I load, 43.7 grs of VhitaVouri N-160 with, CCI 200's at, a COAL of, 2.685 about, .040 "Jump" ,in my Tikka 1-10, T-3 SS 22 inch bbl., .243 Win for a chrono'd, 3,130 FPS ( it's NOT, a Max load but, sub 1/2 MOA ) Rem cases.
And 43.5 grs of N-160 with CCI 200's with, the 87 Berger HVLD's W/ a COAL of, 2.710, going, 3,110 FPS (same Gun ) ES of 11 with, this load, and shoots in, the .2's and 3's ,.. you PAY for, accuracy !
You could also Try,.. IMR 4350 with, these 87 vmax Bullets starting at, about 41 grains for this weight, bullet.
I use 42.3 grs of, IMR 4350 with, the #1515 Sierra, 80 grain Varmint Blitz Bullet going only 3,000 FPS or so ( But it's a sub 1/2 MOA load, too ).
