So first please bear with me, I have seen dozens of "270 for elk threads", but none about the new .277" Accubond LR 150gr.. I know the bullet was just released but what are your thoughts on it. I am using IMR 7828 with the accubond lr 150gr and get aroud 2800fps. I have used the accubond before in 140 and its great but I want to use the 150 for my cow elk hunt this year. What should I limit my range to and do you think It would penetrate the shoulder at say 400yds? Or should I try a different bullet oe try to get 2900 fps? Should I limit the shots to less than 400yds? Btw the Accubond 150 gr LR has a BC of .625. Thanks for your thoughts and advice.
