I noticed these Heym rifle barrels available through Numrich about a month or so ago.
I was going to order a few then but sometimes need to wait a while and see if it makes sense a week or so later instead of ordering and not needing anything but buying because of the low price.
When they first listed them there were 4 pages of them and now it's down to 3 so they are selling. At first they had some cool odd ball calibers like 470 NE and 500 NE. but they are gone now. They still have several in 9.3 cal. one is chambered for 9.3 X 62 and one that is unchambered.
Heym is a high end gunmaker so I assume these would be hi quality barrels and they have them in both bolt action types with large diameter barrel shanks that could be rethreaded for other bolt guns and chambered and unchambered blanks for projects that can used as a liner or for what ever you can use them for.
I ended up ordering 2 blanks that were tapered for a SXS double rifle and were turned to .43 OD from a little ways past the chamber swell. They are to thin to use as a barrel for most rifles but I thought they may work as a liner in a 410 as they are real close to the right diameter already and would save me HOURS of turning a larger blank or take off barrel plus the bore should be more stable to stay at the proper size compared to turning a blank down that thin and having the bore open up.
Currently Numrich is offering free shipping on orders over $ 75 but on barrel blanks it cost you $ 1.00 shipping each because of the size or length they always get you for a extra buck on barrels.
So if your in the market for a barrel for a project take a look at these while they have them as I have found many times before that if you put off buying say for a year or 6 months they will be gone. I know it has happened to me many times with Green Mountain barrels, several years ago they had blanks listed in all sorts of calibers and hard to find styles and I thought they would have them forever and found out different.
Sorry I don't have a link to the website, Go to Numrich, search rifle barrels, click on barrel blanks.
