been using the Nosler 80's at that distance with good results..Has anyone compared these bullets ? Particularly at 300 yds
Same here. I found the 80 SMK made a good direct substitute. I did significant testing from the bench at 100 yards. Then several 20 shot matches at 600 yards. The 75 A MAX may have slightly better wind drift.I doubt there's a lot of difference - it's down to what your rifle likes. Mine still prefers the Hornady A-Max 75g
Looks like I'm in for a lot of testing at distance.
I think the key difference is in the better BC with the Berger.The great thing about the Sierra 80 SMK was how easy it is to get it to fly well. Seating depth could be at the lands or jumped a bunch. Didn't seem to really matter all that much. Same thing with powder charge. In our service rifles the norm has been to determine your short line load then seat the 80 SMK over that charge for 600. I couldn't see any difference on target with the Bergers. Of course my rifles, my game & me jerking to go button. YMMV......
