Some are shooting the 308 really hot because they cant jump up in caliber and still compete in FTR class which is only open to .223 and 308. I run my 308 on a nesika action with a 26 inch barrel pretty hard with the 168s, but not as hard as some are running the 175 and heavier bullets. Funny thing about both my 308s they really like to run hot. But with the price of lapua brass I like to get more than a couple of loadings. I settled in around 2730 and my brass seems to be lasting pretty well and accuracy is great to 800. I think my pressure is probably in the 62K PSI range and my primers are flattening pretty good.
I admit that I know just enough to be dangerous.....but dangerous at ever extending distances.
I have run 175gr Molyed Bergers to 2700fps out of an 26" Obermeyer barrel ,this is a hot load Lapua brass only lasted about 5 reloads and thats saying ALOT for the pressures. I think my load was around 46grs of Varget with the bullet seated to touch the lands. the Match King bullet would not get this speed untill the pressures were a good bit higher ,very sticky bolt lift , hard ejector marks on a fully trued and lapped Rem 700
I think that you could probably get 2900 fps out of a 308 and 168gr bullets with a good barrel and plenty of pressure.
I have three .308W. 22"-24" of the shelf and a 26" Match barrel. All CM and all are showing signs of pressure at virtually the same velocity, which happens to be around 2670fps. with 190SMK. They're all most accurate around the 2630fps mark. Thought the Match barrel is 0.3" and the other two 0.75". Enough accurate for my needs. However one would expect the 22" barrel to fall behind by a considerable margin, but it doesn't.
"F-Class shooters are doing up to 2900fps with 190SMK
Using Lapua .308 brass, VN550 and Sierra 190SMK and a long throat. (3" AOL). "
WOW, I guess I didnt need to get my 300 WSM....
Im running in the mid 2600's with my 168 smk, and accuracy is good so I didnt try to go any higher, as Im only shooting 400 yards most of the time paper punching in the back 40.
Personally if I was to push a 190SMK at 2900fps I would choose .300WSM over .308W anytime. However it doesn't necessary mean that someone who's smarter than you or me can't do so. There are plenty of them who are and can do just that.
The smart one has to remember to use VN550/32"/long throat/3"+OAL.
The dumb one will try the same by using Varget/26"/normal throat/2.8"OAL and say it's impossible.
With this combo of course it's impossible.
Federal Brass: Federal match large primers; RELOADER 15 @ 45.0 grains; 165 seirra gameking HPBT; 2950 FPS all day long out of a factory savage tactical model 10 with a 26" barrel.
I used to load 45.5 grains but had to back down in the summer because signs of pressure. So I just backed down a little and I can shoot year round. Very accurate 5 shot groups at 100 yards 1/2 inch or less depends on what I can do that day.
One time and one time only I guess the moons lined up because I shot a perfect three leaf clover at 400 yards. I know no one would ever believe me because I didn't believe it myself and I did it. Good thing I had a witness that day.
Granted I usually get brass from a friend that is sniper on the swat with state police and all they shoot are Factory Federal Match ammo. I can usually get about five times before they show signs of wear.
