New to reloading, questions on load for .45ACP

[Spawn-Inc]

Resize meaning put throught the resizing and decapping die? What is this Chamfer and Deburr? Is that like the tool I use to deburr resized rifle cases? Should I use that for .45 ACP? I've loaded the same cases more than a dozen times over, and never did those stages of reloading... hopefully I'm not going to explode on my 50th.

^^^ I think by chamfer he means expand the neck to accept the projectile, not too sure about the deburr

i'm thinking he does mean to actually chamfer and deburr, but i personally see no reason to do that, and at the rate i reload, i don't have the time.

Your experience is unique, most of the reloading world, uses .452" sized bullets, which require (for us) a slightly greater degree of belling than usual. If what you are doing works for you, that is fantastic, but it's certainly unorthodox, and just plain not going to work for the majority. All that happens for me and most people using lead bullets, when we forget to bell the mouths, is a wasted bullet, that has been shaved by the case mouth, and or crushed by the press. Again, I'm not saying your methods don't work for you, just that they are unlikely to work for others.

I am also using .452" lead bullets.

To be specific I'm using Hornady 45 CAL .452" 200GR SWC.

If you think about it for a minute you will realize that we are using 2 different methods to attain the same goal.

We're both trying to stuff a .452" lead bullet into a .450" diameter hole.

Using your method you are stretching the case mouth enough to create a funnel.
You are then crimping it back straight.
Either way you're ending up with a cartridge who's external dimension is less than .474" which is the SAMMI chamber diameter specification for .45 ACP.

Using my method instead of stretching the case to create the funnel I'm chamfering the case to create a natural funnel within the case walls.
If the case walls are .010" each I'm creating a funnel that is .020". This is probably greater than the amount that you're expanding your casemouth.

On initial case prep it takes a couple of extra seconds to prepare each case.
When I'm shooting lead I keep the cases separate from from the rest which minimizes the chamfering required on subsequent reloads.

Try it for yourself and you'll see that it works well.
You may even see an increase in accuracy.

oooooooo ^^^ that is interesting

interesting indeed, i would think it may even last a bit longer due to not being stretched and compressed so much, or rather as much.

when i get some more bullets to reload i will for sure try this, guess i also need said tool as well.

The RCBS and Hornady chamfer and deburring tools are nearly identical.
The Lee tool isn't as good but only costs a couple of bucks.
