best 308 bullet for 1,000 yards

[JarheadAZ]

You could go to the .308 with the SRA 175SMK, Rem brass. CCI BR-2's, and 42.2 gr of IMR-4064. 2.814" OAL if feeding from the mag, else .020" of the lands. I would use a 26" barrel for optimal powder burn, and 1:12" twist should be highly adequate.

My own preference is for the .260 with a 28" 1:8" barrel. The NOS 142 Accubond Long Range with 44gr of H-4350, CCI BR-2, Win 7-08 brass necked down to .260 specs, jumped .010" to .020" to the lands. Adjust charge to find exact node. This rifle has shot strings of consecutive X's at 1000yd.

I am working with the .280 Rem (very slowly, so far). The barrel length is still under consideration, but at least 26", with a 1:9" twist. Remington brass, CCI BR-2, SRA 168SMK jumped .010" to .020", and somewhere around 50-55gr of H-4831SC. This load is an approximation based on work with 120, 140, and 150gr bullets.

The .280 is capable of accuracy a good bit further beyond 1000yd. Note that although this is considered a long action chambering, the empty case will extract and eject in the average short action. For single feeding the S/A will work, except for when a loaded/unfired round must be extracted/ejected. This can still be performed as long as the shooter is willing to trip the bolt release and withdraw the bolt a bit further.

Jarhead, why not a 284?? I shoot the 162 AMAXs and use H4350. I have shot this combo out to a mile with a 28" barrel. They are good for over 2000rds and are very accurate. The 168 Bergers are great but the SMKs suck for BC. Don't get me wrong, there is nothing wrong with a 280 but I just feel the 284s shorter fat case works better.

it will be for when the 6.5x47 barrel is shot out,,the 30 inch length is for sight radius,,,I was making hits on 15 inch gong at 1000 yesterday but want a longer lasting caliber next time,,it is just for kicks to break out on fun shoot days,,


would you bet against a hit with 5 tries on 15 inch plate at 1,000 kinda rifle,,,just for fun

Not at all, very doable. Now I understand.

I have a 30" Heavy Palma chambered in 6mm Competition Match that is baaaaad azz, load it with H1000 and a 115 DTAC, smoking combo. It will give you at LEAST 4000 rounds of accuracy.
