Sounds like you need to get something like the .358 Winchester or 9.3x57 mauser but of course with those large numbers the local licensing department might have kittens .The older I get - the more sure I become that if I was confined to fairly close-encounter shooting in woodlands and semi-urban areas which constricted shooting distances, I would seriously want a wide bullet with a soft round nose and travelling at a sedate speed, just fast enough to hit and hurt and expand. In this case, trajectory would not be such an issue, but getting to know what the cartridge delivered in tems of rise and fall would soon cure that with the rangefinders of today. The slower missile would also be a much better brushcutter, and in the zest for more speed and different bullets to match, a lot of the advantages of the old cartridges have been forgotten.
However - apply the modern components to an old fashioned style cartridge in order to weed out the irritations, and it might be extremely useful. We have lost some fine tools.
Just goes to show Barnham was right.......................... there is one born every minute .Thanks, send them my way they are super investments.
Whoops sorry the .280 Ross became commercial in 1907. I notice that wiki has the velocity of the 140 grain at 2900 fps yet the Ross book states thats' the velocity of the 160 grain FMJ target round and the velocity of the 140 grn bullet was 3100 fps . Charles newton it seemed developed his first High velocity cartridge in 1913 which again predats the Savage 250-3000 and it's 87 Grn bullet designed by Newton by 3 years so I find it amazing that you regards it as one of the first after Newton had several Hi velocity cartridges intorduced before the 250-3000 and I am sure if we look into Europe we would find some more.The .250-3000 Savage is a rifle cartridge created by Charles Newton in 1915 and is also known as the .250 Savage. The name comes from its original manufacturer, Savage Arms and the fact that the original load achieved a 3000 ft/s (914.4 m/s) velocity with an 87 grain (5.64 g) bullet.
The .250 Savage was the first American cartridge capable of achieving its 3000 ft/s (914.4 m/s) velocity, and was created for use in the popular Savage Model 99 lever-action rifle. Achieving that velocity may have been the reason for the choice of the light-for-caliber 87 grain (5.64 g) bullet. The cartridge has a pressure limit of 45,000 CUP set by SAAMI.
I agree that bullet construction must be considered, but with normal UK stalking calibres using quality hunting bullets you should be OK. It is only with the big case wildcats as you say,were you would need to experiment carefully to ensure you did not get bullets blowing up on impact.Tahr agreed, but make sure that it's not so fast that you risk bullet blow and failure to adequate penetration - ie keep impact velocities below say 2800 to 2900 fps. With the vast majority of normal stalking cartridges this is not an issue - may be an issue with light bullets and bigger cased cartridges.
??Of course that fine American Company John Rigby and Sons had an early higher velocity round also the .275 Rigby copied after the 7x57.
