105"/11.5" Velocities

[BookHound]

I need to put the info in a meanful chart similar to what CarlosDJackal has done (which looks awesome!).

Rough data though is:

16" Bushy barrel; 55-grain Prvi = 3188 average
11.5" Sabre barrel; 55-grain Prvi = 2939 average
11.5" Sabre barrel; M855 = 2844 average
10" HK416 barrel; M855 = 2686 average

We were mostly doing sound metering with various suppressors and mostly with 7.62 cans. We had some other ammo but needed to focus on just the Prvi and IMI M855 as far as the 5.56 testing was concerned. I'll put together some more complete data in the next few days.

Thanks for the great info! I'm surprised how fast the Prvi is out of the 11.5" Sabre. Are the Sabre barrels 1/7 ? The HK?

[BookHound]

The Prvi shocked us too. Fast stuff there. Yes, the Sabre is 1:7. Ya know, I don't remember what the twist is on the 416. The 16" Bushy is a 1:9.

I didn't know that Sabre made an 11.5" barrel. Do they make a complete upper in 11.5"?
