Still working with the 26 Nos.
The 140 NAB over 85 gr. WC872 shot .4" at 3,214 fps.
The 140 VLD over 88.5 gr. WC872 shot .56", didn't get speed, probably 3,250 or so. 3,100 is reportedly the design ceiling for Hunting VLD's, so I don't use them for hunting.
The 139 Scenar shot half inch over 79 gr. n-570 at 3,316, SD 32.
The 127 LRX over 91 gr. US869 shot over an inch at 3,446 fps., no signs of pressure. I've not gotten stellar accuracy from that bullet, may need to jump it more, adjust the load.
130 SSII over 80 gr. n-570 shot a fairly good group at around 3,400, but had hard bolt lift. The SSII has a very long shank, probably too much friction for that load.
120 gr. Swift A-Frame over 80 gr. n-570 shot an inch or better at 3,565. Good speed, average accuracy. Not a high B.C. bullet, may not use it.
So far, seems WC872 and US869 with 140 NAB/VLD's at 3,200+, 120 mono's, (TTSX/E-Tips) at 3,450 are best performers at half MOA. You add the 139 Scenar over 79 gr. n-570 at 3,300+ to the half MOA club. 139 Scenars also shoot good with 869 and 872.
I've yet to try 120 mono's over n-570. I'm thinking n-570 may outperform 869 and 872, at least QL thinks so. Fast doesn't mean accurate. Maybe I'll get a final combo before the barrel is toast...
At 500 rounds, maybe getting close to half way. I'll shoot it as long it'll go half MOA, regardless what the Hawkeye shows.
