to keep the temperature even through out the shoot, I have done it when shooting F class on a hot day don't know if it helped but it didn't hurt

Thanks for mentioning that mate.

They were the next things I was going to explore. Powder and powder types.

And secondly if there was anything you could do too lessen the effect, by way of ammo storage on your person or in a piece of equipment like a cooler etc.

I have held a number of rounds in my pocket during the winter for a test.
Tried with both .223 and .260

Fired them over a v3 and the ES was all over the place compared to the same loaded batch of ammo I had on the bench.
Was an eye opener and sort of what led me down this path of thinking and testing.
