Anyone load 300blk subs with flat base bullets?

[Snuby642]

Considering loading / buying some flat base subs for 300blk.
For some precision 100 yd work.
Need not necessarily be expanding.
1000 - 1050 fps max
1/7 twist 16 inch barrel.

Paper and head shots only.

I have Sierra 220 RN that I use. The bases are flat. For subs, I say don't spend a lot of money. Get the cheapest shit you can find

You already know what I do but I would like to play around with the new 220 ballistic tip that supposedly expands at subsonic speeds. This 220 Sierra bullet went into a does neck, facing me and it traveled along its entire backstrap to right before it pinched out. I couldn’t find an exit hole but in butchering the straps I found a hole running along the whole thing and recovered it right above the rear hips. It’s pretty much why I moved to supersonic for animals. For paper and headshots it shouldn’t be an issue but not every head shot goes according to plan.

Yeah subs don’t expand at all. One of these traveled thru 2 4x4s and then thru a wall and landed on the floor. The other went thru 1 4x4, hit the next 4x4 and bounced in the air

I've loaded some 265gr. cast/coated flat base bore riders.
