70gr rdf has a BC of .410 and from what I read people are pretty happy with is and getting over 2800.. This Friday I'm going to the range to chrono my leverevolution load with 75gr Hornady and 77gr Sierras. Will let you all know what I get. I been tempted to buy some of those 77gr RDF bullets.
If you've got a good load for the 70 RDF in an AR, please share. I hear these rumors repeated of people being "pretty happy with it", but everyone I've talked to who actually uses it (myself included) had trouble getting it to shoot well in an AR. I really wanted to like that bullet, but didn't find a solid repeatable load for it; none of the good results were repeatable over multiple range trips. That seems to be the general consensus of it on the snipershide forum as well.
