Bow, first of all, Welcome to the Brotherhood!!
as to your question on the 7828' and 168 LRX, or LR nosler version. The 168 LRX Barnes bullet has a lot of bearing surface. That being said, the push needs to be a slow and steady one, such as H1000, RL25, or similar. The 7828 is an awesome powder, and is definitely a player in the world of the STW. However, and I can feel some frowns already, I feel it is BEST suited for 140-154, maybe, 160 class bullets. I know it's the only thing you have now, and that alone really sucks. I had a STW at one time that absolutely loved 7828' and 150 grain CT, or Partitions. That rifle was a straight 9 twist, and would shoot anything I put into it, but it shot the 150's into a dot all day, and 7828 was the fuel.
You can use the 7828, and your accuracy will come near the top end, as that bullet needs RPM's to stabilize. You won't have trouble with a Berger, or a Nosler, but the LRX is a REALLY long bullet.
As a example, my 7 mag will not stabilize that bullet, but when shot from a STW, that has the same twist, it does stabilize. That being said, with the 7828, you MIGHT hit pressures before you get the speed you want, or maybe even the speed needed to make it go to sleep.
" BlackSheep", is the 168LRX guru here on this site. Maybe he will chime in and give you the " Secret " formula! good luck with your new rifle, and don't be afraid to ask a question or two. Once you wrap your head around the STW, you are hooked for life!
