Howdy from Sacramento area!

I'm really excited to pick up my first bolt gun on Friday. Given the wide variety of 223 cartridges available ( bullet weights, velocities, manufacturers, etc.), I was hoping folks on this forum with fcp-k 223 experience could share some of their factory load recommendations and maybe save me from buying one box of everything to try out. I am expecting I will need to find the rounds my particular rifle "likes", I'd just like to narrow the field of possible cartridges if I can.

I plan on a 200 yd zero and shooting 200 - 400 +yds, primarily at paper and ground squirrels.

Any tips or advice on factory 223 ammo would be greatly appreciated.

I don't reload right now....

Thanks for looking and in advance for sharing.
