Temperature Insensitive Powders and Asthmatic Shooter

I am looking for temperature insensitive powders, and before going to store I would appreciate advice for powder selection. Since my shooting buddy has quite severe asthma, he complained about irritating smell of Unique and 2400 I was using for my 357. Part of the problem could be cast bullets in my loads and in order to help him some of my loads are going to be with jacketed bullets.
He is shooting 9x19 factory loaded ammo only, just to avoid asthma attack and found that some ammo (including several brands from Europe) have much less irritating, choking smell than others. After asking for advice shooters in my area, one of the hints was that double based powders containing nitroglycerin are usually worse than nitrocellulose based only, like SOLO line.  

Here is my wish list:

- Temperature insensitive powders for handgun reloading,   burning rate going from aprox. Winchester W-231 to   AAC-1680/W-680. See    http://www.beartoothbullets.com/rescources/burnrate.htm.   One note: where on the list would be LIL'GUN from Hodgdon?
- Without irritating, choking smell.
- Please, identify which ones are clean burning.

Many thanks on my and his behalf. Onty.

P.S. This post was intended for Handgun Cartridges. Sorry.

Hi, Onty:
  Glad to see another Canuck on the forum <!--emo&--><img src="http://beartoothbullets.com/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''><!--endemo-->. The IMR powders like PB, 7625, 4756 and 4227 are single base and cover the range of burning rates you want, but I don't think they're temperature insensitive. 700-X and 800-X are double based. The VihtaVuori line is single based too, (except the 500 series), but they are temperature sensitive.

  Is the lube on your cast bullets the problem? Some lubes are worse than others. Are you casting your own or buying commercial cast?  I find Lyman Orange Magic lube isn't near as smokey as the blue lube (Thomson Blue Angel?) on some local commercial cast bullets. Orange Magic does have a smell though.  Looks like you could use better range ventilation. Jacketed bullets might be the only answer.

  Lil'Gun is very close to W296/H110 in burning rate, but it's a ball powder, so it will have nitroglycerine.

  Sorry I don't have a perfect answer.

Bye
Jack

Good advice Jack,

I remember reading that LBT's Veral Smith Blue lube was supposed to be easier on the sinuses.

It's also possible the gent is reacting to the priming mixture, which could be quite difficult to rectify.

The cleanest as far as soot, burning powder I've used is the surplus WC820 powder in the magnum cartridges. The ball powders might be the way to go.

He could also try a surgical mask but that's a drag.

Tough one there.

Regards, Ray

Im with Jack and Ray on this one. and what Ray stated on priming mix may be the key as well when using cast bullets after there ride thru the bore they will leave small dusting particals in the air as well as any unburned powder that could be causing your buddy the problems. You may take a look at hodgdons Extreme line of powders for temperature insensitive propellants?
let us now what you find. Have a nice day. Jim.

I'ts quite possible for the nitroglycerin in double base powders to reek havoc w/ people w/ health problems. My suggestion would be to approach this from the opposite direction and for your buddy to do a web seach on 'colloidal minerals' and pick up some- get rid of the health problem- not the powder.

Hodgdon emailed me that H4227 was temp insensitive, for my 44 mag.
