As I was shooting today, I noticed as I worked up in my load that this rifle was swallowing everything with no problems. Then when I hit my final group shoot, I stepped up another half grain ( 7mm-08-- 140gr. sierra spitz. with H4350 48grains.) After the first shot I broke down the action and the case stuck in the chamber. I worked it a couple times and nothing. I ended up using my cleaning rod to push it out. No problem. Well I shot the second and it ejected fine. I went on and shot 4 more and all ejected nicely. I shot a total of 6 shots with this load. After putting my rifle away I went to inspect my brass. Upon inspection I noticed that the last 6 shots talked about above had that burnished spot or light scratched spot on the case head. I know in my bolt actions that this would be a sign of to much pressure and need to back down. I am wanting to know is this sign the same in a single shot? By the way that was the max load listed in the manuals for that powder/bullet combination from the 7mm-08.
Last question, could this have damaged anything? My barrel, chamber etc.??? I seen none . When something like this does call damage, is it something you will know when it has happened? I mean you won't shoot for year with a stress crack in barrel or chamber and then gun blow up one day will you? thanks for the help.
