When taking shots of 500 yards or more the 142 ABLR has been perfect on deer and elk for us. We have had success with several other projectiles but the penitration and wound channels left by the 142 ABLR at longer distances is impressive. I hear some say their rifles won't shoot them accurately and I have also found it may take a little more time to find the right combination but have normally been able to dial them in. Close shots are also effective but damage can be extensive. With shots less than 500 yards any good hunting bullet will be fine but if I plan on reaching out further the ABLR is my go-to. Attached typical wound channel left from 142 ABLR shot taken between 500-600 yards with MV of 3000 fps.
Use 140 grain Accubonds if you can get them. I wish I could have all the money back that I have spent on different bullets for my 260 Rem. and 6.5-284's. For hunting, the 140 Accubond has performed very well and the ballistic (on paper) advantage of high B.C. bullets has proven to be minimal at best. Another benefit is 140 grain ballistic tips shoot to the same point of impact in all of my rifles which saves money for practice.
