Dr. Mike or someone else, I would like to have the following ran if you can.

Thank You in advance.

George you’ll be please. I used the bullet on crop damage deer. 5 of 6 didn’t make a step. Entrance wound 243 size, no exit wound. The 6th made a few yards and had an exit wound. All does, all double lung. I used RL26. Chrono’d a little under 3300fps.

I used 4831 for accuracy, but RL26 was right there with it.

mjcmichigan, I have been using the Sierra 85HPBT since 1976 and yes it is a good bullet. This request for a rifle I haven't shot sine Nov. 2005, I have used the bullet in the rifle but never knew where I was with it. I have always used 45.5gr IIMR4831 and the last eight five shot groups I shot with were all well under 1".
