Temp insensitive powders and barrel heat

[Lefty Trigger]

Might be wise to get a temperature strip for the side of the barrel.

I actually bought a 10 pack of those and as soon as I remember where I put them I'll get one installed. If I remember right the max temp not to exceed was 140 degrees and I think the temp strips were 85 to 140 range,... now if I could just find them...

Either speed up or slow down your shooting process. Both require the shot tobe taken with the shortest amount of loaded chamber time.

I live in the desert and 100 degrees by 10am. How about a cartridge straight from the cooler. Hot barrel and cool round. Silly?

Ive also been playing with that here in the Desert, with rounds out of my cooler into a Hot barrel during a Match.
I dont think it hurts anything, and may help some...its been too windy here to tell for sure but ill keep
messing with the cold ammo to see if there's any benefit.

I think that if you developed your load with chilled rounds and shot in hot temps with a hot barrel, you are doing everything you can to maintain control over powder temps and burn characteristics.

I've got a battery operated air pump that does a great job of cooling the barrel down to ambient in the hot Texas summers. I may have to add a cooler to my already too heavy range box....LOL

I was doing that years ago in competitions with ice packs. Wrap soft ice packs around my ammo boxes during the shoot. Kept all the ammo at a cooler temperature without overheating. Not sure what people do today. Maybe put the boxes in coolers.

Now if I could just get a little help with the wind out here in Arizona, I might do a little better than a 579...ughh
Oh well some days are better than others, and some downright depressing. lol

Look at powders SDS or MSDS to see it it contains one or more of the above additives?? I have not checked.
