I was reloading 300WM bought once fired brass. I full resized the brass loaded IMR4831 73g win primers win brass and 180 sst. When fired the brass bites in chanber just above band.The gun does not do this with factory load. no pressure sign on primer. Have not had any problem like this with all my other guns but none are banded. According to my reload manual it said 74g is max load for this.Any thoughts would be helpful. thanks Jeff
brass sticking in chamber

+1 to that. In a bolt gun that is about the only reason for your brass to stick. Primers sometimes show signs, sometimes not. Try and find someone with a chrony to be able to work out actual velocities from the rounds you loaded. I think you will find them a tad hot....

+2 or whatever on you having found a load that is too hot for your rifle. If the rounds chambered fine there is no problem with your sizing. Throttle back on the powder charge a bit and try again.
I suspect the bolt was quite stiff to open?

I used to have that problem with my 300WM and any other belted calibers. What you need is a "Belted Magnum Collet Resizing Die" from Innovative Technologies, their website is 3w's dot larrywillis dot com. It removes that little bulge above the belt when you full length resize the case.

If you read his first post more closely,you will see that it is not a sizing problem.The sized rounds chamber properly,the problem occurs when the round is fired.And as his last post states,the problem disappeared when he reduced the powder charge.
As for the collet sizing die,I have loaded thousands of rounds of belted cases,and I have never found the need for one.
About the only advantage to be gained with neck sizing, vis-a-vis belted cases, is that you headspace off the shoulder, which is only a big deal if you have a headspace issue to begin with IMO. That said, neck sizing will always produce better brass life than FL sizing.

FL resized rounds always chamber (provided they are trimmed to the proper length) but spent belted magnums can often become a real pain to remove when using max loads, especially when you are using once or more fired brass. I can guarantee you that if he uses that collet to remove the bulge above the belt, he will have no more problems with max loads. So instead of rolling your eyes why don't you educate yourself before shooting down somebody else’s theory.
I normally shoot belted magnums at maximum loads(real maximum loads for each gun,which aren't always the so called max loads listed in a manual)With some experience a reloader should soon learn the difference between the two.I often fire the same max loads six times or more in each case,and I have never experienced what you describe.However I have seen brand new, never before fired cases stick in the chamber because the load is simply too hot for that particular rifle,regardless of what the manual lists for a max load.As for my reloading education,the forum members that know me,a few of whom have known me for many years from shooting alongside me for those many years,are well aware of what I just might happen to know about reloading and ballistics.
Wade, measuring & trimming cases before reloading is a very good habit to have, & doesn't seem anal at all too me. I made this step part of my case prep years ago.
