41gr
2980 was old velocity data. Barrel apparently sped up because last time out the 95gr classic hunter chrono'd at 3050 @ 41gr h4350. Obviously some room to run powder charge wise but it shoots well so I haven't messed with it.
I wouldn't start at 43. Berger data shows a range of 38 to 42...
Me too but most of my hunting is out of state nowadays, so I haven't dabbled much with copper. My 3-4 attempts with copper bullets over the last 15 years has been frustrating.
108 eldm, h1000 or h4350, new lapua/starline/Peterson brass would be my starting point.
41.3 h4350 with the 108 in starline brass is a tack driver in my 1/8" twist tikka.
