350 Legend re-build with RT-3

[stagpanther]

What I plan on doing is developing a high velocity 9mm load (the legend really is a .355 cartridge IMO) to see what I can get from it.

Thinnest most prone to crushing brass I've ever used for a cartridge that size;

in over 700 rounds, I've never crushed a neck (much less a case.
But then... I've have never had any problem w/ 32-20 either.
Maybe same reason I've been married 53 years.

I just got back from testing some 115 gr 9mm test loads--I was able to achieve over 2900 fps and 2170 ftlbs KE at the muzzle while the group stayed together pretty well, and I believe I found a good node and will develop further. There's a discernible velocity point (2,850 +/-) when felt recoil kicks up a notch from softer recoil loads, but that's also when the groups tightened up noticeably.

I've never crushed a neck (much less a case.

You are a stud among studs. It's flimsy brass, no two ways about it.

So is the new Faxon Barrel GTG? I have the complete build ready sans the barrel.

My DI 10mm is churning along like a champ, so when I am done with that, time to turn to the Legend.

Yes, it works just fine.

Thanks!

Just make sure whatever you use doesn't potentially leave the top of the web of your case unsupported--that was the problem with the first legend barrel I bought. SAAMI specs have an exceedingly generous space allowance for the chamber IMO, and if the chamber is also radiused at the face that too can reduce the area of support.
