[QUOTE="DrBaker, post: 718395, member: 50"] My personal experience has shown me that a 1:7 twist is good, including my SBR testing. I shoot from 55-77gr in 5.56 and this has always worked in every 1:7 twist barrel I have used. The most common complaint I hear about the 1:7 twist is that it won't work with 55gr. I guess somebody somewhere might have problems with it, but I can't count the number of times I've successfully ran the combo. Never a problem with it. On a side note- I've had a few 1:9 twist barrels that would stabilize 75gr. Not every one of them, but it can happen. My personal choice after trying several bullet weights, twist rates, and barrel lengths is the 1:7. [/QUOTE]
