Nino,

Do you have a chronograph?

140gn is super heavy for this compact calibre, and marrying it with N135 is way too fast. You can shoot 140 in Grendel, but even with a better suited powder it will be slow and with a rainbow trajectory. The lighter weights work well: 95-123gn.

I have not used VV but 530 and 540 appear to be the optimum powders, both on their website and when looking at equivalents. It's a pity VV does not post pressures with their 24" test barrel.

Very nice looking rifle - what do you plan on shooting?

Hi Klem.
This morning I went back to the range and tried some reloads made with S. & B cases, CCI 200 LR primer, VW N135 powder at 24.0 and 24.5 grains. The ammo isn't bad but still not great. Just this morning my chronograph decided not to work and so I don't know how fast they developed. Judging by the primers there must have been no excessive pressure, they are not crushed or cratered. The recoil was not excessive. The next reloads I will do with the same components but with a 108-grain Lapua bullet, very long...
Thanks to all for the help...
Ciao
Nino
