New Varmint build, any guesses what it is?

22-6.56 wag

LOL I never even heard of that one.  I'll have to look that one up, but no that's not it either.

In preliminary testing this cartridge is shooting 55gr Bergers out of a 26in. barrel 4100fps and hadn't pressured out yet.  Shot 40gr Vmax over 4500fps and surprisingly the bullets didn't vaporize in flight.

20-08?

Ohhhhhh, that is reallllllllly close, but still not quite it.

Lol, I only shoot over the counter stuff, have never reloaded yet, and really don't know much about caliber development. Your building a wildcat right, So pretty much can build anything off another case as long as it isn't bigger then parent case?

17-08?

You had the right caliber the first time, just wrong parent case and shoulder angle.

Winner winner chicken dinner!!! 

The boys at Defensive Edge Rifles have been developing a 20 caliber version of their "Terminator" line and came up with what they are calling the 204 Terminator which is a 260 Rem necked down to .20 cal with the same shoulder angle as their other Terminators.

It's a given the barrel life probably won't be much over 600 rounds but shooting those 20 cal 55gr Bergers 4100fps and maybe more, should be a lot of fun and I can only imagine what it'll do to a coyote or groundhog.

Imagine what it could do with some 62 gr sierra's
