I've not yet shot my new Sako 75 Stailess 7mm08 and need to break-in barrel. Being I don't have reloading equipment and plan on shooting factory ammo for now...I'm wondering if it matters what type of ammo is used for the break in? Would it be OK to use the cheaper line of Remington,Winchester,etc. in the 140 grain bullets or should I use what I hope to be the ammo that is better for deer hunting like Hornady SST or Remington AccuTip which cost more money. I just don't know how reliable the one shot and clean method during the break-in is for testing ammo for accuracy at the same time. When it comes right down to it I've only broke in one other center fire rifle in my life and that was a Browning Boss Rifle so ammo testing wasn't being done since I had planed on adjusting the Boss to the ammo. Thanks to any input on this subject.
