.300 wsm shooters

[Huntbear]

the 180's have aprox 200 more ft lbs of KE at 500 yards . the 165's 1.3 at 100 and -17 at 400 . the 180's 1.5 at 100 and -19 at 400 at 500 yards the 165's drop 39 and the 180's drop 38 . so past 500 i'd go with the 180's better bc and energy.

This is very accurate.  My brother and nephew both shoot the 300 WSM.   I have loads worked up for 180 gr. accubonds.  If you look at the BC for that bullet, when it comes to long range (anything past 500 yds.) it beats the 165 gr. hands down.  I am not where I can get my hands on the reloading data right now, but I believe the 180s are coming out of a 22 in. pipe at almost 2900 fps.  Use nothing but Magpro powder.  CCI magnum primers.

You all are confirming my thoughts of getting 180 accubonds, but i do like the 168 berger ballistics

how much energy do you need? I'm sure this 6.5 creed has less energy than the 168 when it kills this elk at 600 yards.

feature=player_embedded

ofcourse i take energy over speed if i have to choose, but neither of them have clue compaired to putting the bullet in the right spot.

For the purpose of a scope turret you really need to shoot them in your own gun out to your range you want to shoot (you said 700) and count your clicks and also shoot over a chrony. Make sure the turret actually matches what is happening.
Oh and I would go with 180 accubonds over the 165 accubond.

Since you are dialing the scope trajectory doesn't matter how flat it.shoots. you dial in anyways to what your rangefinder says. Higher BC and heavier bullet will be les affected by wind.

now this makes sense.

I just reread this, and realized you are talking about using a CDS scope.

They will want your data on the following....

Bullet size
Velocity
elevation you plan on hunting
temperature you plan on hunting in.
atmospheric pressures if available.

This has to be real world data to your gun, and your situation.

I shoot 180 gr. Accubonds. I have similar calibers that I shoot lighter weight bullets out of.

  from Ammo and Ballistics fourth edition. 300 WSM.
It does not show accubonds in 165 grain,so I compare Barnes triple shocks in 165 and 180. I will show 200 yard zero, 400, 600, 800, 1000 yards. This is a Federal Premium loading.

165, 3210 fps muzzle:  0/ 2630         -18.8/2190       -67.1/1788      -159.6/ 1446        -319.5/ 1185


180,2980 fps muzzle:   0/2570           -19.7/2200       -68.2/1865       -157.2/1564        -303.7/1312


accubond, 180, Federal premium load

180, 2960 fps muzzle;  0/2600           -19.2/2260       -66/1948           -149.8/1666        -284/1420

thems the facts Maam!

Out to 500 yards or so, bullet weight and corresponding BC are not really a major factor to consider.  Pick the bullet that your guns likes best.  When you start getting out to 600 and beyond, then ballistic performance becomes more and more important.  Recognize that with modern technology (i.e. laser rangefinder and turret scopes), drop is not as much of an issue as it used to be.  Whether a bullet drops 80 inches or 100 inches, the turret is adjusted accordingly so the bullet goes where you aim.

Accuracy is king when you're shooting at very long distances.

In an ideal world, you will shoot a bullet with a BC of 1.0 that groups 1/8 MOA, with no recoil and perfect terminal performance at every velocity, every time.  Dream on.

I have also found that I like a turret marked in moa instead of calibrated to round specific. This allows me to alter for weather and atmospheric conditions as well as tinker with load. There are plenty of online ballistic calculators to use for.making a drop chart for a specific hunt or shooting condition. If you have a smartphone go and download strelok it is a free ballistic calculator app. I have tested it out to 850 and is right on. As accurate as inputs of course.

I chose the Winchester Supreme 180 bonded.  3010 fps.

I was thinking 165, but liked the wind bucking ability of the 180 better for long shots

I shoot a Berger 185 using IMR 4350 out of Vanguard Sum MOA with a 24" barrel.... gets me about 2800 FPS on average.

Im a high BC fan.. and this bullet retains more energy from 300 yards traveling at initial velocitys of 2800 FPS than other conventional 180 grain bullets traveling at the 2900+ range.

I have also seen what it does to an Elk first hand at 200+ yards... really nice bang flop.

I don't have a load for smaller game... Just a load for 180 Grain Barnes TSXs.. the Rifle LOVES these bullets too..

Honestly, I dont see myself going with a lighter weight bullet. With a High BC heavy weight bullet you get more energy than the lighter ones and if I am worried about destorying meat on smaller game with it, I will just switch to the other favorite bullet it likes, Barnes.

So my  is with 300 mag calibers.. for an all around bullet for your rifle, I would choose the Berger and Barnes at 180/5 grains and get two CDS dials made. This is exactly what I did on Leupold VXR.
