| Anyone have comparison to UMC 223 and XM193 5.56 out of a 20"? |

Federal bulkpak 223 or XM193
Which is it? The 100 round value packs are 223 ammo and will be around 3000 FPS out of a 20" barrel. You could probably run some google searches and find some more info. I have not seen any recent chrono data for it. Any chrono data on the box? If it says 3240 FPS, what it doesn't say is that was from a 24" test barrel. Now if it is XM193, which is 5.56 ammo, there is chrono data all over. You just have to look for it. But it will be around 3250 FPS out of a 20" barrel. |

You boys send me 100 rounds of each load you want tested. I'll take it to the range, chrono it in 16 and 20", and post a range report here. I'll give mean, std. deviation, and spread. Deal? Too cheap to shoot you some. 
It is good stuff though isn't it? I've never had any malfunctions out of it, all rounds looked good to fire. I've probably used 300 to 400 rounds. It smells like cat piss though. |
