Which Big Bore cal for LR sport/hunting?

[Porker]

Guys...is the Allen magnum more or less an ackley improved 375 H&H? I'm from South Africa which means Allen wont be able to help me....I need to go the local route.

No, the AM is not based on the 375 H&H case.
My suggestion would be to look at the 375 RUM or the 378 Weatherby if you want to be able to use store bought ammo and a standard magnum action.

Thanks Rider,

To what distance will the 375 RUM and 378 Weatherby shoot MOA? Can they
be regarded as good "sniper type" calibre's at 1000 yards?

I can't answer the first question as I don't have any experience with either cartridge, and it would depend on how well the rifle was put together and on the ammo and shooter.

I can say that mine and my buddy's 375 H&H rifles will shoot into 1/2 moa using the Barnes 235 TSX and Varget powder at ~2900 f/s. Mine rifle is a Win M70 and his is a Sako.

For the second question I have no idea.

I'm afraid I haven't been much help. Sorry

+1 . The rum or an improved version will hold up to about 107 to 112 grains of powder.

The 378 weatherby will hold about 125 grains of powder, so with the right bullet you should
be able to do what you want,

Or look at the 416 Weatherby with some custom bullets.

All of these rounds can be very accurate and if you are a turret twister trajectory is not a
problem.

Never heard of a Mach 5? but I will have to build a "disguise" sniper in the form of a hunting cal, or it wont pass....

so...will the 378 weatherby do the job at 1000 yards? won't shoot that flat...but not a concern if it's still accurate??
