308 165gr bullets speed

[bullhead]

Am going to try 165 Speer Hot Core and 165 Accubond. Powders I have are RL15, imr4064,imr4350. In looking at Speer and Nosler books it seems out of a 22" barrel top speed is about 2650 fps. Is this what you guys read? Anybody else get more with other powders? Thanks

57 grains of IMR 4350 with a 165 grain bullet is my go-to load for the 06.

I'm getting 2850-2900 out of a 24" bbl. You should be able to hit 2800 easily.

2,900'/sec with 165 grain Barnes TTSXBT out of a Sako .308 Finnlight carbine with 20 1/4" tight match grade barrel using by the book hair under max load with AA2520 the Camp Perry powder made for the 308. Very accurate. sub MOA. 1/11 twist.

On principal I drop the load down to 2.850'/sec.

My friend has a Tika in 308 with 22" barrel. Best max velocity he can get with same powder is 2,775'/sec with longer barrel.

With my Belgium Browning 30-06 the best I can get out of my 22 inch barrel with 4064 is 2,750'/sec

308 win I get 2750-2775 fps with Varget and H4895

 

[MTLabrador]

2700-2750 with Varget out of a 22” barrel depending on the bullet for me.

Similar to the two posts above I get around 2750 with 165’s out of a 22” Lilja with Varget.

What is a "tight, match grade" barrel?

I know of different manufacturers offering "select match" and other variations thereof.

All match grade means is that the bore is at a consistent tolerance.
Such as air gauging down the length of the barrel to be within 0.0005" for the length.

Not that the bore is on the tight side of tolerance.

You may want to check your chrono against another.
If you're "a hair under book max" , and over book velocity with a 4" shorter barrel, something is not right.
