I'm looking to take my .308 out to 1000 (and possibly beyond). I'm shooting a Remington 700 SPS Tactical. 20 inch barrel, 1:12 twist. I'm getting sub .5 MOA from 100 out to 600 using my handloaded 168 grain AMAX. I'm using 42.7 gr of AA2520 with CCI primers. Anyway, I keep hearing "if you want to take it to 1000, you'll need to use 175 gr and higher". I know there's gotta be some people out there that are shooting 168 gr to some success. I have shoot plenty, I've just never shot a .308 past 600 yards. Part of the problem is finding an area that will support 1000 yards. The are several reasons for me not wanting to go up in weight. The first one is twist. I don't have the 1:12 twist, so I don't think the higher weights would stabilize enough. One other reason is the amount of powder, bullets, primers .... etc that I would burn up trying to work up a load that may or may not stabilize with my current barrel. Another, is the problem with finding a good area to shoot. So, difficult to work up a round specifically for 1000 yards. Anyway, if there are others out there using 168's with some success, I would like to hear about what your using.
