I am still working up everyday loads for the 5.7 X 28 for my PS90 and wife's pistol.

Currently shooting 6.0 grains of HS-6.
But all 5.7 nuts like True Blue.

But I cannot find it anywhere in central Ohio.

What would use to replace it?

Checking a couple burn rate charts Accurate Arms #5 and your HS-6 are right next to it. If you have a nice load for your pistol using HS-6 I sure wouldn't worry too much what the other "nuts" are using.

Winchester 540 is another powder that would be very similar.

Thanks, All
I agree with you Paul.
Thanks for the burn rate chart.
It is more complete than mine.

I DO enjoy shootin the wee rifle case round!
