Favorite powder for 300 win?

[DXHI]

Looking to shoot 180 grain pills out of 28" barrel.
Was going to see what the consensus was.

H1000 for 180gr+ is my preference. If for some reason I can't make that work then I try Reloader 22.

H1000 has worked great for me, but I used it with 215 Bergers.

You should take a look at h4831sc for anything in the 180 range. Especially for a hunting load.

Reloader 22 has been my go to powder w/300 win mag's.

Very temp sensitive but I have found it to be very user friendly when finding a load. Good velocity to boot.

H1000 has worked great for me, but I used it with 215 Bergers.

That is the well known winning combo for this cartridge, right about 3,000 fps depending on your barrel, but most likely a little over 3k with a 28" tube. Depending on your rifle you should end up 75-77 grains, work up to it.

With 180 gr bullets I always found that IMR 7828 was the ticket, that is till I tried RL-26. Great accuracy and gained about 85 ft/sec. Only problem is to find some.

 

[Dosh]

H1000, but 210 or 215 Bergers.

 

[WeiserBucks]

H1000 and 215s

H1000 with the 215 Berger. And h4831sc with Hammer 181 hunter bullets.

I used RL26 with 215gn Bergers at about 3050fps but just recently ran out of them. They shot extremely well through a PacNor 28", 1-9t barrel. I was using 75gn's with a BR2 primer and OAL of 3.7350". Base to ogive works out to 2.9720" (if I'm reading my notes right).
I did try a couple 3 shot groups using the 212gn ELD-X while developing the load for the Bergers and they shot just as good if not better. Groups were one ragged hole with both bullets but the ES/SD was lower for the Hornady's, same case, powder load and primer. I could tell by the way the ELD's were chambering though that they were getting jammed but the numbers (ES/SD) were in the single digits!
Doesn't hurt that I just bought 4 boxes of 212's and a box of 200gn -X's from a friend for $80! He got them for his Bergara .30-06 but said they kicked too bad. You know I ragged him about that (after the deal of course).
In the past, shooting 180-190's, I've had good luck with RL22, IMR 7828, H1000 and IMR4831. All were good but I'd give the accuracy edge to H1000 (especially with 190gn SMK's) in my rifle, which was a stock Savage 112BVSS.
