The gloves I use for shooting ( cold, wet, or even when its really hot ) is Foot Joy Rain Grip winter golf gloves, they sell them in pairs, they're black synthetic material - so they keep you warm even when wet / or absorb some of the sweat on really hot days ( like over 100 degrees / where touching a hot barrel in a tournament isn't fun )..
They give me a good positive grip on the gun as well...
I've tried Bob Allen, other leather, etc - and I keep coming back to the rain grip Foot Joy gloves .... 2 pair lasts me a full year easy.
Glad to hear your wife is in it too / I'm a reloader as well - for 12, 20, 28ga and .410 ( and I use the MEC hydraulics, 9000 HN loaders ) - but the Grabber or the 9000 GN are good loaders as well - if you don't have room for the hydraulics.
Have fun ...
