Just got back from a bunch of velocity testing at the range.

Thanks for that data sir.

I wonder how close my 18 in jp barrel will be running with 123 sst rounds compared to your data.

Those numbers are consistent with my string of 33 shots taken over a year's period in my 18" Bullberry barrel (Encore):

Count 33
Average 2475
SD 23
ES 91

The Lilja 318 profile barrel is 18.8"?

I get closer to 2500 avg in my BHW 18" 1:9... sorry no chrono shots...

The Lilja 318 profile barrel is 18.8"?

Sort of... Lilja includes the entire barrel extension in their length figures so to get the "ATF" length (i.e. measured from the bolt face) you have to subtract about .75".

My barrel is actually 17.6" on this one. I had some work done to it.

Shot side-by-side with another Lilja 318, they are within 20fps of each using the same loads.

Attached.

I measured like 20-30 shots and came up with 2530 from my Lilja 319 barrel.

2538fps is pretty fast for an 18". Nice.

How does it shoot? If posted elsewhere, post the link.

Anything I can provide to reference how well it shoots will be opinion and I know I was not doing my part as a shooter; still learning techniques for shooting from a tripod and ballhead. I've only shot for marginal 4" groupings, as the gun was built, sighted and put to work quickly. I can say that it has achieved vital kill shot placement out to 440 yards on whitetail and yotes.

The next opportunity I have to spend some time on paper, I will certainly post results. The lack of time to do so, is why I'm shooting factory ammo currently. I've been reading on this site for quite some time and found a few recipes for hand loads I would like to try.

I suspect my suppressor is skewing the velocity as well, as my 14.5 5.56 is running hot velocities on 77gr SMKs. Saker762.

I'll be sure to chrono a string without the suppressor as well.
