Hello,

Wondering if anyone has experience with this combo (Sierra SKU 2121). I have some Lil Gun on order and was going to start there.

Yup. 18.5grains Lil gun under 125g is my secret combo. same hole at 100yds . If I remember correctly it around 2500fps, yes really. it's a 16" barrel I use that one on. no pressure problems. Sig brass.

Sweet. I'll try that from my 9" PWS.

What do you want the bullet to do on impact? Matchkings, even though they're a 'hollow point', are not going to expand. They're made for poking holes in paper and bad guy's noggins.
Tipped Gamekings or Pro Hunter's, on the other hand, would be a better choice if you want expansion and energy transfer.

At this point I would just like to punch holes in paper. Or ideally all of them going through the same hole.

I'd start at 18gr and ladder up through there. Your barrel is going to have a say in it too. if you're running a CHF chrome lined barrel you'll probably have a better window where it's going to be most accurate. Profile depending probably even more. . Daniel Defense or Criterion have been the best in 300BLK in my observation. Faxon would be at the next tier down for accuracy, they're just not CHF. But still quality.
But that's just one opinion from my observations from a random guy on the internet.. YMMV
