That's all I have here, no issues.
When you first cap them, the feel loose and are real easy to twist off but after the pressure builds a bit, you almost need a glove to twist em off. Hasn't hurt my capper as far as I can tell.
As for the twist offs its all good if you use a bench capper. Just becareful. I have been cut very bad holding a thin twist off bottle that explodes in my hand while capping. I now where 1 leather glove [Mike Jackson style], and only use heaveyer returnables.
