Watch your comp to make sure you don’t get lead build up. I am like you and recently jumped into open with a similar setup. I used coated bullets for a while, then switched to Everglades 124gr HP Version 2’s. They are awesome, and not much more in price.
My gun is 9mm Major, so your gun may not burn the coated bullets as bad. I am seriously addicted to open now, and it’s been fun learning the gun and making different loads to chase the predictable Red dot movement.
Have fun!
