I have a Ruger m77 in 300 winn mag, been shooting Hornady American whitetail in 180gr which worked great for my Bull moose this Oct and a mule deer but both shots where with in 100 yards. Its white tail season here in Sask and wanna get out to 3-400 yards opdwith the gun but the balistics chart states a 20” drop at 300 with a 200 yard 0 which is huge to me. Im new to the win mag as it was my late fathers gun, so is there a better round to shoot for more flatter trajectory? Or am i just gonna have to get used to a huge hold over for long range shots?
 
Seems excessive, mine only drops maybe 7 inches at 300 with a 200 zero. You should shoot it and determine the drop instead of goung by the box.
 
What charts are you using? Even a moderate 300 WM load will drop 6" or so with a 200 yard zero so something is amiss. I strongly suggest you shoot the gun to find out what it will do at the distance you wish to shoot rather than a calculated chart that is only approximate at longer ranges. Congratulations on your moose and mule deer.
 
The 300 Win Mag is a awesome round. It is capable to take elk size game out to 1000-1200 yds. First thing I would recommend is getting a APP such as SHOOTER. In long range shooting you will not be holding over but dialing your elevation and wind drift. Throw out your thoughts on a flat shooting super fast rifle. Yes speed helps, but a super accurate, consistent low ES load is more important than speed.My 300 Win Mag is zeroed at 100 yds and only drops 9.8 inches at 300 yds. 3-400 yds is really not what most consider long range. But would be a good place to start practicing. If you want to get serious start to reload. I recommend the 215 Berger with H1000. Start them 30 thou off and they should shoot good. Here is ballistics on my gun at 1000 yds.
DROP:-248 inches or 23.7 MOA
90 degree wind@ 10 mph: 57.2" or 5.5 MOA
Impact velocity 1717 fps
Energy (ft-lbs): 1407.3
TOF: 1.326 seconds
Elevation where shooting is 1500 ft. Temp of 32F with 60% humidity. Full custom 300 Win Mag, 215 Berger, Federal GM215M, Nosler brass, H1000. 3000 fps velocity. Some guys may get all excited that the 215 Berger is a target bullet Blah blah blah. They just flat out work on game. My elk at 600 yds I believe the 215 helped me get him. Hit him a touch low.
 
I shoot 130 gr Barnes TTSX. Not beyond 200 yds yet and haven't killed anything with it either, but others have. At an MV of slightly over 3500 fps in my gun, to 400 yds it gives new meaning to "flat shooting". Recoil is noticeably less than with the traditional 180 gr and heavier bullets our grandfathers said were required, and it makes the same 30 Cal hole. Wind drift and declining velocity only becomes an issue at more extended ranges.

OP asked about long range. For me Barnes doesn't get any consideration for long range. Heavy for caliber bullets always win. The new Hornady 225 ELD-M may be worth checking out as well. Have not heard how they perform on game though. OR the 212 ELD-X, 230 Berger etc. But as I said earlier you'll be hard pressed to find a combo that out performs the 300 Win mag and 215 Berger.
 
First off; you're reding the chart wrong. The 20" of drop is at 400 yards, not 300. No problem, mistakes happen.

Next off, let's see what we can do with what you already have. Screw the 200 yard zero. Sight in 3 inches high at 100, you'll be 3 high at 200, dead on at 270 and maybe 4-5 inches low at 325. 400 will take about 14 and a hold on top of a deer's back. Or, if
youre like me you'll probably switch over to the post of a Duplex reticle at that point. Dang, things aren't looking so bad.


The simplest, easiest to remember, most dumbed down system that works is the rule of three.

Take any big game cartridge that is reasonably close to 3000 fps, sight in 3" at 100 yards and hold dead on til 300 or so. Easy peasy, and JOCs your uncle.

What's your barrel length and how many grains of H1000? 3000 fps with a 215 berger is up there for a 300 wm. I'm playing with the same combo in my mil spec remington.

For the OP, zero at 200 then set out targets every 100 out to 500 and shoot away. Figure out your drops in your rifle. If you're sticking with factory loaded rounds there may be some better options out there.
 
Ok thanks for the input guys, i dont have a range thats more then 200yards so i gotta find a pit and setup for more distance thats a given. As Dogleg said i’ll just set for 3” high at 100 for now and that should give me the ballpark i need. Currently just running a Simmons 3x9x40 Deerfield scope so no turrents or bdc reticle but from looking at Strelok pro app i have the bottom post of my dulpexreticle puts me dead on at 350 if my zero is 100 which isnt too bad if i keep that in mind. This is a hunting rifle not a target gun so taking a kill shot past 400 is a bit unethical for me anyways.


Just changed my zero to 270 yards in my app and that gives me a 7” drop at 350 and 14” at 400 which is close to the start of the bottom post on my duplex reticle.
 
Ruby76. Gun is built on a Borden action with a 26” Brux. I stopped at 79 gr of H1000. Please don’t try to duplicate this load! Gun is chambered with a custom reamer with extra freebore. My friend built one using this reamer and is also at 3000 fps. Guys over on LRH forum get 3050 fps with 28” barrels so my velocity checks out. Drops have been confirmed out to 910 yds. Far as my property allows me to shoot. This gun is such a pleasure to shoot and is extremely accurate. Finish weight of 10 lb 2 oz. 215 bergers are hammers. Sorry if this is highjacking this thread.

3" high at 100 and at 200?
 
I hate coming to these threads as I always leave feeling very inadequate lol
I need a dictionary for half the terms everyone uses but I still bookmark them with the hopes that they will make sense with enough homework.

I had the gunsmith send my scope off to Leupold, so I can simply turn the dial to the desired meters which is nice but also takes a lot of thinking out of it. A two-edged blade for certain.
I took my bison at 400 yards with a single "Remington Premier A-Frame .300 Win. Mag. 200 Grain Swift A-Frame" but it didn't hit a bone and went straight through the heart. Not bragging, complete luck as I was aiming for and hoping for the boiler room.

thanks for the Rule of 3!
 
My figures agree with Dogleg's quite closely.
If I drive the 180 Accubond from one of my 308 Norma Magnums at 3100 [+-25 fps or so],
In actual shooting at measured distances, I end up with figures like this:
100 - +3"
200 - +3.6"
300 - +1.0"
400 - -10"
500 - -24.5"
600 - -45"
It is pretty easy to see that out to about 345, it is a dead on hold for elevation.
The 300 Win Mag will exhibit similar figures if loaded similarly.
Problem with factory ammo....it tends to be loaded a bit "soft", so MV is lower.
I chronographed one lot of 300 Win Mag Hornady Custom 180 grain offerings.
It averaged 2845 fps for 5 shots.....this is a decent 30-06 load, not a 300 Win Mag.
This simply means that you need to shoot your ammo choice at the various distances
to see what it is actually doing for drop. I still recommend the +3" @ 100 setting unless
you are using a scope with ranging capabilities. Eagleye.

Still seem strange to me that its the same at 2 and at 3. Gonna try it out when my x reload order comes in.

100 and 200, not 200 and 300. The max ordinate is between the two ranges. With a real load it would be higher at 200 if that's what you are wondering.

I'm sort of wondering if I'm supposed to clearing up
MPBR sighting, or explaining that the Hornady load is so wimpy. :)
