What do you folks reccomend for ammo to break in a new gun? Got a shiny new Bergara HMR PRO in .308 for Christmas from my wife. Haven't had a new gun for Ionger than I can remember. Have a good process for shooting/cleaning, but ammo choices are too big these days. I used to just shoot what I intended to shoot after break in. But with ammo costs these days, no way. And I am not going to waist my good stash for breaking in. Too early to consider developing loads at this point. Will get around 200-250 rounds through it before getting down to development. What say you folks? What type of break in ammo?
