Looking back through my records, I came up with the following.
57.0 H4350 Win. cases - WLR primers - 180 grain Power Points
7/8" at 100 2 1/8" at 200 just over and just under 2700 fps
That 100 yard group is probably a bit on the exceptional side and the 200 yard group is fairly normal if I do my job.
55.5 H4350 Win. cases - WLR primers - 180 Failsafes (the real ones, not the ones polluted with moly)
7/8" at 100 and 2750ish
1 1/16" at 100 and 2685ish (different day)
Those are pretty much normal with the load.
These are results in my rifle (24" Model 70 Classic), so as always, you need to find what works safely for you.
Also, I have found that when I use the 57.0 grain load with 180 grain Hornady BTSPs, the speeds (and, it would follow, the pressures) increased significantly, thereby pointing up the validity of reworking loads when changing bullets.
In the past, I have felt that I saw a bit better accuracy with IMR4350 while using a grain less than the H4350 for similar speeds. My last batch of H4350 seems to want to be dropped back the grain to the IMR4350 load of 56.0 grains to keep the speed the same.
Hope that helps.
Try the Hornady SPs, youll get better accuracy.
