600 yards with a suppressed SBR

[Fireman1291]

It's nice to know that its possible. The delay in impact was neat. And with the low BC of that round I'm surprised the wind didn't carry it further off track. I sent one spotting round center at the halfway point up the berm and then used Kentucky Windage to find the hold for the wind.

The target was an steel 8" gong at the lower left of the berm at 575 yards. I hit it more than once freestanding using my BUIS as my eotech died.

A neat learning experience.

I did this on a smaller scale with my 22lr short upper. At 100 and 200 yards. Very nice to shoot the little suppressed round like that and hear the ting at 200.

Try 300 and 400 yards with subsonic 40grn 22 Lr
10 ft hold over at 300 and 20 ft at 400
It makes shooting other subsonic rifle rounds easier at those distances.

Watching the flag next to you, it sure does seem like a lot of wind for 575y 556 free standing with an EOTech. If that flag was 5mph, that's 20" or so in wind. Were you holding 20" off target?

I was holding 4' right and 5' high to hit it down at the bottom left of the berm.

Hmmm, using the numbers from my 16" gun (2850fps and 69gr ammo) you should have needed 7' of vertical hold... You sure you were holding right? That wind sure looks like it's coming from 9 oclock on the flag next to you...? The minimum wind needed for 48" hold right would be 12mph from 3 oclock (opposite the flag next to the shooter), so.... Not saying you weren't getting hits, but um, that sure doesn't seem to be adding up, considering the definite differences in velocity between your SBR and my numbers.

In fact, if I were to guess 2200fps on your SBR, I would say you would have needed around 13.f FEET of hold over, and taking my 69gr BC, it seems you would have had a bullet that was no longer supersonic at 535y.

I mean, you're saying your suppressed SBR has less hold and is better in wind than my 16" guns according to your hold estimates. That's just strange, you know? I look at me having to pay attention to a lot of factors to determine 7-10mph winds with a kestrel and a scoped gun to get good called hits on a 10" plate when prone...

It may have been a 7' hold. I never sized up the berm up close as my buddies walked the targets out as I had to stay with my NFA stuff on the line. All I know is I was getting 50% hits lol.

That's 7' for my gun. More like 10-13' for yours. Plus you sure it wasn't a 6' left hold, that would make sense considering the flag in the video. I'm not you know, like calling you out or anything, it's just your description doesn't at all match what I'm seeing.

You also sure it was an 8" steel? .... 16" to 20" would make a lot more sense

I know you're not. Yeah we all were wondering why it needed a right hold. All the flags indicated a wind form the left. The 600 yard flag would move back and forth while the others wouldn't. It must have been a turbulent crosswind that varied constantly and the wind indicators couldn't keep up with the change fast enough. We had a VERY large thunderstorm moving in from behind us that changed direction before rain fell so the wind was all wacky that day. Even benchrest shooters down the line were bitching about it. I just ran 2-3 spotting rounds off camera to find the hold and I was dialed in. It was fun.

Great Video!

I like the Manatee Range.

I wish I had a rifle that could reach out to the 1000yd targets. I was hitting the 500yd gongs with a Savage Bolt 308. Like 4 hits out of 20rds. Yeah I suck!

I got to Manatee fairly often, I'd love to see standing 565yd hits with that setup.

Intentional accuracy at 600 yds on an 8" target is better than minute of angle accuracy. Nice shooting. Doing it outta a 10-1/2 inch barreled anything, is admirable.

Carry on.

I think you might be bad at math.

[tsands974]

WTF is intentional accuracy? Not criticizing you, just never heard of it...

Hmmm... minute of angle is what, 1" at 100 yds.. 2" at 200... and so on....

Oh wait, I guess now that you point that out... You seem to have handed me my head...

My bad. Thanks.

Heh... now you can't say that.

A master of the wiseguy one liners, RO I knew, used the term to identify shooting with repeatable in hits on target, as opposed to the blind squirrel finds the acorn random hits.
