Hi all, I just got a PSA upper in 300 BO, 16" pistol length gas tube. I have been making my own brass using Lee dies and checking with a Wilson gauge for fit and length. All seems fine, Then I load a few rounds using 10.5 gr. of 1680 and the NOE 311247 cast boolit -powder coated. When I try to chamber them, they are hard to go into battery and if they do they are very hard to eject (unfired). THen I bought Hornady 220 gr RN Jacketed to see if they worked better, did not.
I did buy some Remington 300 BO 120 gr. and they chamber and hand eject fine. I suspect that they are not sized enough. Is there a sizing die that is smaller than the Lee that I have? I thought that I would try one of the rounds that I did fire and see if fire forming would help, but it did not.
Also I would like to know what the COAL is for this NOE boolit.
Any help is appreciated for this OLD FART
Thanks
Tim
