My rifle is a remington 700 sendero in 300 win mag. The bullets im most interested in experimenting with would be the Nosler green tip, Nosler accubonds, and the Nosler Partition. For the Partions I would like to stay with the 150 gr cause they seem to bleed off energy real fast past 300 yards. I like the idea of ballistic tips cause I feel like they shoot flatter, and group more consistantly. I understand the concern for ballistic tip bullets because they expand so fast. I am currently loading 165 gr green tips with 70gr of IMR 4831, and 150 gr partition with 72gr IMR4831.
