New to the forum any advice would be greatly appreciated. Purchased a used venture in 7mm-08 for pa whitetail hunting this year. Gun was said to have 30 rds through it and I believe that is correct and I have since put 40 rds through. So the problem is I went out last night and had a nice doe at 20 yards and squeezed the trigger and click, did not fire. Tried 2 more rds and same thing. It then came in to about 10 ft and stood there as I desperately tried one rd 14 times and still did not fire. Ammo was Hornady American whitetail. I shot half the box a week ago and had no issues. All 3 had light primer strikes. Disassembled bolt and all looks good. Manually cocked it and pin sticks out where it should. Here's where I'm concerned. When dry firing the back of the firing pin seems to move at the right speed. When I tried to fire it on a spent case it seems to move very slow and sounds like it's not very powerful. I'm just not sure why when a round is in the chamber the firing pin power would be affected. Was hoping it was an ammo problem but not looking that way. Temps were right about 30 degrees. Any input would be appreciated.
