Depends if you supply the materials you would like to use! I worked a load up for a guys 300 wm that he swore wouldn’t shoot. Using my materials and bedding his action we swapped for a Cerakote job that he’s doing. I provided him documented targets with loads. He was happy with 1/2” groups at 100 yards, he can only get 4” groups out of it but I know it’s not the gun or loads. I think most guys would load develop just for the raw materials replaced or maybe horse trade labor or something. Most reloaders do it for the joy and satisfaction, like other shooters I conquer a cartridge rifle combo then I’m bored and thinking up a new cartridge to play with.If you could pay someone to develop a load for your rifle, What would you be willing to pay?
