Guys I have a Stevens 308 action I just removed the factory sporter from. I bought a used heavy 308 barrel and was ready to begain my first barrel swap. I started screwing the heavy barrel into the action by hand and got about 1/4 of threads into action and then it stopped. I can no longer screw barrel into action by hand. Is something wrong or does this take a little force? Any thought or tip to get be started will be very helpful.

Thanks
