Lovett's gun center in kitchener. They have .308, .303 Mk 7, 7.62 x 54R, 30.06, 8mm, 6.5 x 55 Swedish, .30 M1 Carbine and .223.
@sunray: As soon as the damn strike is over and i get my rifle i will check and hope they still have some crates in stock.
Thank you! I just called them and unfortunately they don't have any 7x57mm Mauser in stock.
That is a pretty good deal on the .303 British though, I would buy a case now if were you.
I wouldn't worry about slugging your bore unless you end up having major problems with accuracy. A .311" bullet is about ideal for a .303 British cartridge.
Checking the headspace isn't a bad idea, but may not be necessary either if you are buying a rifle that is in really good condition.
Remember that the Lee Enfield's were battle rifles and meant to have somewhat generous chambers and headspacing to compensate for battlefield conditions.
You can run a rudimentary test on it yourself if you don't have proper gauges.
First, remove the extractor from the bolt.
Then apply a layer of masking tape to the base of a cartridge (the tape should be trimmed to the dimensions of the cartridge head.)
Preferably, you would be using a dummy cartridge no longer than the max. OAL.
Insert the cartridge (with the taped base) in the chamber, and try closing the bolt gently without forcing it.
It will likely close on one layer with no problem, if it doesn't, your headspacing is really tight.
If it closes on two layers your headspace is getting iffy, if it closes on three layers you should not fire the rifle until you have had it properly checked with the appropriate gauges (preferably by a good gunsmith.)
If it is still excessive, you would then want to replace the bolthead with a higher numbered bolthead and check the headspace again.
Chances are, your rifle will be fine if it is in good condition. If it isn't, you will want to look at it more closely and maybe have a competent gunsmith examine it for you.
Good luck with it! I hope it shoots well for you.
P.S. The thing I do strongly recommend is to disassemble and thoroughly clean your rifle before shooting it.
I clean with a mixture of 50/50 Kroil/Hoppes #9 for general cleaning, and then lube the metal and bore with Break Free for short term storage.
I remove the excess lubricant from the; chamber, bore, boltface and firing pin before each shooting trip.
