20 vartarg improved?

[Dstaffk5]

Is there a 20 Vartarg improved with a 40 degree shoulder? Would it be just a 20 vartarg ai or is there another name? Thinking about building another 20 cal using Lapua 221 fireball brass.

I think one guy called it a 20 SCC

Can someone explain the difference between the 20 VT and 20 SCC? Can you post a picture? THANKS

So now that I have my 1000 pcs of formed 20VT brass, can you fireform to SCC? I like the fps factor!

Not sure if the 20-221AI Gabe22BR has been shooting is identical to the SCC but would assume if they’re not the same, they’re extremely close.

I have heard it called the 20 FBI - “FireBall Improved”

I think Gabe calls it the 20 FireBlaster. I'm sure if he sees this he will let us know the difference between all the variations. No matter how you slice it the 221 FB case necked to 20 is an awesome round.

Yes you can, just like any other AI cartridge.

Mine is a 20-221AI, no turn neck (20Fireblaster) JGS is the place
I have all the Reams’s for it, resize, & chamber to make my dies-
Newton silver, Wilson seater, or Newton micro seater, which ever.. I like Wilson best.
My OAL is 1.432” so brass has to be made, or keep the carbon ring scrubbed…I make my own brass, keep trimmed to .002”/ .003” short of max.. simple step there..
