I’m in the process of sighting in my new Howa .308 and have a few questions for you guys. I just finished the barrel break in process that is recommended by Howa and that Randy has posted on YouTube. Now I’m working on sighting it in and finding out what ammo it likes. I’m starting off with Nosler trophy grade partition 165 gr. and Nosler trophy grade accubond 165 gr. As I finished the day I got a 3 shot group with the accubond at 200 yds. just under 2 3/4”. This was my best group and i probably sent 40 rounds through it by the end of the day with the finishing up the break in and sighting in with the new ammo. I’m trying different ammo to see what the gun shoots best. Is a 2 3/4” an acceptable group for this gun or should I be able to get this gun to shoot tighter groups at that distance? I’m not new to shooting but hunting in my home state I’ve always practiced at 50 to 100yds., so 200 and beyond is pretty new to me. I know I have a ways to go. Does a gun shoot more accurately after say it has had 50 or 100 rounds put through it or does it matter? Also what about shooting with a dirty barrel ? Is there a certain number of rounds you want to send through a barrel before you feel it is shooting at its best? Thanks in advance for any help or advice.
