New to Reloading

[Mac 1]

As the title indicates, I am new to reloading. I have cleaned/polished, deprimed, resized, bell mouthed and reprimed all of my brass. I am now ready to load powder and bullets.So far, I have done everything in the garage with no air condition. Do I need to have any concerns with the temperature/humidity and the powder? I will be using Alliant Powder "Power Pistol", Winchester "231" and Hodgdon "Tite Group". I am loading 9mm using 115 grain Hornady FMJ bullets.

I also used a go-no-gauge on all of the brass after the above operations. I have a few that are tight to very tight in the go-no-go gauge. Is there a safe way to remove live primers from this brass for resizing or should I throw them away?

I also read in a previous thread that sometimes folks have issues of repeatability when using the Hornady electronic scales. I have the Hornady electronic scale. The tightest tolerances from suggested starting grain loads and maximum load grains according to my Lyman's reloading handbook is .5 grains. I'm thinking that if I load at the low end of the weight tolerance even if I am off .1 to .3 grains, I would still be within the suggested and maximum weights by .2 to .3 grains. Does this make sense? Any comments/recommendations would be greatly appreciated.

Hopefully, once I get past 9mm, I will move into 40 and 45 caliber reloading.

Thanks,

Mac

Most powder in temp sensitive, better to have in climate control of somewhat, and not extreme temperature differentials.

Do not try and re-use primers, throw them away. I usually just slowly deprime the brass again very carefully if i should ever have to remove a live primer, but it goes away, not to reuse.

I think you are ok in your powder measure, I use the same measurer.

As far a bulging brass, I use the EGW-U undersized resizer and deprimer from Lee. It undersized the brass a very minimal amount but never had a finished round be too tight in case gauge or my gun barrel. All cycle and have no problem feeding, but be aware to use a brass case lube on all brass, because it make it easier as it is harder to resize the brass with the undersize die due to the tightness, and gets a little tiring if not using something like Hornady One Shot case lube, works great.

Reloading in the garage should be fine. If you can stand the temperature, then so will the powder for that time period. If you are hot/sweating then wait for another day. Bringing cool powder into a hot garage may cause condensation in or on the jug. Humidity isn't your friend. Storage is another matter. You should try to keep primers and powder in a temperature controlled environment. The only issue you may have with an electronic scale is with fluorescent lighting. They didn't always play nice together. That may no longer be a problem with newer models, but I don't use them.
+1 for the EGW full sizing die, especially with used brass out of a glock.
