ejumicate me... fireballs.

Not always for sure. This is taken with an outdated android phone. Hah! So it's not really video gear. I would say that it caught most of the flashes though. I think being such low light, that may have helped. It was basically completely random. I always thought it was as the barrel heated, but it doesn't seem to be the case.

Might be better than what I've tried to use. I can remember wanting to get footage of a specific flash hider, and the video wouldn't capture what I was seeing with my eyes.

What I got from OP:

10.5 inch barrel + 55 grain projectile (gonna go out on limb and assume .223/556)= Fireball

An over the counter 223/556 loading will not completely burn in a 10.5 inch barrel. If it did, a 10.5 inch barrel would have the same (probably higher) muzzle velocity of a 20 inch barrel. We know a 223/556 10.5 does not perform that way.

If the fireballs were on a 16 or 20 inch, I would agree that there is some MD voodoo going on or there is an ignition problem.

I was shooting 62gr ZQ1 FMJ out off my 18hbar with a non threaded barrel why such a fire ball on mine then?

Hey futurerider,

I Still >think< the design of .223/5.56 round was with a FH in place.... Yes/No? And from the sounds of it, yours doesn't have a FH screwed on...

I can not watch your video here from work...

Peace Jeff

There is no fh on mine at all.

Now that I think about it, I see the same variability on flash out of pistols in low light too.

[futurerider103]

I haven't noticed this out of any at my other rifles and I shoot .308, .270, 7.62x39, 30-06, and of course .22

I notice it with several of my bolt guns. I typically am shooting them at dawn or dusk (Deer hunting) and will notice it with the same lot of ammo having different volume of fireballs (Without a flashhider to have the carbon deposits on). I would think the sparkles would be the carbon flakes braking off, while the fireball would be build up of gases or oxygen. I typically notice it happens in sequential firing schedule and usually around round 4 or 5 (WAG) as I have never actually counted and written it down, but it seems that it was usually 3-5 rounds in between the larger flashes. I too notice it with handguns as well.

[futurerider103]

I wonder if this is cause by the heat causing the barrel to expand a bit allowing more oxygen into the equation to burn
