Outside neck trimming trouble

rudiored

I outside neck trimmed a bunch of brass, and now it won't neck down in the sizer die....the bullets end up loose in the neck......What did I do wrong or is it the sizer ??? I finally necked some down in a 7MM die and then shoved the bullets in them to get them to hold......Don't think that is a real good idea, but it worked.....may just throw them all away and start over.....[xx(]

rudiored, when you decrease the neack diameter by turning them down, you will need to use bushing dies. The bushings can be purchased in decreasing sizes by the .001" so you can still get neck tension on turned necks. You could also turn down the expander ball and see if that does it, but the die neck for a factory chamber may not be tight enough to size the case with no expander ball at all.

How much did you take off the necks?

why chase the game when the bullet can get em from here?....

Why were the brass turned? Most chambers are not tight enough to need the brass to be turned.

As mentioned, you can use a resizing die which uses interchangeable neck bushings to adjust the grip, like Redding or Wilson. Benchrest shooter use these dies, but then they have real tight necks and must turn brass or it will not even chamber.

I have a bench gun which mandates turning necks to a neck thickness of .0115 with the custom bullets I use, resulting in a .001 release clearance. I do not even consider turning necks on my factory guns as they do not need it nor is it of any real benefit in such relatively loose chambers.

rudiored Concentricity to me is everything. Bullet to brass to chamber.
For a factory gun With dedicated brass to that gun, all you need to do on the necks is just kiss the high spots after fire forming to your chamber.

In other words, you are taking out the little Micro bubbles on the neck no more than that. So if the neck is not 100% turned. thats ok.

Thanks,,I was just reading where neck turning was supposed to help improve accuracy a little. I probably turned them down too much as I went down to brass all the way around. I think I will throw all the brass away and start over.
