Rookie reloader here. Marlin 336. Lee Challenger press and deluxe rifle die set w/ factory crimp. Bullets- Speer 110 gr. hollow points. This is the second time I've reloaded these cases using the collet neck sizer. First time I've used these bullets. I have to use quite a bit of pressure on the lever to close the last half inch. After firing, the empty case chambers easily. Any idea on what's wrong? Do I need to buy a Winchester? :shock: :wink: I'm using the neck sizer because it's supposed to give better accuracy with the fire formed cases. Also when I used the full sizer the neck was so loose I could seat the bullets by hand. I'm wondering if I didn't lube the inside of the case enough when full length sizing. Any suggestions would be greatly appreciated.
