Thanks greydog.
Most people here have far more experience with firearms than me. I’m not aware of everyone’s careers , or experience so occasionally I offend with my limited input. No intent to offend, just unaware of others knowledge and experience. That’s why I ask even simple questions that the average shooter may know. I’m willing to listen even to rookies. Sometimes great ideas come from the youngest…..
I’ve never heard of doing pillars as you describe, however I can see the merit in the idea. Might be a good alternative.
