6.5-284 Norma

I have used both H4350 (47.0 grn) and H4831SC (51.0 grn) with 140 VLD's and the Sierra 142's. Both have shot groups in the 2's and velocity range is 2920-2950 depending on components. 28" Criterion barrel.

47-49 grn (depending on barrel) of H4350 works great with 140 class!
I shoot 140 BT or Accubond for hunting and 140 RDF, 140 HPBT and 140 Match Burner for long range target and all loaded with H4350 powder. Velocity is usually 2940-2970...again depending on barrel.

48.48 gr H4350 worked great with Sierra 142s. 5 rounds into 0.96" at 600 yds. Now shooting 49.3 gr N160 with same bullet.
Play with seating depth a lot to find where the gun is happy.
CAUTION: those loads are STOUT but in Lapua brass, no major issues aside from short life.

I have had excellent results with Retumbo(57gr@3000FPS),H4831sc(53gr@2950FPS), and R26(54gr@3050FPS) with 140-143gr class bullets, 26" barrels. All using Fed210M primers. All produce .25MOA/SD<5. Retumbo is my go-to for hunting with excellent temp stability and barrel life. Work up loads starting a few grains lower!

Seemed to have found the load my rifle likes with the 127 LRX. All reloading disclaimer caveats apply, work up load from minimums if using. WLRM primer, Lapua brass, 53.0 g RL26, COAL of 3.00. I might play around with seating depth/primer after hunting season gets over, but it's currently under .7 for 5 shots @ 3080 fps in a 25.125" barrel, so we'll let her rip for now. 53.0 groups well with both the 52.9 and 53.1 (ES between 8 shots on those 3 charges was 28), so the node gives a bit of room for weather swings. Thanks for those that provided help along the way.

Interestingly enough, the LabRadar would suggest that the BC of the LRX is actually closer to .487. We'll be taking out to range to test that, but if true, that would represent a nice little bump over the advertised .468
