Since a 7mm rm is capable of 3350+fps with a 140grn pill in a 26" barrel, and accurately I might add. Why do you run them under 3100? I just saw some of the last data posted up, why waste powder in a 7mag when a 280rem/284win will do that with less powder in a 24" barrel.
Sorry 'bout the thread derail.....
Pretty simple bw83, if you must know....
I simply started my load development there with this particular rifle. After shooting the first few, I simply stopped there, due in part because of time constraints and the approaching deer season. Plus, I primarily hunt with handguns, and this rifle was my backup plan, and was also gonna be used by my wife during rifle season... that help with your question?
Not the vld, but I worked up a load for the 168great classic hunter, with H100 and fed215M. They shot 1/2map and didn't seem to care much about seating depth, as for on game performance, I smacked a muley in the chest at 50yards found a hole going into the off side shoulder but only 1 small piece of the jacket, ripped the bottom off his lungs though
Keep in mind the animals we shoot for food and display are not bullet proof. Contrary to popular belief, they bleed and die just like they did a hundred years ago. Being competent with a given rifle is far more important than impressive ballistics and poor shootability. High velocity misses never put a steak in the freezer.
Winchester, Federal, or Norma brass 168vld .010" off the lands
H4831sc use fed210M primer, start around 63.5grns and work up, pressure likely to be found around 68-68.5grns, if you get an ejector swipe back .5grns, that should put you at 3060fps +- 20fps.
H1000 start at 68grns with fed215Ms and work up, probably top out around 73grns, again when you see the swipe back off .5grns this should give you 3130fps +-20fps.
Retumbo use fed215Ms start at 69grns work up, probably top out around 74.5grns, may be compressed slightly, do the same as the others, if your rifle likes this bullet/powder combo you can safely and accurately run the 168s at almost or slightly over 3200fps, depends a lot on the barrel.
The 7mm rm is a great round, not quite as peppy as the weatherby but, most of the 2.495-2.549 length belted mags run at 64-65k psi, for some reason saami decided the 7mm rm should only be 61k psi which makes it seem like a terd, and with factory ammo it is, but when loaded right it is very respectable.
Hey all thought I'd add my 2 cents worth
I have a tikka t3 7mm mag 24 and 3/8 inch barrell,that's standard.
Bell and Carlson stock
Radial muzzle brake
Leupold vx-3L 6.5-20X56
Anyways back to the point,I run nosler custom brass,cci large mag primers,75.5gn adi 2225 or retubo for you people away from New Zealand or auz,pushing a 162 A-MAX seated at max tikka mag length doing 3075fps.
Works bloody well and no excessive pressure signs.
Groups well,consistent 1/2 MOA,drops sika deer well.
