Fire formed load vs virgin load

I found a perfect load for .30-06
54 gr h4350
Nosler 180 ballistic tip
0.02 off lands
Low es
Small groups at 300
3x fired win brass

if I put this load in virgin brass, that is FL resized, with primer pocket cleaned up, what are the odds it's going to shoot good also?

Very good - I have shot new loaded brass into groups with reloaded fired brass (match grade rifles) and could not tell the difference.

Depends, is the FL sizes virgin brass the same brand??
If its a different brand or even the same brand but different lot/batch for that matter the case volume will be different & will have an affect.

Could even be slightly dangerous if your at max load or above!

Didn't look up the load.
If you're not near max and same lot of brass you should be fine. If different lot or especially diff brand, go back at least a grain and work back up.

You will never know until you run it in your rifle. I have had it make no difference and then again I have had it make a HUGE difference depending on the rifle. I had a 7mm Mag Rem. 700 that shot patterns not groups with virgin cases. Take the fired case and part size it (neck size) with a FL sizer die and same load would shoot bug holes.

Ok thanks everybody
Sounds like odds are good, but test to make sure

Be safe out there
Wash your hands
Don't pick your nose/rub eyes
It's the real deal

It's a funny thing, it can actually go both ways. As I've had it happen to me. I once owned a 300 rsaum, and with Nosler brass, that rifle, would shoot bugholes, with virgin brass, but I could never get it to shoot as well, with reloads. No matter what I did.
I guess it has to do with how close to the specs of your chamber, matches the specs of the manufactured brass. Again, I think it can go either way.
All the best to all. Be safe!

@7stw I wonder what the reason for this is. I have had the same thing happen to me with my 30/378 Wea mag. With resized cases from the same chamber my accuracy is MOA and with virgin brass it is slightly under MOA. I thought of trying small base dies to get the brass back to original spec but they are very hard to source. The concericity and other aspects that I could measure were good. The only measurement I would not repeat was the shoulder bump. It is much greater with virgin brass than it is with resized cases(.002-.003).Not sure if this could cause something.

Thst could be a variable as well, as the belted mags are headspace on the belt, not the shoulder. So the the factory set distance from the shoulder, can be as much as .040. Once its fired, the die will eventually control it, but not push it back to where it was before you fired it. And, the farther it is away, the more stretch you get above the belt area.
I never did figure out why the factory brass shot better, but, at that time, Big green, was putting out some lousy chambers, and if it was on the liberal side, you were effectively pushing back the shoulder every time you resize, which shortens case life, and I was having that issue as well. Just a few 20/20 thoughts!
Be safe!
