The .240 Holland & Holland Magnum (also known as the .240 Apex, .240 Belted Nitro Express, .240 Magnum Rimless, or .240 Super Express) is a centrefire sporting rifle cartridge developed in England in the 1920s, primarily for use in hunting deer and plains game. This round has always been closely associated with the firm of Holland & Holland, rifle and gun makers of London, England, which has built more magazine and double rifles in this calibre than anyone else. A rimmed variant of this cartridge, known as the .240 Magnum Flanged, was developed for use in double rifles.
A number of Lloyd rifles were made in the period 1930 - 1950 for the .240 H&H cartridge, and David Lloyd took it as the starting point in his development of his .244 H&H Magnum cartridge, which uses the same distinctive .245 in (6.2 mm) diameter bullet, (NOT the standard .243 bullet) but fired from a much larger case.
The ballistic performance of the .240 H&H in factory loads is very similar to that of the .243 Winchester, with a 100-grain (6.5 g) bullet giving a muzzle velocity of approximately 2,900 feet per second (880 m/s). When it is loaded at the same pressure as the .243 WSSM using modern powders, the .240 H&H has the potential for slightly better performance.
Apex may refer to:
The apex was a cap worn by the flamines and Salii at Rome. The essential part of the apex, to which alone the name properly belonged, was a pointed piece of olive-wood, the base of which was surrounded with a lock of wool. This was worn on the top of the head, and was held there either by fillets only, or, as was more commonly the case, was also fastened by means of two strings or bands, which were called apicula (Festus, s.v.), or offendices (Festus, s.v.), though the latter word is also interpreted to mean a kind of button, by which the strings were fastened under the chin (cf. Serv. ad Virg. Aen. ii.683, viii.664, x.270).
The flamines were forbidden by law to go into public, or even into the open air without the apex (Gellius x.15), and hence we find the expression of alicui apicem dialem imponere used as equivalent to the appointment of a Flamen Dialis (Livy vi.41). Sulpicius was deprived of the priesthood, only because the apex fell from his head whilst he was sacrificing (Valerius Maximus i.1 §5).
In anatomy, an apex (adjectival form: apical) is part of the shell of a mollusk. The apex is the pointed tip (the oldest part) of the shell of a gastropod, scaphopod, or cephalopod.
The word "apex" is most often used to mean the tip of the spire of the shell of a gastropod. The apex is the first-formed, and therefore the oldest, part of the shell.
To be more precise, the apex would usually be where the tip of the embryonic shell or protoconch is situated, if that is still present in the adult shell (often it is lost or eroded away).
The phrase apical whorls, or protoconch, means the whorls that constitute the embryonic shell at the apex of the shell, especially when this is clearly distinguishable from the later whorls of the shell, otherwise known as the teleoconch.
Comparison of the apical part and the whole shell of Otukaia kiheiziebisu:
Where this feature is present, the space under the apex of a patellate or patelliform (limpet-like) gastropod shell is called the apical cavity.
