Firstly I would like to introduce myself, I am a New Zealand lad that has been brought up with hunting. My ambition to hunt trophy animals in our home land and leave poorer heads has pushed me towards building a specialised longrange hunting rifle.
I have had built a 6.5x.284 Norma. The action is a Kelby (kodiak), shillen sm barrel (29', 8:1, No5), jewel trigger, and McMillan A-5 stock. The chamber is tight at .290' neck diameter.
I have started loading seating the bullet 2 thou into the lands, using 140grn A-max bullets. The cases are Lapua (neck turned), and CCI magnum primers. Power is H2213sc or you will know it as H4831sc.
My load is accurate at 54grns which I am concerned that is too hot and will burn the barrel too quickly. it shoots 5 shots and the base of the case covers all shots at 100yrds. (11mm)
I started with 50grns and worked up and kept getting verticle spread until I hit 54grns. I have not tested the speed of the bullets yet.
Should I be pushing into the lands further and try dropping the powder?
Any help would be appreciated.
