I am working up an accuracy load for the 223 cartridge for the Ruger American Ranch rifle with the 16-1/8” barrel. H335 isn’t working out too well and as I understand can be temperature sensitive. I use the rifle in Montana where we have significant temperature extremes. I want to use a a ball or fine powder so I can use the powder measure and not have to trickle every charge. What loads have others used with success in this firearm.
