What you are referring to is chamber forming the brass. When you shoot a round in a bolt action rifle, the brass custom forms to that chamber. Now when you reload, you neck size only. And you can taper crimp the bullet. You still need to check the length of the brass and see if it needs trimming before loading.

On semi-auto rifles it's still wise to full length size the brass and roll crimp the bullets.

thanks for the clearification................

My .40 Lee dies didn't remove the Glock bulge so I tried the EGW undersize die that does work but it is also stretching the cases about .004 inch causing it to not go into my gauge. Gauge seems to be a little under the .850 max. Pretty new to .40 reloading, has anybody had this problem?

Thanks in advance

If I'm not mistaken. That's why they sell a thing called a "case trimmer".
Sorry, I just felt being sarcastic today!

The brass was advertised as once fired. Haven't seen anything that made me suspect otherwise. I sized about 1000 of them (wore my son out) with the standard Lee dies, about 1/3 of them would not fit into the gauge due to the Glock bulge. Bought the EGW undersize die and yes it does a great job removing the bulge but was just surprised the cases were stretched so much after they were already sized.
Again kind of new as this pistol stuff, trimming rifle I am use to but was under the impression that pistol ammo you didn't have to trim as much.

How many of you trim your pistol brass?

I had hoped to just use the EGW die in place of the standard Lee resizer but don't think I will now.

Was just wondering what other EGW undersize die users had run into.

Thanks

i was under the impression that pistol brass never stretched...... then again i have had brass that was really tight in the case gauge but chambered perfectly... so honestly i quit case gauging and just chamber check....

never trimmed any pistol brass either....
