dpcdI Need a 338/303 British Reamer
I need a 303 British case with a 338 bullet, finish reamer. I also put this in classifieds.

Bill LeeperCan you not just use a 30-338 reamer and throat separately? My 30/338 reamer has more than sufficient ND to accept a 311 bullet. Regards, Bill

setters5I gotta ask why? Are there any quality bullets in .312?

dpcdBecause someone wants one; reason enough.
30-338 is way bigger than a 303 British. I have nothing in 338 small enough to fit through a 303 chamber and make a throat; all my 338s are bigger than a 303 case.

Were that the rationale there would only be about 10 or 15 caliber selections and that is all we would have
Different calibers makes the gun world go-around.

ArnietI think some of us are reading it backwards. I think the customer wants to shoot 338 bullets using the 303 case. Why not?

setters5I guess I was reading it backwards, a .338 bullet in a .303 case makes more sense.

dpcdI guess the nomenclature should be 338/303 British; the caliber comes first.

Bill LeeperYes, I misunderstood as well. I was sure you said 303/338 and assumed you were rechambering a P14 or something. Regards, Bill

Not if Australian or English, hence 303/25, 577/450, 450/400 etc.

dpcdOk, good; yes I considered that and I have bought them before but they cost almost as much as a reamer.

ColoradoMattI think I recall reading an old Ken Waters article in “Rifle Magazine”, where he had the ruined bore of an early Rigby 98 in 303 rebored to .338”. It was a very practical way to keep the old girl shooting.

FISH!!
Heed the words of Winston Smith in Orwell's 1984:
"Every record has been destroyed or falsified, every book rewritten, every picture has been repainted, every statue and street building has been renamed, every date has been altered. And the process is continuing day by day and minute by minute. History has stopped. Nothing exists except an endless present in which the Party is always right."

I remember that as well.
There use to be quite a few 303/350s in Australia when the 303/25 and 303/270 were at their peak. The 303/25 factory loads were very common and you could buy them at petrol stations when you went into the bush. 303/270 not so and maybe because it was so easy to reload. The 174 grain was pulled from the 303 ammo and case necked down and 100 grain bullet seated on top of the cordite load.

dpcdI personally would make it in 358 caliber, and I can do that one, but the client has thousands of 338 bullets he is trying to shoot up. So far he has a 338 RUM, a 338 WM, and a 338-06.
He is now looking at his mint Siamese Mauser after I mentioned I had a 33 WCF reamer. I said no.

matt salmI’ve done several chambers with the parent reamer, a chucking reamer for the throat (available in .001” increments, and the proper throating reamer. It works very well as the chucking reamer will self center and has the same 45 degree chamfer as most chamber reamers have on the neck portion.
Shoot straight, shoot often.
