Hello guys, been looking to buy .308 reamer and go gauge to chamber my first rifle. Would like to know if there is anybody in Canada who sells them. One of the search mentioned Winchester 070 for a PTG Canadian distributor. Sent a pm but no answers yet. In the listings for reamers they are saying "Finish reamer", does that mean you have to start with a "roughing" reamer then use the finish one?? or the finish reamer is good from start to finish? Since this is going to be my first attempt, I would really like if anybody in the Ottawa region is chambering a rifle for this season that I could go and watch him do it. Tks
 
Sending a PM to 070 really doesn't work well, best to email him: thereamerguy@yahoo.ca He will answer an email.
Your second request finding some one who doesn't mind you over seeing a chambering job not so easy. Must be a trade secret [LOL] or a case of nerves!
You tube is your friend. Look up rifle chambering, quite a few on Remingtons. Only real reason behind using a rougher reamer to start with is less wear on your finishing reamer. So if you are really into production work a finishing reamer will do a fine job from start to finish.

Last PTG reamer that I bought was .006" undersize, total garbage, never again. Nothing special, just a plain old .308 Obermeyer match reamer.
 
JGS has excellent reamers, they are my first choice followed by Manson.
You don't have to have a rougher but it will save alot of
wear on the finish reamer if you end up cutting alot of chambers, if only for few
chambers a finish reamer is all you need. I would practice quite a bit before attempting
to chamber rifle, there are also a bunch of different chambers for the 308's.
I sure hope you have some machining experience.
Good Luck

I used a reg drill bit to remove most of the metal first and then finished with a Finishing reamer to save wear - worked fine - ;) RJ

You could check with Manson reamers if he's got some in stock, when they are its only a few days to get them out of the US. I got 3 and quality seemed quite good, cut fine and were on size.
 
I think Gary Eakin at Bighorn sales aka thereamerguy@yahoo.ca is selling Manson tools now, at least when I ordered a bushing that is what he was selling. I'm afraid I'll have to echo Maynard's thoughts on PT&G as the last reamer I got only cut on 2 flutes and when I sent it back they charged me $100 american for a regrind to specs claiming it should have cut on all flutes by their measurements ( The new grind did cut well but I should not have had to pay.)
 
Tks guys, will go with a finishing reamer since I will not do this for many rifles. Was thinking of drilling first but was wondering if the reamer would be "pulled" crooked since a drill bit is never perfectly straight. The pilot would hold the nose in position but the body might not. For this reason I was leaning towards reaming the whole thing. So after looking for 308 reamers. Which one is the "standard" one. There is like 8-10 different style?

For machining experience, I'm good to go. For actual practice, I wanted to set back a take off bull barrel I have. If I didn't want to do this and wanted to make a chamber from scratch on a piece of steel. Would it be better to take hot or cold rolled shaft or 1045, 4041 or stainless steel like 316SS. All of them we have in stock in the shop. I definitely do not want to dull my reamer on the wrong stuff before I want to do it on a new barrel. Not sure why so many guys actually say they re-barrel their rifle but nobody want a "spectator" overlooking :) It's all good. That's why I did watch a lot of youtube videos but would of been nice to be there live for one. So after all this, I decided to go ahead and try it out. Worst that can happen is that I learn something to do, or not to do again. :) Tks again
 
If you want to cut a very accurate chamber set the barrel up in the headstock of the lathe where you can dial each end of the barrel in with indicators. The muzzle of the barrel should be dialed in within a couple of thou... the chamber end of the barrel should be dialed in to the closest 10 thou of an inch... if the barrel is not really straight then dial just ahead of the throat area to the the closest 10 thou of an inch. Then bore the chamber undersize and ream to finish. Thread and fit while it is in this set up.
 
You can rent reamers from several places Stateside with no border fuss. reamerrentals.com is one. Add the W's.
Same guys will rent the set of headspace gauges you'll need too. A 'Go' isn't enough.

Egad do you ever check the accuracy of or responses to your posts? THERE IS NO US BUSINESS THAT RENTS REAMERS TO CANADIANS.

From the site you mention
"1. We ship to the Unites States only. We are unable to ship internationally.
2. A credit card (Visa/Mastercard ONLY) is required to order with us. We do not accept checks, money orders, American Express or Discover"
 
Its amazing how many times his erroneous information must be corrected by members , if it weren't for that he'd be on my ignore list.
