I have a Lee hand held primer and decided to start loading for my AR 15. I have been using it for loading my .308 with winchester large primers and it works great. Well, I bought the #4 shell holder for it and put in the small pin and primer holder and the darn thing will not let me get the primers in correctly. The go in crooked etc. I decided to get the directions out and started reading. Heaven forbid. But as I read it listed the primers and it did not list the winchester small rifle. It listed the winchester large rifle, cci and winchester pistol etc. It also said not to use Federal at all which is interesting. Has anyone use this device for winchester small primers? I guess I will have to buy another primer for my winchester small primers. Any recommendations for my winchester small primers. I just bought the winchester primers so I would like to use them. Any info would be greatly appreciate. Thanks
