HI I bought some TUL 308 ammo and when I shoot it in my Encore it will not fire the first time I pull the trigger,, I have to recock it then it will fire.all the time. but never on the first trigger pull.. American ammo and my reloads all work on the first trigger pull. Is that a normal problem with cheap TUL ammo steel cases.. it is accurate and I bought it as an emergency stash. should I replace the hammer spring in my Encore or find a cheap 308 rifle (Miltary) ? it seems to be well sealed and would be good for long storage... what say you all ?
