I use it for 223 and 300 aac and it works well for both of those. Thinking it might be a little slow for 5.7?

Be VERY CAREFUL!!!!! Burn rates are calculated in a very specific way.

When you start loading even very slow powders in 5.7 once you go above 40k psi how the powder behaves changes DRASTICALLY.

Powders are designed to operate in a give pressure range. The increase in burn rate is NOT linear.

Tread lightly.
