I came into a barrel chambered for the 6mm Musgrave threaded for a Martini Enfield or SMLE action and am trying to decide whether to put it on an action. I would like to hear folks' experience with this caliber, and what rifle it was on.

taking a big o'l WAG here, but I'm guessing you got a 243/6mm Rem in a 303 type case.
maybe another 50-100fps?
shrug.

After the World War 2 a great many South African 303s were converted to 6mm Musgrave and, sadly, some older, family-heirloom SMLEs. Musgrave was a very successful family-owned firearm company.
It is not as fast as the 243 Win and the rifles were invariably a bit inaccurate due to the action, but they accounted for a great many springbuck on driven hunts.

The Musgrave is a less powerful .243, but not by much. Bullet performance was about 2800 fps with a 100-grain bullet. Still a potent killer for smaller game, remember that the factory load for the .250/3000 was the same. Is it worth screwing onto the OP’s action? That’s up to him.

I believe this is what it looks like.

I think the Ellwood Epps gunshop in Canada did the same thing by necking down the .303 British to .243. The final dimensions probably varied a bit from the Musgrave, but I'm sure performance was the same. There's probably an Australian version also -- you'll find such anywhere the British Commonwealth left some Lee Enfields behind.

I have several years worth of Man Magnum magazines.
I remember several articles on the 6mm Musgrave.
If I remember right, it was quite well thought of for smaller antelope, and didn't ruin as much meat as a full house 243.

I say build the Martini.
Years ago, I had a Westley Richards switch barrel falling block that had a 450NE barrel and a 6mm Musgrave barrel.
I shot the 6mm quite a bit at the range but never once touched off a 450.

One built on a smaller Hagn action would be about ideal but one on a nice Martini would be quite nice as well.

That is the direction I am leaning, especially since the barrel is already screwed into a bare martini action.

Can't wait to see your Musgrave in action, Dave!

Not sure if it would be possible (or worth while) shipping them over, but I have 5 boxes (100 rounds) of PMP once-fired brass, still in the original boxes if you are interested.

Hi Peter.

Thank you for the offer, and let me see if I can figure a way to get them here to the U.S. without you having to mail them. How much do you need to get for them and where are you in South Africa?

I found a set of dies and found that I can easily neck down .303 brass by first reducing the neck to 7mm by running it partly into a 7mn-08 die.

Yes, that’s what I did too.
Another reason to like the 6mm Musgrave
