JES will rebore a 7.62x54r out to use a .35 caliber bullet. Rather big impact on both ends.

Since so many people look to the odd ball "hyper velocity pistol cartridges" for use in restricted hunting zones, shotgun or pistol caliber only, the nature of the 303 and 54r having that nice cartridge RIM makes them interesting for straight wall wild cats.

True the .303 turns into the short shell .410 but with RIFLE chamber pressure, it should do wonders with over sized bullets. Like a real gun, and if cut to minimum length to suit being a "pistol round", it should do quite well.

54r seems to be the say way. Massively thick case body..

A .303 British cut to "pistol" length is called the .44 Magnum. Check out the dimensions to see why.

From memory, there is a "Factory wildcat" called the 9.3 x 54R, which is a "common" hunting cartridge in Finland and Russia. Pretty much like a .35 Whelan in performance. Also used in the "Medved" semi-auto rifle produced in Russia.

There is also a similarly-based 6.5 x 54R that is intended for "medium" / soft-skinned game. This is NOT the same as the Romanian / Dutch service round, which is also generally called the 6.5 x 53R.

Whatever you can do to a .30-06 or .303, .308, or 7.92 x 57 for that matter, you can do to a 7.62 x 54R case. The usual caveats about rifling twist rates, bullet weights, propellant burn-rates and pressures apply. Then there is the cost of all the custom work; stock, trigger optics and mounts, dies, etc.

The 7,62x54R is sometimes used to make the 6,5x53R Daudeteau cartridge that is used in rifles and carbines converted from the Mauser Model 71 bolt action for South America.

In Finland the 7,62x54R was necked down and known as the 6,3x54R hunting cartridge for small game. Soviet 6,3x54R had a heavier loadingAttachment 104708
