Re: 2900 Fps .308?

Im currently shooting 51 grains of H380 with a 168 Berger VLD out of my Savage 12 F/TR with no signs of excessive pressure and I'm getting 2950 fps. Thats with a 30" barrel, also. I got that load out of a Sierra handloading manual. It was listed under compition loads for the 168 SMK. And that wasnt even the max load listed! Oh yeah, the gun shoots under a half-inch groups, too!

OAL is 2.915 and yes on the Chrono. The Bergers are a longer bullet than the Seirra Matchkings and have a much better BC.

My thunderstick likes 42.5 grains of IMR 4064 topped with a 168 grain sierra match king. not sure how fast its going but it can print sub inch groups if the shooter does his part.

Re: 2900 Fps .308?

I am doing an experiment on the same. I have a barrel purchased from this forum, a broughton that will end up as a tight neck .308 using the Kiff hand throater. I plan on using 208 amax and 210 Berger. Both will be loaded to 3.1+ col. I'll try H4350 and Varget and post results. Barrel length will be determined(26" or so.) If I can get an accurate 2600 fps, I'll scream like a school girl!

Re: 2900 Fps .308?

When I first saw this thread I rolled my eyes and thought yeah right.

After working with the 26" Hart barrel my eyes are a bit more opened up. Now I didnt run very many 168's but using factory federal gold medal match ammo the reading were just under 2800 FPS and the brass and primers looked good. Extraction was easy as well.

Now like I said, I didnt really work much with the 168's but I was able to run the 178's at just over 2800 FPS with no loose primer pockets, no no primer cratering and no ejection marks as well as easy extraction. The same was true of the 190 VLD's at 2750. So it would be logical to conclude that it if I can run over 2800 with the 178's, one could run 2900 with the 168's. I am also not talking about running extra powder either, I am talking about published loads. It just seems as if the barrel delivers more velocity.

Now for the catch. I have not been able to run the high velocities with any real accuracy and certainly no repeatable accuracy. Maybe its my barrel or maybe it is that the 308 is happiest at traditional 308 velocities so that is where I have ended up. If I want 300WSM velocities, I will break out the 300WSM.

Let me hear your results, especially if you try some rl17.
