I have to quote bob. 1” groups are excellent. I can’t think of any improvement on that.
Iron sights?

With 1 inch groups why would you want to change ? After running military rifle matches for about 20 years and scoring 10's of 1000's of target , 1 inch groups with a K98k is as good as I ever saw . With PPU surplus quality bullets yet .

It's not that I'm trying to change or improve on that 1" group.
More that I'm trying to expand my options.
I'm just trying to work with the components I have on hand and currently available to create additional accurate loads, options are good, especially when components are in short supply.
Hunting season is coming and I want to use my rifle for something other than punching paper.

The Hornady SST's just happened to be a lucky find on a gunstore shelf (from before the current shortages).
I was able to get an accurate load, unfortunately they are unobtainium right now.

I picked up a 100 of the 139gr .323 PPU thinking they might make a nice, light target load and was just trying to see if anyone has had any luck with them.

Iron sights?

No, at 100yds with irons all I can see is a square. When i bought this rifle, back in '81, I was shooting iron sights with cheap surplus ammo at steel plates out to 300M at Ft. Hood with no problems. Unfortunately, those days are long gone.

I cannot bring myself to make permanent modifications to any of my milsurp rifles, but I replaced the leaf sight with the BadAce NDT mount and added a Vortex scout scope.

I suggest you find someone locally to trade their slower powder for your R15. Quite often, someone has a powder they purchased and didn't work out for them and is just sitting on their shelf..

I don't have any RL-15.
All my loads have been with W-748 and BLC(2).
W-748 is one of the Hornady recommended powders for 150gr+.

This may actually be the solution to my original question regarding the 139gr bullets.
Looking at Hornady load data for their 125gr .323 bullets, perhaps I need to try a faster powder, they recommend N-135 for their lighter bullets.
