Can't remember the charge weight but it was the max in the book using IMR 3031 and a 165g NBT out of my 77 International's 18.5" bbl. got me 2675 fps so you should have no trouble busting 2700 fps outo f a 20" bbl.

Does anyone know from first hand experience if a good (but still safe) handload from a .308 Winchester with 165 grain bullets fired from a 20" barrel can break 2700 fps?
Nosler also has a 165 grain Accubond factory load that is rated at 2800 fps. Anyone know what it would do from a 20" barrel? I have used Federal factory 165 Trophy Bonded P308TT4, They chroned 2840fps from my 22" stainless Ruger.

I get over 2900 FPS with Hornady 165 Light Magnums. I think you'll get close to that velocity with a 20" barrel. .308 WIn does not require a long barrel to achieve max velocity. BTW, I get better than 2900 FPS with 150 grain Core-Lokts. Good Hunting, R

Rem. 700, 20" Tactical
Sierra 165 HPBT Gameking
Federal 210 Primers
45.5 gr. RL 15
R-P Brass, 3 Times Loaded
5 shot string, 2686 fps avg. 28 fps extream spread.
Shot sligthly over 1/2" in 10-15 mph guhsting winds.
I started at 44 gr. and worked up in .5 gr increments. I averaged about a 20fps gain in velocity per .5 grain increment.
All groups shot less than an inch at 100 yards.
As always, work up with caution.

GB Good info, thx. Especially like the 20 fps gain for each .5. Dober

I guess my barrels are slow. Sure could be the case, barrels are like people (IE they're not all the same, some are fast, some slow and some just right). I'd not worry tons though in years gone past I did. I find top end, back off 50-100 and want the best accuracy I find get. Shoot straight Dober

Oh yeah, I don't run them hard at all for my purposes. I have a few real accurate 2550 fps loads that suit me fine.
