My question- what would be the better powder choices for handloads
in a suppressed rifle. Calibers 308 and 223. Bolt action. Cleaner burning powders with minimum muzzle flash?

With silenced loads, low muzzle pressure is indicated; therefore you should use the fastest powder that will work. That should also help with muzzle flash and powder fouling in the suppressor.

Most reloading manuals will have some "reduced" loads with subsonic velocity - IIRC, powders like SR4759 are suitable for this. (I don't have a loading manual with me right now so I'm going by fuzzy memories here, so you'll have to check the manuals yourself.) This type of load should be quietest for a suppressed rifle.

If you're willing to put up with the ballistic "crack" of a supersonic bullet, then whatever powder requires the lightest charge to get up to your desired velocity level would probably be best. Don't go below recommended minimums with standard powders, as reduced loads in bottleneck cases have been known to generate anomalous pressure excursions which can damage both rifle and shooter.

I am not sure what you are trying to achieve.

You want to use the most accurate load that shoots at the velocity you desire using the bullet that best suits your needs.
Just like any other load.
The fact that the rifle is suppressed doesn't change any of that.

I shoot the same loads I have always used with or without the suppressor.
