X'2 on Remington FTF. I run suppressed only in .22, and have also had a butt load of trouble with them. Are you running in a semi, or bolt? Let me know if they run good in your semi. I ordered 1000 and sent 800 back!
I have been running them in a Ruger 22/45 with a PacLite upper and a Ruger 10/22 with a Whistlepig barrel with a Thunderbeast 22-L suppressor on them and both have run flawlessly. I have had problems with Aguila and CCIs not firing in the pistol.
I have had lots of problems with FTFs with Remington bulk stuff too, not just in one or two guns, but any of dozens of .22 firearms I have shot it in over the years, both mine and other people's. At least one in ten is a complete dud in the last ones I bought, and the ones that do go off never seem to have the same amount of powder, make the same sound, or hit in the same place. I just went through a 550 pack of Fedral bulk with only 1 ftf total, and good accuracy and consistancy. Federal or Winchester have both worked well for me over the years with the bulk stuff, and I love CCI for the better stuff-never, ever, ever had a single ftf from CCI .22 ammo after shooting it for nearly forty years, but I'll never buy another Remington .22 shell if there's any other choice.
I run federal bulk pack ammo through my Ruger mark II with a PAC light and cci standard velocity through my cz452 and 10/22. Those seem to work best and stay subsonic with my silencerco sparrow attached.
You might have left a zero out of your math.......not 3 boxes=1500....it is 15,000 which is way more than 3 boxes.....like 30 bricks....I still don't think it will be on any list since ammo is not regulated in GA. In MA, you can only own a certain amount with a special permit issued by the state. I know you can't legally buy any bulk ammo in MA.
