New reloader

I'm reloading 300 win mag, 180 gr Nosler Accubonds, in once fired but old Speer brass, RCBS dies and press. When seating the bullet, I get small bits of copper around the edge of the case mouth. Is this normal? Will it accumulate in the seating die? Do I just swab it out?

Re: New reloader

No not normal. My guess is you need to chamfer the inside of the case mouth just enough to remove the sharp edge especially if just trimmed to length.

Re: New reloader

+1 to what Jim said. Any grooves or digging into your copper are going to affect the bullets flight, especially at longer distances. It can also happen if your necks are way to tight on your brass... But that's very uncommon. If you are chamfering your case mouths and still having issues, get a rotary drill, chuck up a 3/4" socket and fill the socket with 000 or 0000 steel wool. Spin your drill up to high speed and push the mouth of the case into it for about 5 to 10 seconds. Check to see if the mouth is smooth. Seat a bullet and see what results you get.

Welcome to reloading. It can be a joy and a pain, but if you keep at it, it's very satisfying to create rounds that are devastatingly accurate out of your rifle(s). There are a lot of experienced reloaders here that will be happy to help you... But also, don't forget to search for answers because it's likely that someone else has had and asked about the issue you are having.

Good luck!

Re: New reloader

I have the same problem. I am using Lee reloading dies. I removed the expander from my 243 decapper/sizer die and and measured the widest part of the expander. It only measured .234". That means the brass is about .233 inside diameter. That's much too small, isn't it? How big should that expander ball be?

I've noticed the same problem with my 300 WSM loads - they always shave a bit of copper off the bullet. I have Lee and RCBS dies for the 300. I guess I'll measure both of them.

When I reassemble them, is there a trick or something to get the decapper/expander exactly in the middle of the die?

Typically expanders are .001-.003" under the diameter of the bullet. Are you lube-ing the inside dia. of the case mouth when you size because that brass will wear out an expander.

Leave the expander loose. It will float and center itself.

Re: New reloader

Are the bullets flat base bullets or bevel (boat tail) at the bottom? You might have a slightly larger diameter bullet base when compared to the bullet shaft.

Making sure you have a good bevel on the inside of the neck is good advice.

tailbon3 - I lube a case and run it up into the die before I tighten the die in the press and tighten the expander mechanism in the die. I also favor the Lee die rings with the rubber o-ring. They seem to account for slight misalignments in the system.

Re: New reloader - neck size

I will definitely pay more attention to the case neck lube. I used to only use a tiny bit of lube on every other case. I ordered brand new Lee EZ X pander decapper rods for 243 and 308/300wsm. I'm got bad feeling those will be too small also :-/

I use both flat and boat tail bullets. Both seem to have this same problem.

Anyone else have any problem with Lee Expander rods?
