Hi guys, yes 223AckImp, it can be a bit dangerous getting too close to the big boars. Not long ago I talked to a lady pig hunter (74 years old) who told me about an incident where her dogs could not hold a pig, the pig went for her so she climbed a tree, the branch she was on broke and she fell onto and straddled the pig. In a flash the pig ripped both her archillies tendons, it took her a year to recover. To top it off she later had a similar incident with a wild Bull cattle beast, branch broke, Bull ripped her from knee to groin. I currently guide in the valley where the lady was ripped and the animals certainly are dangerous.
Glen, sounds like you are enjoying planning your next project rifle. My long range medium bores include a .338 Win mag (225 grain SST at 2980fps, 9.3 RUM, (286 grain Partition at 3000fps or 225 grain RWS DK at 3178fps) and the .375 RUM (260 grain Accubond at 3100fps). The medium bores certainly work well on pigs and allow some room for shot placement error. The only bugbear is that on lean animals like Fallow, goat or skinny Reds, the medium bores are not as fast killing as my 7mm magnum unless an extremely soft bullet is used.
If I am to be honest about my eperiences, I have shot over 6000 head of game using every calibre and cartridge available and autopsied and catalogued every kill with the goal of exploring humane killing. For many years my wife and I did all of this quietly, writing a book to compete with COW. Now, as the book is near its end and with the hunting business up and running, I have begun to become more active in cartridge discussions.If your'e with me so far then I will add my two cents about some of the choices faced when choosing a medium bore.
With most bullets, the .338 does its best work on lighter medium game at velocities above 2800fps. Below this, game hit may show no signs of wounding and run for 100 plus yards. The .338 really comes into its own on game over 90kg (200lb) On game of this size, the .338 is more forgiving at velocities of 2600fps with most bullets and down to 2400fps with the SST. An exception to this rule is on compact game including boar and bear. A light boar of 60kg (130lb) will fold up with a bad shot from the .338 and allow the shooter time for a follow up shot.
A side note: The 300grain SMK is slower in expansion compared to the SST.
I would definately choose the .338 RUM for larger animals but not for use where lighter animals may be encountered and would instead opt for the more versatile 7mm RUM. The 7mm never really ceases to produce the kind of kills that you never forget, rather than the dissapointment from a cartridge that you hoped would strike like a patriot missile but only gave average results.
The .375 is a good cartridge as it has a huge frontal area and good availability of soft bullets which work well on light game, at the same time it has stout bullets for heavy game. That said, there are no .375cal bullets designed exclusively for long range and it just isnt the same for long range enthusiasts as the .338 which has some military nostalgia and appeal.
Hope this helps.
