7mm Remington w/ 160gr Accubonds

[7ultra]

Hey guys, just bought some more reloading components. Anyone have any pet loads that shoot well for the 7 Remi and 160gr accubonds. This past fall I used Re 19(62gr?), and while the results put down a deer alright, I want a little tighter shooting load. Any Input is appreciated.
PS. I also picked up an inside neck reamer for my Forester trimmer in 7mm. Has anyone used this, and how does well does it work?

Loaded for my dad's 7 mag last fall for our elk trip used 65 grs. of H-4831sc with Win brass, 215m primer and 160 Nosler AB. Load averaged 3/4 moa. Didn't get a chance to chrono-my pact was getting repaired.

BTW-this bullet was also used by 2 other hunters with great success on deer and elk.

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.

Thanks for the load advice guys. I bought the inside neck reamer with the designed intent to smoothout/make the inside of the neck more consistent. I think this would improve the contact between the bullet and the neck, and reduce irregular friction(from case to case). Its a thought, I don't actually know if its going to work.

one thing Goodgrouper failed to mention is that his father borrowed my 7mmRem Mag loaded with 68gr imr7828 with 160gr Accubond's at 3000fps to harvest a record (for the unit) Desert bighorn Sheep.
If you are planing on inside neck reaming your brass with a standard reamer you are wasting your time

I ran a ladder test on my 7 mag and settled on 66.3gr of 7828 with the 160 Accubond. MV is 2975 fps and it shoots .5-.6". Best load I have found for my 700 classic so far.
