Mine currently has a 8.5-25 Leupold 1” tube with turrets. I shot 70BT’s that were still loaded from a p dog shoot I was just back from. All were small southern white tails and ranges were all 371-491. All lasered. Except one that was so close I just shot her...best guess 225 or so. It killed like lightning. I think my initial question was perhaps misunderstood. I found it perplexing that my 6 Ackley was shooting essentially the same velocity as a std 6 mm rem using std 6 mm data. What I mean is a 300 mag can be shot at 3006 velocities but it is still going to require more powder to do it

For instance, using Nosler data, both rifles 24” barrels:
3006 165 gr bullet W760 56.0=2882fps
300 win mag 165 W760 63.0=2866

Essentially the same velocity but the larger case requires more powder to get there.

I’ve tried 85 partitions but they shot poorly. I’ve shot 85 bthp sierras and they were very accurate. I’ve also shot 87 VMax and it also shot very well. .3 moa out to 300 yards. The farthest I shot it. It would not shoot 100 Sierra flat base. If it shoots the 90 BT’s I will probably put a 4.5-14 Leupold w/turrets on it and just let her ride it out easy shooting deer and coyotes. When it gets a new barrel probably go 9/10” twist and just keep using it in the same roll. But probably thread it and put a suppressor on it.
