I got a question for you guys that reload the 300 RUM. I just picked up a Rem 700 long range, so I figured that I would try and work up a load for it. My results were quite poor and I am wondering what your thoughts maybe. -The rifle was brand new. I shot 10 rounds through the barrel before I started. I don't know if that is part of my problem. Is the barrel too new and has not settled down yet, and therefor driving accuracy issues? There were 3 shots at each charge weight: I started here: New Nosler Brass, Retumbo, Hornady EDL-X in 178gr. The grouping was poor at best. The only semi reasonable one was the 94gr load. I cleaned the barrel with Hoppess #9, patch cleaned, and then fired 5 rounds before moving on. The next load was: New Nosler Brass, Retumbo, Nosler Accubond LR 190gr. The Accubonds were better than the Hornady. It looks like 91.5gr is ok. I have not had a load development set where they have had such poor groups in general. I am wondering where I should take this. Different charges, different bullets? I have 8lb of Retumbo so I would like to stay with that if reasonable. Thank you for your input.
