Cats, Guns, and more. What’s not to love?
Since the scope was still out and I’d never looked inside the AR-10 barrel:
Clearly some carbon fouling down next to the lands and a bit of copper on them.
Ramps to the lands are dirty but not much in the way of erosion.
Lots of carbon at the mouth and inside the chamber. Not surprising with a direct impingement gas system.
Gas port is clear, maybe a little wear or buildup on the left.
Time for some Wipe-Out!
The “After” pictures. Remember, if you see blue, it means copper fouling.
Shiny clean lands:
End of chamber, ramping up to lands. Not much throat erosion.
And crown at end of barrel:
3,000 plus rounds. Wipeout for the win.
At a certain age the doc wants to check things under the hood. Well, more like via the tailpipe. Since I’m scheduled for one soon, it got me thinking about scopes. In this case, a borescope.
I hadn’t scoped the 6.5 in a while, so I fired up my Teslong bore scope. No, not Tesla, and if anyone keys any of my stuff . . .
Anyway, I did a quick bore clean so the scope could get a good look. First thing I noticed – lots of copper on the lands. A little copper smooths out imperfections in the rifling, but too much is counterproductive.
Next, check the throat for erosion. Not much at all. What you’re seeing is the end of the chamber, the leade, and the ramping up to the rifling.
Here’s the crown at the end of the barrel:
And the blowout hole in the chamber wall:
So, best tool for the job:
WIPEOUT!!! (The Surfaris?) With Wipeout, you spray the stuff down the barrel and up the breech. It immediately foams out everywhere, which explains the paper towels.
I’m going to let it soak overnight and then do another rifleoscopy. With before and after pix, of course.
Do you know your point of impact shift from cold barrel to warm to suppressed?
Despite the best efforts of some ne’r do wells, the upper range opened today – I was the first to go up.
I did 6.5 CM and .308 Win. Lot of crosswind and difficult lone spotting, with damp berms. Still, got the 6.5 out to 533 and the .308 out to 750. No time to send the drone dowrange to spot for me. Tomorrow.
Lube, size/shoulder setback, deprime:

I should do a contest – “Guess the number of primers and win a free subscription!”.
Yesterday at the range, shooting to compare from five years ago:
Center – fouling and sighters, plus one round with damaged meplat Still, .763”.
Upper left – Hornady 140 ELD Match. Cases sorted and bullets weighed. .459”.
Upper right – Nosler Competition 140 HPBT. .281”. Yes, that is three shots.
Lower left – Hornadys, again, but unsorted brass and loaded ages ago. The flyer puts it at 1.033”, but .226” without.
Lower right – My last two Hornady 140 SSTs from the bullet shortage during the Plandemic; they were all I could find at the time. .742”.
I think I’m going to write to Ruger to tell them that this 5 year old rifle, with over 3,000 rounds through it, still shoots well.
As I was falling asleep last night, I was trying to remember all of the upgrades I did to the rifle. Of course, I bedded it. Then, I
Let’s see about photos during this process:
Then I went to Texas with some shooting buddies/budettes.
I was the only one to engage the 750 target out next to the big tree. First shot left edge. Adjust. 3 good ones. A buddy knew I could shoot ok, but didn’t know how much. He brought back this pic:
I went out today to see if my 5 year old rifle with over 3000 rounds through it was still functioning. I’ll show you tomorrow.
