.240 flanged nitro loads
Gentlemen

A few months back I acquired a Holland .240 flanged nitro and it's time to get her ready for deer season.

The gun was made in 1936 and proved for "cordite 31 1/2 100 max". Does anyone know the stated velocity and bullet shape of the load of the day. I know the prior owner used 41 gr. RL22 and a pointed Speer bullet at supposedly 2500 FPS. Don't know much more.

Any help is appreciated. Thanks in advance.

Don:

Don't have info for 1936 but can bracket that; I have copies of the 1925 and 1955 Kynoch catalogues.

In the 1925 catalogue, the loads for the .240 Flanged were listed as "100 gr. Metal-covered, Solid Pointed, Soft-nosed Pointed or Copper-pointed bullet." The illustrated bullet looks like what we would call a semi-pointed today. The ballistics table lists the latter two bullets, with 38 grs. Smokeless giving 2850 fps at 18.0 tons pressure; barrel length was not specified.

In the 1955 catalogue, only two bullets were listed, a 100 gr. Semi-pointed soft point and the 100 gr. Copper-point. The powder charge was listed as 38½ grs. of Nitro-cellulose (i.e., not Cordite), for 2775 fps from a 28" barrel. No pressure was specified this time.

I have two .240 Flanged rounds in my collection, but I'm not sure of their vintage. One, headstamped HOLLAND .240 , is loaded with a relatively blunt semi-pointed bullet, with a nose profile about mid-way between the modern Hornady 100 gr. .243" PSP and RNSP bullets. Overall length is 3.238". The other, headstamped KYNOCH .240 , is loaded with the Copper-pointed bullet. This has a very sharp point, similar in profile to modern plastic-tipped bullets such as Nosler's Ballistic Tips. Overall length is 3.245".

Hope this helps.

Cheers, Al

The H&H rifles for the 240 flanged magnum introduced in 1920, were made for a 100 gr jacketed soft point spitzer shaped bullet, .245 dia bullet, but .243 dia should work fine. The factory load was 2900 fps but I don't know what length barrel it was shot from. This is almost identical to the 243 Winchester!
Proper case length is 2.50" , and loaded cartridge length is 3.25"
