I need to replace my antique aluminum rifle cleaning rods and I'm wondering about the difference between carbon fiber and stainless steel. Does a carbon fiber .22 rifle rod flex more than stainless? What about retaining grit? I have modernized my pistol kit with Pro Shot, micro polished stainless rods and I like them very well! BTW I'm planning to get one piece rods. Thanks for any info or opinions you can send my way!
