I feel really good about having 54 grains extra weight and a lot better BC. BTW I was shooting 69 gr SMK over 25.3 grs varget and BR4's, LC brass , Off top of my head I think BC is @.300 or little higher at 2740 fps. I cant wait to get the grendel going and try it out!
RS:
How about using a .223 bullet more intended for distances past 300? A 77 grain Match King ought to do the trick. There was only one reason why we shot a 69 Sierra at anything past 300. At the time, the only match grade bullet made for the .223 was a 69 grain Match King. It is precisely why the AR-15 / M-16 was not competitive against an M-14 about twenty five years ago. When the longer and heavier match grade bullets for the 5.56 hit the scene -- along with 7 turn twist barrels to shoot them -- the M-14 disappeared in High Power.
Bottom line... No one shoots the 69 Match King past 200 (300 maximum) anymore because the 77 grain match bullets are so much better.
