| Hi. I want to take your suggestion and test the 77 grain tipped round with the 85 grain round. I got into Bruno's site to order some and I saw several companies including Hornady, Barnes, and Berger offering a 90 grain bullet. I've had wonderful results with each so I think I'll send all three of them. |

D. Rustick from Arms Tech said he has developed one. However I don't want to use my carbines to test them. So I'm going to choose an 80 grain bullet to test. |
