Alt Powder for 700x

Anyone here reload with Perfect Pattern or High Gun?

I’m about to run out of 700x and it’s very difficult to find. Been reloading with it for about 8 years and I’m used to it, but it’s rare as hens teeth, and when available on the secondary market, way over priced.

Two powders seem to be available most of the time, Hodgdon Perfect Pattern and Hodgdon High Gun. These seem to be more reasonably priced and has better availability.

I’m looking for opinions on those two powders and open to other suggestions for a 700x replacement.

What are the burn rates ?

Perfect pattern is a bit faster than 700x and Hi Gun is a smidge slower.

Also considering Alliant Promo and Clay Dot, as they are very close in burn rate.
