Hey all,

Just wondering if anyone has put these factory rounds over a chrono? They have been my go to and seem to always shoot really consistently.
Think they are advertised at around 3240fps or so?
Just curious to see what anyone has come up with.

Cheers

I am guessing you have a 223? The speeds seems about right for a factory barrel, are you hoping they go faster?

Yes 223.
Hoping they go faster? Nah mate, only curious.

The speed sounds about right, you can get about 3350 fps out of them if you handload. If you are curious, drop around to my place and fire them over the chrono.

I have chronoed them before not sure of the number off the top of my head, but they are hot, they are well above were most people would say to start load development. In fact they are right on the upper limit.
