I think I posted this around here before someplace.  It gives you an idea what @JBMatt is talking about.  The holdover for a 300 BLK sub at 1000 yards is HUGE. 

 

So, who's bringing the balloons?

It's really cool to watch 220's through the scope when the sun is right.

Hell yeah, I don't use a scope on mine but when I lob them out there it can be cool as hell if the suns right. keep us posted on this

Have to admit being curious about... A subsonic 300 Blackout load; into what barrel? How purpose built is this gun for 300 Blackout to 1,000 yards? 

[JBMatt]

16" Ballistic Advantage, suppressed.  Nothing too fancy, but not junk, either.  Not ideal, but not impossible.

[Lane]

Thanks for the update. Being a NY resident; I can't even talk about suppressed.

What's the twist? You are hitting them point first? 

[JBMatt]

I think it's a 1:7 twist.  Fast enough that I think this idea would be possible.  I'm sure they'll be coming down point first, but I'm pretty positive they'll be coming in like a lawn dart! 

[DNP]

I was thinking you might have to lay the target flat on the ground to have a better chance of hitting it. What does the ballistics chart look like for this round?

[JBMatt]

Ha!  You're probably right.  That's why those balloons in the video were such a great idea.

My rough calculations show that I'll likely need 50 MILS of adjustment.  At that trajectory, the bullet hits the apex at around 145 ft or so.  That's a long ways up to come down accurately.  That's over twice as high as the same bullet apex's out of my 300 WM when shooting at a mile.  That's only about 65 ft.

Amazing and a great way to explain trajectory. 😁

I cold-bored that Win Mag Mile - you should be able to pull this off with the 300BLK at 1k yards...   I'm just sayin'...

@JBMatt, Todd bought a Savage bad-to-the-bone .338 Lapua bolt gun - he wants to hit the Mile BAD...   His Win Mag wouldn't do it (poor choice on projectile selection), so we'll be dealing with a .338 Lapua at Spring Shoot. 

Interested in an over-and-under on whether we hit before he does?...

You did what?  No way.  How come I've never heard you mention this before?

Hey, when you do something like that, you're a little proud of it.  It even shocked me...
