Chirs,

Well done.
"How proud should I be of it ?" - Very

Sounds like you have a 240 Apex Bolt Action made on a (probably) Mauser 98
action.

14/9/1924 may be finish date or delivery date.

If ou post the Serial Number, I wshould be able to give you a date of Manufacture.

f you contact Hollands with the details of the gun including serial number,
they may provide you with a copy of the records.

240 Apex was a proprietary round by Holland - ie only really made by Holland.

Although you may be able to buy ammo, it really is a reloading proposition
which isn't a problem if you can get dies etc as cases can be made.

The bore - I would strongly suggest you get the bore slugged by a gunsmith
especially if you plan to shoot it.

240's had a bit of variiation in bore size so you need to know what it is.
Could be from .243 - .246.

If .243, great, you can use .243 bullets, if .244 and above, we have worked out
how to make bullets for it.

Hope this helps. By all means post questions again if I have not been clear
and you want further explanation.
