[QUOTE="Blackhawk, post: 1995228, member: 105459"] [I]I encountered the same problem with my new .300 Winchester Magnum Rifle and cartridge. I wanted to get to the range early and spend the day in load development, but alas that was not to be. I used my match die without the busing and FL resized my brass annealed it (these were virgin cases), then on to check COAL. length and fl resize again this time with bushing inserted I also adjusted the die to give me the-.002" shoulder bump. Now my new brass fit my chamber and my COL gage and was good to go. However, the lot of twenty-five cases that I thought were Fl resized and ready to load well this is what happened. Imagine my surprise when I could not even insert one case into the COL gage. This brass was from an older lot and I wanted to use them as well. My bad I didn't check the cases to make certain that they would fit into the chamber of my rifle. It was only twenty - five rounds that were loaded and earmarked for load development. Needless to say, I got out my trusty RCBs bullet puller with the correct caliber collet and broke down all twenty-five rounds I dumped the powder back into the powder hopper. After getting my brass Fl resized again with the match die set inclusive of the bushing. This time I brought out my Redding .300 Win Mag Body die as well as the #6 competition shell holder set. Starting with the .010" shell holder and working down to.-006' MY CASES FIT LIKE A GLOVE TO MY RIFLE'S CHAMBER. IN RETROSPECT I NOW BELIEVE THAT I ONLY USED A NECK SIZE DIE DIE ON THESE OLDER HULLS, HENCE THE PROBLEM. [COLOR=rgb(97, 189, 109)][B]I THINK THAT A REDDING BODY DIE AND COMPETITION SHELL HOLDER SET(CALIBER SPECIFIC) MAY BE A GOOD CHOICE FOR FUTURE PURCHASES.[/B][/COLOR] [COLOR=rgb(184, 49, 47)][B] With that said please do not rely on just a case gage..[/B][/COLOR] They are made generally to Sammi spec and your chamber's dimensions may have a slight dimensional stacking and still be within tolerances. Remember everything manufactured has tolerance and your rifles chamber is no different. So if I were you here's what I would do. If your rifles bolt closes home smoothly and easily without forcing your bolt into battery, well then you are now golden and good to go! [B]Enjoy your range day !!![/B][/I] [/QUOTE]
