Will any of the bigger ones fit in the chamber for the smaller ones ?

Edit. It appears not but not looking for a 300blk/556 situation

Somebody went the long way around to create the 30TC?

What have we done to you sir?

 

[anon]

A .308 wont fit in a 6.5 Creedmoor, a 6.5 Creedmoor won't fit in a 6XC, a 6XC won't fit in a 22GT, just sayin.

LFD Research Films the Firing of .300 Blackout in a .223/5.56 Chamber -

LFD Research simulated a catastrophic failure by chambering a .300 Blackout round into 5.56 AR-15 and filming it in slow motion.

As someone that has all 6 mentioned in the Op rolling around on my dash

I can only see positive results with 7.62 expanding in length through the 556 barrel. I only see gains in BC from fireforming a 175 SMK .308 bullet in a 224 barrel

Shhhhh! You're going to ruin my secret for the next PRS season (running a 30TC in a .243 chamber and .237/.243 barrel). By the time it exits, your typical 168 SMK has a G7 BC of over .5 with virtually no recoil.

Just make sure you video your fireforming results, and post it on YouTube.
