My FEO, on doing an inspection, noticed one of the rifles stored with bolt in.
I told him that was the "rifle of the day".
"What do you mean?" he asked.
So I told him: "If I need a rifle in a hurry, I want to be able to simply grab that one, and go. Not be faffing about unlocking multiple cabinets to retrieve various component parts, with the associated risk of ending up with the wrong bolt in the wrong rifle. So at least one rifle has to be ready to go at all times".
He thought that was a valid point, and said no more about it.
So, I suppose it all boils down to how "ready" you need to be, in order to be able to fulfil your role as a deer manager. If the owner of the land over which you shoot calls you to say there's a fallow buck tangled in fencing wire, going ballistic and very stressed, how quickly can respond? And how would you feel if you got there and found you had incompatible bolt and rifle?
All my stalking kit lives in a "grab bag" by the back door, and at least one rifle is ready to go at a moment's notice.
