Nosler 220gr RN #30181 with 300aac

[SAWMAN]

I am always willing to learn but I cannot figure how this could have anything to do with ANY powder.
Bullet destabilization is a product of forward velocity,rotational velocity,vs bullet length (and possibly condition of barrel).
Anything else . . . please inform me. --- SAWMAN

I agree but I got nothing to lose trying something else.
Another picture that won't resize for me is of a 55gr Nosler Ballistic Tip Varmint fired from a 1:12" .223 that key holed religiously at about 1100fps muzzle velocity but did just fine at regular velocities around 2800fps.
I tried to get the velocity up higher in the 300aac but ran out of case capacity at 1242fps and it still key holed.

As I stated earlier. That grain bullet is to heavy. Drop back to a 165 or 168 and the problem is solved. The chance of you holding a hand grenade instead of a rifle gets more probable the more powder you add just to shoot a 220gr bullet. I wouldn't think that'd be worth it.

Actually I have since done just that.
I cast and powder coated some 166gr RN and got them a little over 1500fps.
Also have some 150gr RN jacketed at 1870fps.

Installed another resizer, it also has a mind of it's own.
Anyway, 50 yards and 100 yards.
5 shots each.

I can’t either, but at this point anything is worth a try. At least he has the powder on hand to give it a go.

The 300 blackout is designed to shoot 220gr bullets. 110gr- 225gr are well within its capabilities. That bullet was designed for the 300 blackout, so the OP is not doing anything dangerous or wrong.

Benny, did you not KNOW that a bullet that long,with that much weight forward,coming out of a 1:10 twist bbl at 930fps would not stabilize ??
It's lucky that the bullet did not do a U turn and come back to hit you between the eyes.
The above figures are about the greatest combo for bullet unstability that I have hear'ed tell about since Moby Dick was a guppy.
Look around the web and find that bullet stabilization formula. Several inputs later you will come up with a number that tells the "rest of the story".
After the bullet stability thing has been mastered,check over your barrel closely. If the bbl is flawed it could only show up when you get down close to the super vs sub vels but shoot the hot'ish supers just fine.
The bullet weight (actually length),forward velocity,twist rate,formula will get you goin' in the right direction. --- SAWMAN
