That’s an RCBS Rock Chucker press. This is for 223 in a contender pistol which is much smaller than my other custom loads. I’m seating the bullets to complete these rounds. Since it’s a hotter load than the larger Bower rounds I’m not seating the bullets into the rifling “lands” of the barrel. I’m using Stoney Point tools to measure the gun chamber so I can seat the bullets with a tiny bit of jump. A couple thousandths of an inch. The tool clamped onto the dial indicator is measuring from the bullet ogive to the base of the case. The ogive is the exact place on the curve of the bullet that touches the rifling “lands”. The red tool above the dial indicator has a fired case from the gun that was modified so it could be threaded onto it. This goes into the gun chamber with a loose but snug bullet. I can push the bullet back and forth until it just touches the rifling “lands” then lock the measuring tool. At this point I have the exact chamber dimensions to the rifling “lands” for that type of bullet in that gun. This is crazy stuff although it’s part if the process to achieve the best accuracy possible.

On the top is my benchrest 6.5mm SS Bower Encore barrel with a Leupold 36X scope. I modify a 444 marlin case to make this round. 444 Marlin is basically a lengthened 44 Magnum round.  44 cal= .429  and I neck the case down to 6.5mm/.264,, Amazing long distance accuracy at 500 yards plus. The one on the bottom is my benchrest 6mm PPC- Palmisano & Pindel Cartridge. Extreme accuracy out to about 300 yards.
