Hi All, I'm struggling a bit to settle on a final load so I can just go shoot the rifle at distance and put all this load development behind me and concentrate on practicing skills for upcoming comps.
After many rounds of chasing my tail with loads that were too hot and blowing out new brass..... I settled on a couple of loads to then do a seating test to tweak it and be done. But now I'm a bit more confused than ever on where to go.
Rifle is a JP barreled .260 Rem. I used two different bullets 130 Berger AR Hybrids / 123 Scenars and IMR 4451 for the powder. Neck turned Lapua cases, F210 Primers.
Here is the load dev for the 130 Bergers:
And then the seating test for the 130's using the 41.0 (target #9 above)
Below is the same test sequence with the 123 Scenars:
and below is the seating test for the 123s at 41.6 gr of IMR4451.
Did I choose the correct OCW node for the seating test? Any advice or suggestions to get this finalized? TIA.
Not sure if it matters, but the Chrono is a Lab Radar. The ES/SD for the initial OCWs were pretty good (but only 3-shot groups). However the final ES/SDs were horrible for all of the Seating depth options I tried.
