How far with 180 grains and a 300 rum?

I have been trying to get my 300 rum to shoot 200 ab and 210 bergers. But its not going to happen, It loves 180 ab. So my question is how far can you shoot an elk with 180 ab. What is the longest shot you would take?

It depends on an awful lot of things including the shooters ability, optics, knowing the exact range, weather conditions and a host of other things. Having said that, the round and bullet combination is capable of killing an elk at 1000 yds. I would caution that the accubond will not expand reliably at velocities under 2000 ft/sec ,however!....Rich

If I’m not mistaken Nolser has posted on their web site the minimum velocity for the Accubond to expand properly is 1800 fps. Using the info on Noslers website an 180gr Accubond with a BC of 507 and a muzzle velocity of 3225 slows to that at about 825 yards. If you consider the established ft-lb of energy it takes to sub do an animal the size of an elk (1500 ft-lbs) then with the 180gr you would max out at about 725 yards. The numbers above are at sea level. So with altitude it gets better.

I have seen elk taken with a lot less than the 1500 ft-lbs rule but would take Noslers advice on how their bullets perform and their limits. As elkaholic says there are a lot of variables and everyone needs to work their way up and find their own limits.

I would keep foolin around with the 200gr as it will perform better. Good luck.

What twist is your BBL ? If you have not tried 190 bergers and retumbo do try. What disatance did you try to group the 210's ? Some guys have noticed the beregers dont go to sleep till 250-300 yards. Mess with seating. I found a good node in my rifle at 3.70 " 100 yard groups are 1" .. same at 300 yd. Dont forget the 185 bergers too.

Conservatively, at elk altitude the 180 AB starting at 3200 FPS still has over 1800 FPS and over 1300 pounds at 1K. This is at a reduced BC and the lower elevation limit for elk of 6000'. Some elk will be found lower but not many. This is of course with the western states in mind. Elk are tough but with a high shoulder shot theyre not going anywhere. IMHO, the 200 AB is only marginally better. I had the same issue with both of my 300 RUM's. They loved the 180 AB's and only tollerated the 200 AB's. One with a 12x barrel and one with a 11.25x barrel. Both would shoot the 200 AB's at .5 MOA where both shot the 180's at .25 MOA.

Re: How far with 180 grains and a 300 rum?

You might want to consider the 168 grain Etip over the 180 accubond. The BC on the bullets are almost identical but the 168 should be able to be lauched around 100 fps faster which means flatter trajectories and less wind drift.

The higher velocities downrange of the Etip and near 100% weight retention should mean good terminal performance also. At 900 yards the 168 etip is still travelling at over 2,000 fps at 5,000 ft elevation

If you have a minimum of 1-10 twist you can run the GS Custom HV hunting bullet at apx 3500fps and carry down range farther than anything else in a hunting bullet. Well past 1000 yrds.
