7.7 X 54mm

[bouletbill]

Hi All , does anyone know the method of reducing the .303" chamber by 2mm so as to create a non military calibre ? as was done in Aussieland , which they called 7.7x54 and is still required in France , called .303Sport .

Go for it. ..... It is could 303 Sporting in France, I have a No4 and a MkII in it. It is a very nice round to shoot.
Cut one turn of the barrel mounting thread. Which is about 2.65mm, and re cut the extractor grove, just as the bindi2 said.
Cut the same length off the bottom of a 303 btit die for reloading. Use the die the full length re size after you have anealed fired cases but not necessary with new.
the reloading problems you would have with the 303 brit will be the same i.e crushed shoulders.
Use a lighter bullet, about a 150 grain.
Learn French and there is plenty info on the WWW.

Thankyou David , (& Bindi2) , you make it sound so easy ! just like learning French (ho ho) . Now , after I've used the hack-saw and Stillson , will I have to get it re-proofed ?

In the UK - yes

In France YES. I would thinl most countries it is yes.
I would get a pro to do the work.

Here is a link for you to translate.

I found this elsewhere. I have no idea how accurate it is. But I think it is interesting.

NO in the USA----anybody with a Stillson and handgrinder can build anything he wants and pass it on to the next fool without Proof.

Proof does not insure much of anything. The worst offenders in the US market place have to be the Lee-Enfields that the Brits unloaded.

Hey ireload2 , if you all don't like our L-Es , can we have them back please !..... at the prices our gov'ment gave them away for .

Seriously tho' , mil-surp is sold off in "as seen" condition and its the dealers responsibility to retail it with honest appraisal . It would be interesting to know how many are still in store . I suspect that most L-Es appearing now are third -world surplus .

Thanks for the diagram , yes it is interesting .
