The ultimate wildcat round?

[RJW NZ]

I was just browsing the awesome pages for the Boys rifle by Enfield, and struck this image, it makes the .303 head look like a .177, I wonder what the muzzle velocity could have been with some hot loads instead of practice loads?

Although the .55/.303 was intended as a practice round, a good deal of work took place both in the UK and Canada with a Boys necked down to 7.92mm, which was intended for high velocities. Work took place mainly in 1941, but by mid 1942 it was obvious that armour was getting too heavy and the project was dropped.

On a slightly different topic, please don't be offended if I mount my hobby horse and ask that bullets are called bullets and not "heads"? The head of a cartridge is the other end, hence the term "headstamp"!

I'll go quietly now, but I am glad you liked the picture of my round on that site.

On the subject of wildcat rounds, anyone any info on the .303/ .243 (6mm musgrave) looking for loading dies etc, if they exsist.

I have one still in use. Best Fox splatterer i know. Dies from Die arama or Western firearms i think is their name, Ads on used guns .com.au.

Bindi2,

Is the 6mm musgrave the official name or does it come under anything else?, and whats the best place to get some reloading info.

303/243 same as 303/25 just 7 thou smaller. Use 303/25 loading data as a base point. ADI list modest info under 25-303 but start at a mid range projectile wt. i load 58gn Vmax to 3800fps.
