AR prices are hilarious right now. The best part is that the price drops have flowed through to AR parts so even if you're building from scratch with premium components, the prices are lower too.I wonder how low AR15 pattern rifles will get this Christmas?
I was under the impression that the Wylde chamber had the same length throat but a smaller diameter than 5.56 achieving better accuracy but still allowing the use of 5.56 ammo.There are actually 3 throat sizes, the SAMMI approved .223 Rem (shortest throat), .223 Wylde (mid-size throat) and 5.56mm NATO (longest throat) barrels. .223 Wylde is a compromise that has uses in match type competition since it is well suited for higher pressures with middle weight bullets. .223 Rem has a SAMMI max pressure of 53,000 psi due to its short throat and the fact that it was developed as a cartridge for varmint hunting, shooting light weight bullets. 5.56mm NATO is rated by NATO for 63,000 psi and the longer throat means it works with longer heavier bullets better than with light short bullets and handles higher pressures better.
In general you should not shoot 5.56mm NATO ammo in the .223 Rem barrels, but .223 Wylde can handle both .223 Rem and 5.56mm NATO ammo, although the longer heavier bullets work best in 5.56mm NATO barrels due to the longer throat. Still 5.56mm NATO barrels can fire both .223 Rem and 5.56mm NATO ammo.
In short, .223 Rem is best suited for 35-55 grain varmint bullets. .223 Wylde is best for match shooting with 55 grain bullets and if you intend to hunt deer, or anything requiring a 62 grain or a longer/heavier bullet you should be using a 5.56mm NATO barrel for best results.
That would be news to me. I understood it was simply between the .223 Rem and the 5.56mm NATO throats in length.I was under the impression that the Wylde chamber had the same length throat but a smaller diameter than 5.56 achieving better accuracy but still allowing the use of 5.56 ammo.
