I just bought a Timney 510 trigger and installed it in my remington 700 sps tactical .308 and everything went smooth as could be at first. After the install I cycled the bolt and pulled the trigger to make sure everything was working properly and it was. Then after about 10 times cycling the bolt it started to seize up when I tried to cycle the bolt back. When you go to pull the bolt handle up to bring it back I have to use an extreme amount of strength to get it to move. I disassembled the bolt and nothing was out of the ordinary or anything like that so I put the bolt back together and then tried to cycle it a few times and it worked for a minute and then all of sudden it got extremely hard to pull open. I have no idea what is causing this. If there is anyone that has any advice that would be helpful.
