Just got my new Grendel put together.. Over the counter ammo recommendations?

[Eldonkey]

Hi Folks,

Fairly new here.. Got my upper and lower put together, and am exited to get out to the range to see what this bad boy can do. With that being said, what ammo would you recommend for

1. Paper punching inexpensive fun?
2. Hunting Deer and/or coyotes?

Thanks

Frank
