I have bunch of FMJ .308 bullets almost identical to a few FMJ 30-06 bullets I have. Can I use them(.308) to reload 30-06? THANKS

I've seen 30-06 listed with 147 gr bullets
It depends. Almost isn't certain sure.
What are the bullet weights, shape, etc? What do you intend to use them for?
I've done it for years, straight from 7.62 nato ammo to .30 cal cases and the reverse. Never had a problem. All measured at .308 too, I know, I checked.
Weight/size data-Look at the table in my original post. Columns are shifted. Target shooting. If it goes bang and cycles ok I'll be happy. THANKS
I wasn't target shooting for group accuracy, I had a BAR, an M1 rifle, a Johnstone Automatic and a 1903 Springfield. I needed cheap bullets so I pulled bullets from our IVI 7.62 ball. I used them through thousands of rounds of .30 cal and had no problems with feed or practical accuracy.
The .30 cal bullet M2 ball is 150 grain flat base, the 7.62 bullet, M80 ball is a 147 grain boattail. They are pretty much the same length, but the cannelure is in slightly different location on each. Bullets like the Hornady 30 Cal .308 150 gr FMJ-BT 3037B al close to the M80 ball than M2 ball. Loaded to the cannelure in .30-06 OAL is on the short side. M2 bullets loaded to the cannelure in .7.62 may be too long.

Can you use the 148 gr BTFMJ from the 7.62 x 51 in the 30-06. Yes you can BUT you will not get the best accuracy out of the 30-06. 30-06 is best with a rate of twist of 1 in 10 while the 7.62x51 rate is 1 in 12. The difference is the bearing surface of the two different rounds. The longer bearing surface the better in the 30-06 being the standard 150 FMJ with flat base.
The Springfield 1903 rifle was initially designed to shoot the 220 grain round nose bullet that had been used in the Krag. After the Germans started making ammo with pointy bullets, US Ordnance hastily replaced caliber .30-03 with .30-06. They did not bother to change the twist rate. Many manufacturers still use 1:10 twist in .30-06 and while using 1:12 in the same model rifles chambered for.308. One reason the -06 is a better choice if you like heavy bullets.
What has been said is all true. The M80 bullet when seated to the cannelure in a 30-06 will have a shorter OAL, than the M2 bullet. 1:12 is better for lighter bullets than 1:10 but within 200 yards it probably doesn't matter. Faster twists usually are more versatile. In the AR-15 the 1:7 will shoot anything pretty well but the 1:12 shoots the M193 more accurately than the M855. The 30-06 holds more powder and can use heavier bullets (M1 Garands need to watch this). My take on any pulled military bullet is the weight variation. The M80's can be +/- 4 grains (made to cycle and go bang) so if you take the time to weight sort them, they work better. Most of the bulk 150 grain commercial FMJBT are better than any batch of pulled M2 or M80 due to their tighter tolerances and less handling. Just my experience with all of the above.

Norma used to sell a 220gn .308" RNSP bullet; known for its impressive performance, even on "Texas heart-shots". They seem to currently only list a 200gn job, though.
See Sierra for other options: .30 CALIBER/7.62MM 220 GR. RN Sierra Bullets
We don't seem to see those here either. I would have preferred them for loading Krag 30-40.
