Unnecessary to go with this caliber in the TC platrorm unless you really want this round. I can't imagine an extra tenth inch of case length making a big difference. .357 Max barrels can be had lightly used for $200 or less. Quote HistoryQuoted:

MGM is listing 350 Legend barrels now. Available to ship in April if you have a contender or encore. $510 after I spec'd it out (16", threaded with pic rail). |

A 350 legend AR barrel should cost no more than the equivalent 9mm AR barrel. Give it some time and prices will come down.

Semi's appreciate rimless. Single shots like rims just fine. No need of a TC barrel unless you already are invested in the caliber. $500, damn prices have gone up. I had them do a custom wildcat for me a few years ago for $225 iirc.

GunBroker usually has a good selection. Any of the oddball stuff is usually pretty cheap. Mike Bellm will rechamber a 357 to Max for $90, so that's another option. I guess I was just thinking of the availability of a wide variety of factory ammo with the new cartridge. I had thought about getting a Max and shooting 38/357 loaded with ultra heavies, but I hear they don't like that much. Quote HistoryQuoted:

Thank God CMMG decided to thread the barrels in a "normal" thread and not 1/2-32 or 1/2-36 9mm threads. Makes getting or modifying existing muzzle devices much easier.
I'll just need another Griffin Minimalist taper mount brake for 5.56 in 1/2-28 and bore it out for 9mm like I did with my first AR-9 pistol. Not sure if their 1/2-28 9mm Hammer Comp taper mount would fit in my Form 1 can's blast baffle, but that would be even easier. Their barrel is even nitrided 
For $200, I'm in on the first batch. |

With the subs being a 75-100 yard round max, 1:16 may provide enough stability. I played around with Bergers twist stability calculator using 1.2-1.35 as reasonable mix/max length bookends, they all qualified as "marginal stability" but not "unstable". So maybe it will be fine. I agree 1:12 would be better, or at least 1:14 - maybe I'll wait for X-Caliber to have 350 Legend as an option so I can spec that on a custom barrel. UPDATE - I reached out to X-Caliber barrels and asked. They will be offering 350 Legend in their custom barrel configurator, they will be offering both 1:10 (WINNAR!) and 1:16 twist, and expect to have it available within about a month. |

FYI - X-Caliber has added 350 Legend to their custom AR barrel ordering page.
I'm holding off to determine optimum short barrel length for super and subsonic loads with common powders and accompanying ideal gas system length - might do some reading over on the MDWS forums to see how they faired with the 357AR. Unless @MDWS wants to chime in and make it easy? |

Aerodynamic stability at range is not what determines what happens a few inches from the muzzle. Excessive spin is probably more likely to create a baffle strike than inadequate twist rate. Quote HistoryQuoted:

Well X-Caliber made the gas system length discussion easy - they are only offering the 1:10 twist barrel in pistol-length gas and have the caveat that the 350 Legend requires an adjustable gas block
.
X-Caliber stated they don't have any ammo for testing, so they are currently sizing the gas port large enough that it is 100% certain to function with subsonic loads (my read: overgassed) and you'll have to tune from there with the usual methods. According to their customer service - they don't disclose gas port size. It's mostly a moot point anyways - my Quickload subsonic 350 Legend models I made up last night (using the 275gr Woodleigh Weldcore bullet as a stand-in) indicated that pistol gas was going to be required for any of the short barrels (10.3" - 12.5") to satisfy my back-of-napkin requirements of at least 12ksi at the gas port and 2-4ksi at the muzzle. Like 300BO, designing a gas system to reliably function subsonic/unsuppressed is guaranteed to be overgassed when running supersonic/suppressed. |
