350 Legend SBR – How I’m loading It – Testing NOE 183 GC “Taco’s”? – Explosive Results!!!?
The 350 Legend Eats Taco’s!
If y’all haven’t seen the unlimited humor of Uncle Jim on his channel, you’re defiantly missing out. Well, he sent a huge assortment of bullets to feed this SBR. In this test I’m going to see how well an NOE 360-183 GC bullet feeds and shoots.
The Rifle Build…
SBA3 Buffer Tube and Pistol Brace
Spikes Tactical H3 Buffer
Strike Industries Flat Carbine Buffer Spring
Davidson Defense branded (Aero Precision) Upper and Handguard. Slick sided
UTG Recon Flex MLok Bipod 8-11.5”
Unknown Ebay 5/8×24 30 cal Muzzle brake reamed to 45 cal
BCA 10.5” 9mm Closeout Barrel, Re-contoured after Gas Block to reduce weight. Muzzle threads cut and re-threaded to 5/8×24. Gas Block alignment dimpled using KAK industries dimpling tool. Barrel Extension replaced to M4 Style feed ramp
Carbine Length Gas Tub and Aero Precision Non Adjustable Gas Block. Gas port size (Secret)
Mag Mods To Make it Feed…
This is nothing new as many made an AR15 feed a similiar cartridge to this “NEW” 350 Legend. Using various post on 357 Max AR rimless builds, I came across a detailed write-up on modifying magpul mags to accept a straight wall cartridge.
Since Magpul Mag’s are made of injection molded Polymer it makes quick work using a Dremel and files. I used a 10 round Gen 3. The first thing needed is to remove the shoulder guides
These Taco bullets are a FP design. This causes issues for semis and feed ramps. A slight grind and polish was done to the M4 feed ramp. And I changed the Magpul Mag spring to a 30 Round spring in my 10 round mag. This is to increase the follower pressure, further explained in the video below.
Flat Point Bullets Expand?!?…
No secret here as seen on the video thumbnail. These Taco Bullet’s expanded like an XTP bullet yet they deliver mass amounts of energy down range. Really surprised me how well it stayed intact. Can these be a viable hunting round?
