Newbie Reloading Question

[kuma32shaq]

So I have my Dillon 550B setup and ready to go for .40 S&W. Dies are somewhat set. The question I have is which information do I use? I have Nosler 180 gr. JHP and also Hornady XTP 180 gr JHP bullets. The powder I have is Accurate No.5 and IMR Hi-Skor 800X.

Do I go with the powders manufacturer information or the bullets manufacturer information?

I have the Lyman 49th manual, but it only shows info for general 180 gr JHP

Any information on what is best would be appreciated or if anyone is willing to share their receipe for any of these combinations.

Thanks

Sean

stick to your reloading manuals


i'm betting in about 2 weeks you are going to ask why some are not fitting your chamber

research the "glock bulge"

Start at minimum & work up. Make sure to keep notes on charge weights & OAL. Weigh carefully. Watch for pressure signs.

I like to find different sources for data & compare.

Good luck.

unsuported chamber used in glocks. the brass bulges a bit at the base.

Some of the older glocks have very loose chambers. It's what makes them so reliable. The looser the chamber and the higher the pressure can equate to brass that "bulges" to the fit of the large chamber. Hence, in older glocks, especially 40 caliber, at some high pressures the brass would bulge causing it to not reload properly without a "bulge buster" or very well set die (not a Dillon die, BTW).

In realty, his phenomenon only happened in very early model glocks, and isn't really anything to worry about with any modern pistols. I have never come across the problem and if I loaded 40 (which I don't) I wouldn't worry about it at all.

The Glock bulge is more of an Internet urban legend than anything else.

Yeah I would be shooting from a Springfield XDm 40 so no Glock here . The problem would be mainly if you were to pickup range brass right? You wouldn't know if that was shot from an older Glock.

Getting back to the main question. Does this look somewhat right?

its best to get the data from a few sources and start at the average. If you want to be even more safe you could take off 5% from the average and work up from there.

Right out of the Lee book.
