Full length resizing

[MikeBjerum]

I am starting to reload .40 S&W and have been told, advised, warned that I need to full length resize.  I have never done this on other calibers and need advice.

What is a good die to get, do you set up a single stage press and mass resize while inspecting, what do I watch our for ... anything else you can come up with.

In the little research I have been able to find (and it isn't much out there) I am wondering if this is something that would help with my reloads for my .45 acp open.  Any ideas or suggestions?

While I do not reload .40S&W specifically, I do reload the other.  You should always full length re-size for use in autoloaders. Anytime I have not I run into feeding problems.

Any of the die sets you get for pistol calibers should be capable for full length.  I use Dillon, RCBS, and Lee.

All pistol and revolver calibers require full length resizing. Bottleneck rifle rounds like the .223 and .308 can be neck sized only if they are going to be fired in the same weapon. If you are reloading for a semi auto rifle like a AR-15, or a Springfield M-1A you not only should full length resize, but it is wise to do so with a small base resizing die.

A small base resizing die will reduce the size of the fired case to minimum dimensions, and provide reliable chambering regardless of the rifle it will be fired in. I use a small base die in all of my .223 / 5.56 MM reloading because the ammunition I reload will be shot in many different rifles. By using a small base resizer die I know any and all ammunition reloaded in it will chamber regardless of which rifle I fire it in.  Bill T.

What I am getting advised on, and there is a set of dies out there for .40 is a "push through die" that resizes further down the base than the regular resizing dies.  I'm on the road, but this weekend I will grab an issue of Front Sight for the ad on a push through die.

If you purchase a Lee Carbide Factory Crimp Die it has a Carbide sizer ring that the entire loaded cartridge passes into. If it goes through the die, it will chamber in any gun. Their dies are inexpensive and easy to use. I have one in every pistol caliber I reload.  Bill T.

Yes full length resize your 40 and 45 brass. I have seen some 40 S&W brass with a ring just in front of the extractor groove that is apparently caused by a non-fully supported chamber. This is why the push through sizing die. If you have a fully supported chamber (leaves none of the case exposed when in the chamber) you won't have that problem. The 45 ACP doesn't have this problem due to it's lower chamber pressure. DO FULL LENGTH RESIZE IN ANY CASE FOR HANDGUNS! It helps.

Hope this helps you.

just avoid glockerized brass and you will be fine.

On auto pistols, full length resizing is the good deal, I like the Dillon carbide sizers, they give a wasp waisted look when finished, and feed perfectly.Accurate too. Bottle neck cases can be neck size only, if to be shot in the same rifle, with a gain in accuracy, normally.

I believe Reading has a "Push Thru" Die that is supposed to take out the Glock bulge.  It seems to require a single station press to work best.  I would also check into the catch bottle.  I think they call it the G-Rx but I'm not 100% sure.

FWIW

Same here....crimping die on my 4 hole Lee turret press and I have virtually no problems with chambering my reloads.
