So this surprised me!

Is It Possible 350 Legend at 3,033 fps

Great video but using a 90 grain bullet with an extra long 20" barrel to hit 3000+ fps isn't exactly normal 350 Legend shooting.

Was hoping for more realistic hunting loads and barrel length.

I want someone to develop a good SBR load that beats the Barnes 110gr 300blk, that might convince me.

Don't discount those light bullets if they are good bullets.  When I tested the Hornady .357 125 gr. XTP in the .358 SOCOM, using AR-COMP powder in my 24 inch barrel, I achieved 2850 fps easily without pushing things past 36,000 psi.  Another powder likely would have given me higher velocities.  I did the same for lightweight .40 caliber XTPs in the .400 SOCOM.  In both calibers, I was honestly expecting the bullets to come apart in the air, and if not that, completely blow up if they hit anything substantial.
In drywall testing, two layers of drywall, 3.5 inches apart, and water jugs set up behind the drywall, not only did the XTPs make it through both layers of drywall, they completely disintegrated the first gallon jug of water and split the second jug of water.  The bullets did shed some lead and weight, but they did not blow completely up.  They did not group real well, but better than I expected, namely 3-4 inches for 5 shots at 100 yards.  Recoil, what recoil?  First time I shot them, if not for the water jug exploding I would have questioned if the bullet had left the barrel.
So while these small high speed bullets may seem silly, with the right bullets they do have a use.  Now if Midway would just bring those Hornady Critical Defense bullets, 110 gr. .357 spitzers, back on sale, I would really like to try some of them and see if they can flatten out the trajectory some and retain some of that velocity.  Those blunt low B.C. little lightweight XTPs shed velocity like a feather and do not shoot anywhere near as flat as one might suspect given their high muzzle velocity.

The big bore AR cartridges already bleed KE going down range due to the relatively poor BC of the bullets commonly used and that 90gr bullet makes that problem even worst with a G1 BC of ~.12.  It has lost half of its kinetic energy at ~120 yards.  No sure I see the point.

Because we are men and we do stuff like this for fun. I’d love to see what that would do to a yote.

That was some impressive damage but would the 90gr bullet be as impressive at 150 yards?

I'm going with the 118gr XD for now.

I might have missed it.  What is the muzzle velocity of the 118gr bullet?
