Re: 230 Bergers and 300 RUM
At 1500yds, the 215 has less elevation by about 1.25moa, and the same drift as the 230 Hybrid (.743 BC version). Out to 1k, it still carries the same 1moa advantage in elevation with roughly the same drift. The 230 OTM has a .711bc, so it would have even more of a difference than the .743bc 230 Hybrid comparison.
The only ones that I have tested are the 215 Hybrid (.696 BC) and the 230 Hybrid (.743 BC). I have not shot any of the 230 Tacticals, so I cannot reference those. Both have been shot out to 1500yds and the 215 does definitely use less elevation and the same drift. I couldn't get the 230's up over 3050 in a 28" barrel without hitting pressure. The 215's were not an issue at all to get up in the 3175 range in the same 28" barrel. Both are great bullets for the RUM, but I think the 215 is a little better balance. It hits almost as hard, but has less elevation with the same windage.
