Never seen Federal 210. I use 209's for my .35 Remington. Sorry no help.

The I at the end means they were intended for international sale.

 

I think deaddeerwalking is right.

 

Hey Thanks DDW. I was wondering if the I stood for international. I looked under international on the Federal Website, but they didn’t show anything.

 

I’ll take them. PM incoming!

😊Took me a good 3 months to find some, but when I did, the guy was selling 1500 of them. It was an old fella getting out of reloading, and I couldn’t hand over the cash fast enough.

 

Choot'em.

 

My primer of choice for the last 4+ decades, #210 for large rifle, and #155 for magnum large pistol. None better. Still have some in storage, I haven't had to buy primers at 2022 prices. Dreading that day.

Odd, I have to load the F209s in my shotshells, they’re too long to fit in my .35 Remington cases….

I just picked these up on a local sale. I didn’t notice the # on the box until I got home. Has anyone seen this Federal # before? Can’t find it anywhere online or on The Federal website. Everything online is just the #210. Size wise, they look just like any other large rifle primer. Thanks. View attachment 878789

My guess is Fed 2101 is foreign. I suggest to contact Federal and ask them either by email or phone. My guess is they're Fed. 210 or 210M

PS I thought the I was a 1.
