Isn't there a difference in cold stability/tolerance between single and double based powders?

I load equivelant LP 20g loads with either imr 7625 or Intl Clays. I recall a warning about the v/p loss with 7625 in cold weather.

???

Heavy shot in 1960 ?

There are common english combinations of nouns and adjectives. There are also trademark names. Sometimes it is good to keep them separate. Heavy shot - low velocity loads date back well into 1800s, at least.

You lost me for a minute...you meant heavy "payload" and low-velosity.

I'd opt for light payload and high velosity.
