Practice.. perhaps I should have asked the question differently. I read this forum every day and have received help with more than one subject,(thanks DR. Drew, Ellenbr.) just didn't recall anything about EXCESSIVE heat. Took the advice from this board and coated the heads of all my stocks, and shoot RST shells in all my old guns. I guess I could take an auto-loading splattermatic and not worry about anything. This opener I have an opportunity to hunt a private dove field, and if the birds come in fast and furious, I was worried about damaging a gun that was given to me by my now deceased Uncle. As a dog owner, I have a responsibility to them to hit what is pointed and flushed. I guess A double on wild quail and phez. last year, a few limits of woodcock before 10:00am, 22 clay birds is not good enough, in Arizona land. I detest bragging, but I would be proud to take any of the young people or dogs I have worked with, and hunt or shoot with anybody anywhere...just a thought
