Range time today

They can be cleaned in an ultrasonic cleaner.

pulled out the Sandman K and looked at it under a real strong light and ran a couple long stemmed Q tips down it

Was a little dirty but not bad at all, has about 14 subsonic rds and a little more than 500 factory supersonic cartridges thru her, the BCG was actually dirtier than the silencer

Did you clock them? If the point of impact moves, does the velocity stay consistent without and with suppressor?

Have you seen Garmin’s new chronograph? Debating if it’s worth the price since I don’t reload

Today's range trip was a bust. Since I have 300 or so sierra 135gr varminters I loaded 50 of them, 30 with 110 and 20 with 4227. It seems my ar doesn't like the nose profile, they wouldn't feed. One went into battery on the second attempt but I ejected it and it'd shortened by about .20. Good thing I didn't pull the trigger.

I guess you've checked your mag follower to be sure it's not sticking with the nose low.

I did not. I had a mag full of the 110gr vmax, fired 3 and topped it off with the sierra 135grs, so I don't think that was the problem? They were clearing the front of the mag and catching on the lugs.

Looks like the 556 mags are the problem, tried pmag 300 ones and they feed nicely.

They are fun with a can, they are downright giggle inducing with a can and giggle switch. They do make a gun dirty. Back pressure pushes the gasses back into the action a lot more than without.

light supersonic normally work in 556 mags, heavy subs have a history of going nose down in 556 mags

The 135gr sierra varminters fed flawlessly and I was getting 2.5 to 3moa, not bad for a 2moa red dot.
Sighted in the green laser on the g17, that's like cheating, it's so easy to hit with. A very satisfying day!
