Season three episode 21 the twilight zone called kick the can . Anyway it is a tool and thank competition for making it affordable for most of us that want one .
You need a bore scope.
this is how fake news gets shared all over the net. You read or heard about this or that.
I started shooting competitively in 1968, and stated shooting p. dogs in the late 70's, rock chucks, jack rabbits, and ground squirrels. I went through many, many thousands of rounds a year. I have had access to a bore scope since the late 80's. My p. dog hunting partner and I used to order 10 Hart barrels at a time.
I have looked down the bore of a few tikka's and they can not hold a candle to the quality of a Brux, Lilja, Krieger, Hart, Shilen, Bartline, etc.
If you are serious about your accuracy, buy a bore scope, clean your barrel, measure the over all length of the bullet to the lands, frequently and maintain that distance as the leade grows. Chronograph the most accurate load tested, and over time when the bore wears, you will have to add a few tenths more powder to bring up the pressure to where it once was.
Exactly my argument.Am I the only one who knows each barrel has a shot limit before being replaced? A cold bore shot, is different than a hot shot, no matter, every 100-250 rounds clean out the carbon & copper, check zero, & soldier on!
I started to get flyers that I didn't normally have.
The carbon ring was giving me a false CBTO measurement. Once I cleaned the carbon ring out, I found that my true CBTO measurement showed me that I had lost .025" of my lands.
Once I readjusted to my original .024" off the lands, the flyers went away and started shooting tight groups again.
