I just started powder coating last month. Been casting for 30+ years. I am amazed at the results. No more gas checks for me.I stopped gas-checking my cast bullets a few years ago.
Over the last decade, I started powder coating and water quenching ALL of my pills regardless of the caliber. I find zero to no leading as long as I keep the velocities under 2600 fps and use an alloy/mix that has a BHN of 16+. For any velocities greater than that, I use jacketed .
In my experience, powder-coated bullets (that I retrieve from the sand berm) don't show signs of gas-cutting, so I figured there is no benefit (to me) anymore.
I also found no improvements in accuracy or inconsistencies in checked vs. non-checked bullets.
As long as it rings steel at 200, consistently... nothing is needed.
Gas check helps stop leading of your barrel. Rifle bullets should be gas checked because of speed. or you can powder coat then Gas check is not neededNoobie question: What is gas checking and purpose? I’ve reloaded 9mm and 45 ACP. I haven’t done any rifle rounds yet.
