-grain ball (Lake City)
14.5” Average Velocity = 2,948 fps
Based on your experiences, what are the performance differences between Remington .223 and 5.56mm? I already know that you can safely fire .223 ammo out of a 5.56 rifle (but I heard with degraded accuracy) but shouldn't fire 5.56 ammo out of a a .223 rifle.
Would you recommend I get an AR-15...
