  Now you give me Heartburn of a different sort....way past age 70 thinking I knew it all "YOU ": come along and start teaching me things I never knew. Keep it up , I and my Saturday morning Breakfast Pals  love discussing the new things we learned  this week...Thanks from Central Texas

  Hi Josh, Great video. I just put a new barrel on my Walther KK 500. To me it seems like you had to dance with 3 numbers for the install. 1. Head space 2. Shoulder depth and 3. Bolt face to barrel face clearance. I spent the time to understand what those numbers were before i removed the old barrel. This proved to be very helpful.<br> &nbsp;Thanks my friend for your videos.

  It seems like maybe the second five in the mag shot better than the first five?<br>I’d love to see this excellent trial repeated using five shot magazines.<br>Thanks for doing this experiment.<br>Regards<br>Robert<br>( just bought a CZ 575 😊)

  Strictly speaking the first two groups shot with the 0.045 heads pace was at an advantage to the others in that you fired a group to warm the barrel then immediately proceeded with those two groups. When you changed the headspace the barrel cooled but it appeared you went straight into the groups without warming the barrel again. I would also do this testing from some sort of jig / clamp to take human error out of the equation. Another aspect to try would be to measure the headspace on the rounds and sort them into different groups and then shoot groups with the same measured headspace. From my experience even Tenex has varying headspace measurements. Thoroughly enjoy your video&apos;s. Keep up the great content.

  Fiy. I used a 18 inch lothar barrel on mine didn&apos;t have the shim option but it shoots incredibly good. Great video. Impressed by your content.

  Thank you. &nbsp;I wish you had the crono on so we could watch sd and es numbers for a more detailed study.

  You are becoming my favorite quick. I like my CZs but we only have sporter style gun matches where I’m at.
