Your kit, in order

The whole armoury, on file.

Rifles, pistols and shotguns with their optics, mounts and fitted kit. Your firearms certificate and shotgun certificate sit beside them - every slot, the calibres each one permits and the ammunition allowance against it, so you always know where you stand.

Coriolis Precision armoury - loadouts, guns and equipment
Every round, logged

Find the load that shoots.

A range logbook and shooting diary that earns its keep: every outing, chronograph string and group recorded, with rounds coming off your stock as you shoot them. Load development ranks your charges by spread, so the data decides. No guesswork.
