Any Canadian makers manufacture a 1/8" twist .308 cal. barrel? I'm not fussy wether it's chrome moly or stainless steel. Ideally, it would be a standard Remington varmint contour or slightly larger. If so, then who?

If not, then who imports them on a regular basis? I'm not biased on brand names as long as it's a quality barrel.

I'm building a .300 BLK (aka: .300 Whisper) and plan to shoot mainly subsonic handloads using cast lead bullets.

I can get them, you just have to pay an additional $35 for a non-standard twist.

Ian, I was just on your site and checked out Pac-Nor's site. When will that line be available to you and when will the prices go on your site?

McGowan makes them. I have one waiting for a similar project to yours but haven't managed to get the thing built yet.

Cool. Do you have it now? How long did it take you to get it? I've heard they have had a reputation for being exceptionally slow. Where they are in Montana, did you bring one in on ATR's import permit or did you go through the process yourself?

Have you bought a reamer yet or are you doing to use the .300/.221 one you already have?

BTW, I noticed on one of your pics in the thread on the "Black Rifle Forum". Looked like you were shooting either a 150 or 170 .30-30 FP cast lead bullet. How's that been working out for you accuracy wise? Will you be considering that combination in your bolt gun project?

His was part of a large number of McGowan barrels we imported and will be bringing in more as needed. From order placement to delivery was about 3 months.
We have the reamer and have built quite a number of .300/.221s.
We also stock the dies for it.

We have the new 300 BLK reamer to ensure that chambers will accept factory loaded ammunition now that Remington has SAAMI certified this cartridge. Older reamers may not be compatible with the new standard.

Those were 170gr cast bullets. They aren't the best in an AR cause they don't feed so well. I am saving them for the upcoming bolt guns we are planning.

The nice thing about cast lead is that it is safe in longer barrels without the need for further lubrication.

I take it you plan on keeping your bolt gun's barrel length to the 18.5" minimum to keep it non-restricted?

I agree regarding the use of cast lead bullets. It's likely all I will use once I get a load dialed in to my liking. The economy of reloading this round has a great amount of appeal to me.

Thinking several projects ahead, I can see a short throated .358 Winchester eventually taking space in my collection. While anything but a "precsion rifle", it should prove to be fun none the less.

I'm planning a bolt gun whisper project. Being a bolt gun, barrel length is irrelevant. Overall length becomes an issue if using folding stocks (eg AICS 2.0).

That is factually incorrect. It does INDEED become an issue if the barrel length is less than 18.0" on a manually repeating or single shot centerfire rifle.

Any shorter than 18.0" and you'll be heading to the "Prohibited Zone".

Definition of a Prohibited Firearm
The Criminal Code states that a prohibited firearm is:

•a handgun with a barrel length of 105 mm or less;
•a handgun designed or adapted to discharge 25 or 32 calibre ammunition;
•a rifle or shotgun that has been altered to make it less than 660 mm (26 inches) in overall length;
•a rifle or shotgun that has been altered to make the barrel length less than 457 mm (18 inches) where the overall firearm length is 660 mm (26 inches) or more;
•an automatic firearm and a converted automatic firearm;
•any firearm prescribed as prohibited.
 
I thought we were talking about fabricating a barrel from a blank. You are correct if you are discussing shortening an existing barrel.

I'm going with a new blank, and can therefore get the barrel to about 16" before the overall length gets to about 26". Mine will still be non-restricted with a 16" barrel.

If that's the case, I am mistaken. A shorter barrel is never a bad thing.
 
Maybe I am missing something but I never thought of cast lead bullets and precision rifles being one in the same.

The cartridge itself is reportedly very accurate. How I intend to use it is a different matter. BTW, a person can achieve exceptional accuracy with cast bullets.

There's a lot of interest today in building duplicate rifles with one being used as a trainer. In a lot of instances, we're talking .22RF. However, a full scale rifle using cartridges such as .300 BLK using cast lead bullets has a lot of merit.
 
Big bullets stuffed into little cases make me giggle :)

Shilen and Mcgowen 8 twist 30cal barrels available.

Whatever length or contour makes you giggle.

Cast bullets are being shot with amazing accuracy BUT that is big work. Casting bullets is truly an art all its own.

If you have the ambition and manhours, I have a custom 30cal spitzer mold that you might have lots of fun with.

Gas checked sized properly for WW alloy.

Fun, fun, fun..
