Below is my less than favorable rimfire account, prompted by Buckshot's comment on the thread Molly started.
"I have read of a few incidents with centerfire rifles and factory ammunition having had various issues. Invariably the maker issues a UPS call tag and asks to have both the balance of the ammo and the firearm shipped to them. It seems that CCI's customer service dept simply took a pretty cavalier attitude."
I previously favored Remington bulk pack 22 hollowpoints, since local availability and price helped offset the rate the kids went through them. I regularly picked up another box when we got below a couple on hand.
Last year feeding issues and light strikes started occurring with several rifles and pistols, with various action types. All are domestic guns of good quality and none have match chambers. I wondered if dirty firearms might have been partly to blame so everything was thoroughly cleaned. No change. Next I tried some Federal bulk stuff and every gun functioned fine.
A micrometer revealed the problem. The Remington lead is knurled and diameter varied significantly between boxes (different lots). It was as large as .228 on quite a few samples from one box in particular.
I sent a detailed note to Remington explaining the issues with multiple guns, cleaning to eliminate other causes, the dimensions I found with one lot of their ammunition, and requested assistance. They replied to send the stuff in at my expense, marked as ORD(?), and they would look at it. That was it. There was no offer to pay shipping, no suggestion to dispose due to safety concerns, or much less replace the lot with oversize knurling.
Since the hassle and shipping expense exceeded the cost of new Federal, I set the remaining Remington aside. I will personally use it in a bolt action with a more generous chamber, so my kids don't have to clear jams and misfires.
I'm in manufacturing and understand tolerances. No heartburn from here if the manufacturer just takes responsibility. I also take gun safety seriously. With 2 to 3 kids on the line, regular misfires and feeding jams create an undue level of risk. Remington showed little interest in helping, so their 22 ammo is history for me.
Your experience may differ.
