I have a LH 110 in 30-06. Fired 3 rounds this afternoon and bolt was unusually hard to open and close. Shooting 150 gr hornady superformance, which I have shot probably 20 rounds of in the past. Now the bolt won't close completely. I had purchased a new bolt handle, but wound up putting the original back on. Installed a Tinney severals years ago and everything has worked fine. What could be causing this? Any help is greatly appreciated as I'm new to this.
