good idea,,That base plate is the key to the project.What or where did you find or use for the base plate? My set-up is not that portable and I'm just a backyard plinker but I have a roomy backyard. I use a large block of wood with an arch cut into it that I lay a couple of lead shot bags filled with sand-box sand and a caldwell rear bag.My shooting bench is a stainless steel chefs kitchen table I got from cosco's,it's light and easy to pick up and a short wooden stool from wal-mart. Storage is very near by,takes about a minute to set-up. I used my carjack as a press. Made a frame out of 2x4s and 4x4s. Inverted the jack.Was making paper bricks 2 burn in a wood-burning stove. Worked very well.
