Topics discussed in this episode:

Intro [00:00:00 - 00:02:52]

Gain twist barrels, is there merit there? [00:02:52 - 00:09:04]

Your specifications say barrel within .0001”-.0002”, which is extremely consistent. Many people talk about 22lr barrels needing a ‘Choke’. With this consistency, are your barrels not choked and is it really required? [00:09:04 - 00:14:48]

Barrel length, short or long for accuracy, which is better? [00:18:11 - 00:21:55]

Why different powders product different results [00:21:55 - 00:23:03]

They say you need a straight barrel bore for accuracy, is it true? How straight is the bore? [00:23:03 - 00:25:25]

Is there such a thing as a hummer barrel as a hummer barrel? [00:25:25 - 00:25:25]

How as a manufacturer do you make your barrels shoot well enough to be competitive at the highest level? [00:43:13 - 00:46:02]

With modern barrels is there any point in choosing say a Varmint/bull barrel or standard barrel for long range shooting? [00:46:02 - 00:51:05]

I’m trying to find a good reload using solid copper bullets (such as barnes ttsx, nosler e-tip, etc) in a tikka with a 1 in a 11 twist. I’m seeing lots of articles suggesting that you don’t go by weight of the bullet, but rather the length. Why is that? And is that the true way to find a good bullet for a barrel? [00:51:05 - 00:57:10]

Why are you so GQ? [00:57:10 - 00:57:38]

For my hunting rig, with weight saving in mind, should I go with a pencil barrel or a canon fibre wrap of the same length? [00:57:38 - 01:00:12]

Does an 11 degree target crown make a difference over a 90 degree or other? [01:23:05 - 01:24:04]

Barrel or stock, which makes the most noticeable difference to accuracy? [01:24:04 - 01:24:51]
