You don't have to neck turn or resize the Winchester....it's real 284 brass. Not 6.5-284 or something else.

Fryj00, you have a similar setup that I have. I'm running a 22" barrel with mrad brake, ptg bottom metal, manners stock but I'm running a remington long action. I plan on shooting 162 amax and 168 hornady bthp. I'm not planning on RL-17 though. I'm gonna try 4831sc and h4350. Have you tried h4350 to see if you can get better accuracy while maintaining close to the same velocity?
I have tried 4831SC and the loads were fairly accurate but just too damned slow. (~2600) I have not tried 4350 yet. Btw, you do know that the 162 AMAX has been discontinued? At least for now. Look at the 168 Berger Classic Hunter...wicked good BC and short OAL.
Yeah, I know. Unfortunate but I have managed to pick up a few boxes and I see them occasionally for sale. After they run out, ill run the bthp and since ill run a oal of about 3.1-3.2 I'm not concerned with running a short bullet.
I'm going to try h4831 to see what accuracy I can get but like you said, they'll shoot slow as hell and ill move on. I have heard good things about h4350 in a .284. Its almost as fast as the RL-17 and almost as accurate as h4831 and lets not forgot, a lot less temp sensitive then RL-17. Ill probably settle on that and stick with it.
Come to think of it, since length isn't an issue, why not run the 180 SMK's? They are cheaper than the Bergers and really slick BC. Of course, that assumes a fast twist barrel...
Although I have heard stories of the older Winchester brass being great, I haven't heard anything good about the newer stuff. I will still be using the Lapua for my .284. =)
fryj00, if you don't mind my asking what did you finally end up with for an accurate load? I know you were working on a load with H4831 that was slower than you were hoping & a load with RL-17.
Understand that I've little experience with Reloder 17...
That said, what I've heard from the folks I trust, is that RL17 is extremely "peaky" with pressure, and generally - when you see obvious signs of pressure, you're significantly over pressure. They say when you find real signs of pressure, you should back off at least a full grain (or more if ambient temperature is quite a bit less than the max temp you'll ever shoot in).
Again, this is not my personal experience - because I just haven't put in the time with that powder. Still, the advice above isn't just "here-say" from internet schmucks, either.
ETA: On my last 284 pipe, I did dabble with RL17. In that rifle, 52gr under a 162amax @ 2.950" left me with a big fat ejector mark.
HE, I have heard this as well but it's kind of a curious statement to me. So we say it's over pressure, yet it doesn't beat on the brass like other powders do at similar pressure. So what are we saying? That when the brass looks fine, we're in danger of shearing lugs or rupturing barrels? I'm curious to know how this powder is so different in that regard.
