as far as I know there is no such thing as an accuracy load in any rifle.......there are bullets that traditionally have proven accurate in so many rifles that they become a "go to" bullet for such use......but the term "accuracy load" is a misnomer.

Try Nosler's Ballistic tips of 165-180 grain in that gun.....these are as close as it gets for accuracy.

I have messed around with several 300 Weatherby rifles. In general, they have all shot the best with 180 grain bullets.

One load that has consistantly shot well for me is a Weatherby case, a Fed 215 primer, and 82 grains of H 4831 or RL 22 behind a 180 grain bullet. Some of them prefered the Hornady Spire Point, but mostly the best groups came with the 180 grain Sierra Pro Hunter. I am lucky, my own 300 Wby Mag shoots the 180 Sierra or 180 Nosler Partition to the same point of aim.

For some unknown reason, the worst hunting bullet I have tried in the 300 Wby Mag is the 165 Nosler Partition. Maybe it was just the batch I had, but they were pretty sorry. A couple of rifles that would shoot under an inch with 180 Partitions would go 3 to 4 inches with that box of 165's. Go figure.

Depending on your rifle, I have found 82 - 85 gr of IMR-7828 to work very well with 180 gr bullets. I have used mainly the Hornady Interlock, Speer Grand Slam and Mag Tip, and Nosler Partition, and they all shot under an inch in every gun I tried withthis load. Of course, your mileage may vary and start low and work up. I have found a wide variation in what loads would cause excess pressure in various rifles, particularly custom ones, in this caliber.

My weatherby sure likes I7828. One hint. The load I now use is a load I almost bypassed because it shot 1.5" at 100 yds. The load is a 180 barnes xbt that I moly coat myself over a max load of 7828. I'm dieing to try the new tsx as I think it will be wonderful. ANYHOW--the bottom line is I've come to believe that the 300 wby shouldn't even be tested at 100yds. I do all my testing at 300 yds as that same load that does 1.5" at 100 does about 3-3.25" at 300 yds. With a 10 power scope (and I'm not a benchrest shooter) I don't think I can do much better. Those groups are nice and round which means the bullet is not landing more than 1.5-2" from where my crosshair are centered and I've come to believe I will probably not shoot any better than that in the field. Bottom line in my book--a 300 wby should be zero'd at 300 yds for most hunting--that's the place to test it and you might be surprised by some of your "sleeper" loads.

mine likes 80 grns 4831 with a 200 grn hornady

I found that the Nosler 200 gr. Accubond, with a max charge of Reloader 22, gives the best accuracy in my 300 Weatherby (a Remington 700). I use Remington brass and Federal 215 primers.

Thanks a lot to all of you guys, now I've some input for work in my reloading area durin' Xmas vacation.

Have a great shooting new year, thanks again

I agree with Calif Hunter...I use IMR 7828, 84.5 gr. with a
180 grain bullet, Fed 215 primers of course. IMR 7828 has
worked the best for me & I've tried all suitable other
powders.

My .300 Weatherby was almost rebarrelled before I tried some plain old 165 gr X bullets that my Husqvarna .30/06 wouldn't shoot. 91.0 grains of H-1000 and the 165 X is the only combination that consistently bests 1.5" groups at 100 yards. The 165 X bullet has proven a great performer on game. Two elk, one black bear and one boar at about 300 pounds were all put down quickly. Ed
