Is there a reason you want to run the lighter bullet's ? with a caliber that shines with the 210/215gr pill's.
But with sup 780-71.0 to 75gr
H-4350-66 to 71gr
Some where in there you will find what your looking for. But in my opinion H-1000 is pretty tough to beat in the 300wm casing even with the lighter 180's.
Let us know what you find, its always nice to read about guy's playing with the venerable 300 win mag and their proven result's.

Cheers and always play safe.......
 
My go to powder for the 300 win is H1000, with bullets 180 and up. A current one that I'm playing with doesn't seem to like the 210s and 208s much, but settles right in with 180s and 190s. 79-81 grains across several rifles .
 
hi guys thanks , so much work and cant finde H1000 in my area i got some 7828 so i loded 50 r at 72 gr-180 gr projectiles will let you know how it does .LR 300 mag to answer your question is i was going to use 180 gr for hunting to s i like to get same load.
 
Ok r HR at the range and not much luck .IMR7828 with 180 partition spritzer 1 moa @ 100 m but not consistent .same load with nobler accubond 1-moa but same not consistent .same powder for honesty match 2 rounds same hole then all over . Then180gr sst hornady was better with 3100GPS but again not consistent .will try different load .for 308 I used IMR4064 ,39.5gr,178gr TBHP hornady was great in CZ tactical 1:10 twist heavy barrel I was getting under 1/2 moa C.O.L.2.810. Case length was 2.010.

For a 180gr you could go with 73gr of IMR 4831 and a magnum primer. That is a max load so you should work up but it should prove to be safe in most any rifle.

What 210 are you trying to run? I found that they were too long for a standard length mag box as the OAL wanted to be out there around 3.8". After I extended my mag box I would seat Bergers and AMaxs out to where I wanted them.

Unless you're really pushing the distance then I don't see much if any benefit of going heavier than a 200 grain bullet. Even a 180 should be more than adequate given the construction of premium bullets available on the market today unless you're going after something incredibly tough and, for the life of me, I can't think of a situation where a 200gr Swift A-Frame would leave me wanting more.
 
Hercules (Alliant) RX22 has always worked well for me in my ancient black Zytel stocked Ruger M77 MKII All-Weather in 300 Win Mag.
This gun delivers sub MOA 3-shot groups and the barrel isn't even free floated.
Don't know if Alliant still makes this powder but we still have several canisters in stock at our place.

Just facts of life for a reloader. Every rifle I have ever owned "liked" its own particular load and hated others. Only experimentation will tell you what your gun likes best.

I'm not surprised at all. Typical, ordinary factory ammo is a simple flat-based cup-and-core bullet at standard velocity that will tend to shoot well in just about anything at close range. They are very forgiving about distance to lands. They could have gone back a step and made them all round-nose but the market decided they didn't want them.

The more you vary from that simple path to marketing success the touchier the load gets and the more it is better suited to the handloading market. Even putting a simple boat-tail on a bullet makes it harder to get to shoot. A more complex premium hunting bullet might give up something in accuracy; hunters used to accept that as a matter of course for sometimes needed advances in terminal ballistics. Long range target shooters would cheerfully play with their loads for improvements in exterior ballistics.

In the meantime, the one size fits most was sitting there the whole time.
