Re: 7mm Remington w/ 160gr Accubonds
I loaded the 160 grain Accubonds in a 7mm mag for a friend of mine last year for a limited entry elk hunt. I loaded 69 grains of RL22 in a Win case with Fed 215 gm primers. The data was av of 2978, es of 19, and an sd of 8. It shot 1/2" at 100 yards, and a 7 1/2" 5 shot group twice at 1000 yards. He practiced with me several times at long range because he was anticipating a long shot, and he ended up taking a 360" bull at 25 yards! The bullet was a perfect mushroom at 72% weight retention!
One thing I have noticed about that bullet though, it's rated bc of .531 is a little on the optimistic side. Every time I have tested it at 1000 yards with several different guns, it has hit a few mintutes low using the given bc in my programs. I believe it's bc is more like .490 to .5.
I have not used the neck reamer you mention, but I would like to ask why you feel you need one. Is there a problem with your brass? Usually, it is much better to use a neck turner unless you have a special idea in mind that only the reamer will do.
If it's not far, it's boring.
