Thread: Anyone chrono a T3x in 6.6 Crd using Hornady 143 ELD-x

So the 2375 i got from the 16" a while back could well have been some "slow" factory rounds. I used to have a browning 6.5 prc, sold that and replaced it with a tikka 6.5 prc. Next to no difference in speed between them with the same load, the browning was 2" longer (26") so was always going to be faster but they were within 50fps with the same load.

Greetings @6.5 CRD,
The differences between the three barrel lengths is about what I would expect or a loss of around 20 to 25 fps per inch down to 18 to 20 inches and rather more below that. All are lower than you would hope for, even with factory ammo. You leave a lot of performance on the table with a 16 inch barrel. It seems the only way you get consistent ammo is handloading or sticking to the more expensive stuff.
