Extractor Damage or Case Head Swipe
Hi Guys and Gals.
I have owned a tikka t3 varmint in .308 for 2 years now and I fired 22 rouns through it in a competition last sunday. It began to rain halfway through my comp, and since I was doing pretty well, I decided to continue with my full shoot. Now..before anyone calls me a *** I am ex army and have been rained on a million times which has turned me into a fair weather shooter. This being said, it was the first time I have ever shot this rifle in the rain. Upon returning home, I noticed a scorch mark on my bolt face which led me to check my empty brass. Out of the 22, 7 were dented on the case rim (flat mark from ejector?) and one had primer blow out, which I presume caused the scorch mark. Luckily enough this has cleaned away without any pitting with some 0000 wire wool and cleaning solvent and I am asking you guys, do you think that this could have damaged my rifle? Is the rain the likely cause? Seems a little bit too much of a coincedence otherwise. I did check 100s of my other empty brass cases at home and they are all clear of marks.
I have read various articles about the cases basically being lubricated by the rain water and thus not gripping the chamber walls as they should. Please bear in mind that this weapon has shot flawlessly, and accuracy want effected at the time. As i mention I only noticed when cleaning my rifle.
Any help or advice would be greatly appreciated.
