I'm done with Remington .22 ammo. It is the dirtiest crap....a few months ago I shot through a brick of Thunderbolts and it was like getting tar out of my guns. Yesterday, I tried out ~100 rounds of bulk Golden Bullets through my T\C Silver Lynx...afterward the gun was a total mess, so bad I had to do a complete break down to get it right.
I'm "biting the bullet" on cost and sticking with higher quality bulk ammo like CCI Blazers
