7X57R + Vihta N555 load with Quickload

[gerardus]

Hi all,
does there anybody here have a recent version of Quickload? I wonder if Vihtavuori N555 is in the latest version (3.9?)
If so, I'd be grateful if you could run a couple of simulations with the following parameters:

Caliber:7x57R (Rimmed, not the Mauser)
Powder: Vihtavuori N555
Cartridge length: 2.992"/76mm
Case capacity: 61.5 gr H2O
Barrel length: 23.6"/600mm
Bullets:
- Nosler AccuBond 140gr #59992
- Hornady SST 162gr #28452

Thanks,
Gerard.
