    Ok loaders, my dies are ordered, I have settled on H1000 to start with and a friend is picking up the powder and large rifle magnum primers.
    I would like to load ammo for target this summer and hunting this fall for elk. My plan is to use the same bullet for both. If I am going to hunt with this rifle I may as well practice with the same load all summer and early fall.
    What are your recommendations on a good accurate hunting bullet for .300 Win Mag that will be effective on a big game animal as elk out to at least 400 yards and maybe 500?
    I have only fired Berger 155s in it thus far and it is dead on at 100. Now it is time for the work to begin. I want to be fully prepared for this expensive Montana elk hunt we are signed up for this October.

    I really like the results I got from the Nosler Partition bullets. I shot that black bear (pictured in my profile) with a 300 mag and a 200 grain Partition bullet. I use 4831 in magnum calibers with good accuracy. Good Luck, Joe

    Actually deth, we (fellow shooters who have M700 5Rs)have been using H 1000 in their .300 mags at the range with different bullets. It is proving to make very accurate loads with consistent velocities.
    I would like to develop my own load in my new M700 5R using hunting bullets such as the Nosler Accubond rather than fmj match bullets. If H1000 does that well in their rifles, there is no reason it shouldn't do the same in mine.
    I already have a good supply of 165 Accubonds and some 155 Hornady Gmax but I may need to go closer to 180 grs for hunting elk this fall.
    The other guys are shooting mostly 150 or 168 gr. match.

    I have good luck with H4350,H4831,Reloader 22,and Reloader 19. I shoot alot of Hornady,Nosler,and Barnes bullets between 165-207grs.
    My most accurate loads have been with H4831,but have been very close with some of the others.

    Thanks, Tx, thats the sort of info I was looking for. I have never loaded for the .300 but will be into it full time soon. I did notice that H1000 is used in all bullet weights in the Hodgdon data and it does not build up as much pressure as does some of the other powders. RL 22 looks like a good one too. I will start off with the 165 grain bullets. I have never hunted elk or mulies but only the whitetails here in Georgia.
    I went ahead and dbought this rifle so that I could get going with it and put in plenty of practice both with load and bullet selection as well as shooting it a couple of times a week. I would like to know it like the back of my hand before we make the trip to Montana in October.
    I have also pretty much decided to shoot it a good bit before I decide on whether or not to install a muzzle brake. I know that I would not use it for hunting with unprotected ears.

    I dont shoot a 300 win mag, but if I did I would be shooting it because I wanted to shoot the larger .308 bullets faster than my 30-06 can shoot them. Id be working with the 190gr bullets or larger. Some of the larger bullets in the boat tail design have excelent balistic coeficients and would do a great job on elk. Im pretty sure H-4831 or the newer H-4831SC, or the IMR 4350 will do the job very well for you. Ive never worked with H1000.

    i just went thru a long process of powders with the 300 win mag trying to find a good one for me, i realy like the H-1000 and the 4831 sc they work realy well with sierra bullets in both 165 and 180 gr game kings for me anyways, also tried r-25 , r-22 with good results but better results with the hodgen, but i am no expert only been reloading mag calibers for 2 years. good luck with the process.

    I prefer the 4831 SC for its metering. It will give consistant pwder charges through the Dillon with out the need to use a "trickler". It is certainly not the only powder available, just the one I use.

    As for bullets, a good boat tail spitzer in the 180 gr range is probably the best overall for the .300. Unless you are a world class shooter or professionally trained sniper, you will probably never "out shoot" a bullet put out by one of the major makers ie Nosler, Hornaday, Sierra etc.

    I have been thinking about this one all day. I think you would be best served by a good 180gr bullet.

    Hornady 180gr Interbond

    Nosler 180gr Partition

    Swift 180gr Scirocco II

    Barns 180gr Tipped TSX BT

    Silvertip 44:
    I agree with cpttango30. All of these bullets will get the job done on elk and should work well with H1000. If you would like to shoot out to 400 or 500 yards, you will likely have to try a variety of bullet/powder combinations to get the level of accuracy you will need. I usually use 200 grain Partitions or Barnes TSX's in my 300 Win Mag. The TSX's have proven especially effective for everything from deer to black bear to big Canadian moose. Excellent powders for these heavy bullets are R22, IMR7828, H4831SC and H1000.

    Thanks guys, I have been testing the 165 Accubond and have a few 180s on hand now.
    The Accubond has proven to be very accurate with H1000 and Win Mag primers, but I don't see it reccomended for elk size animals very much. I loaded several small batches with different primers and found they have a decided effect on accuracy in this rifle as well.
    When I order bullets again I will get some partitions and TSX 180s and begin working with them.

    I'm in the process of setting up my third .300 Win. Mag. It is this Kimber 8400 L.A. Police Tactical Model.

    I haven't decided on the scope yet, but I'm leaning torward the excellent Bushnell 3200 Elite Tactical in 5-15X. I have 4 of these scopes and every one of them has delivered fantastic results. The factory supplied rail is of steel and has a 20 MOA forward cant.

    As far as loads I pretty much have but one in the .300 Win. Mag., and that is the Sierra 190 Gr. Matchking sitting on top of 72.2 grains of IMR 4831 powder. This has been one of the most accurate loads I can find for the .300 Winchester Magnum. It is a beautiful 1,000 yard target round that is capable of shooting beyond. Bill T.

    You certainly do have a really nice rifle. Go burn some powder and let us know how it goes. I am just scratching the surface with the .300 and I like it.

    Here's todays target with 83 gr. H1000, Nos 165 Accubond and Win Mag primers. I let one slip, but rest are fair. Also I need to learn to use the Lead Sled. I discovered that I must pull the rifle back all the way into the rest after each shot. I didn't realize that it was jumping about an inch forward after the shot.
    I loaded some more this afternoon to try tomorrow cause I need to do this test again since I basically just wasted powder, bullets and primers today. It is the same load 10 rounds each using Win Mag and CCI Mag primers. The rifle does not like standard rifle primers of any brand. Tomorrow I will pay attention the the sled after each shot.
    Depending on tomorrows results, if all goes well, I will start shooting from prone at 2-3-400 yards on Wednesdays weather permitting.
    Once I have settled on a 165 load, I will continue on with 180s.
