I was visiting with a friend Monday. He was almost out of H4350 so he picked up a pound of 4451 to try in his 6.5 Creed.
The same excellent accuracy, and it had less of a speed drop shooting down to 12 degrees for him.
I have a couple pounds of H4350 left for my 7-08s and am thinking about trying the 4451, but I know they love H4895 so maybe I'll just stay with that...
My long winded way of saying another suggestion for IMR 4451. I agree. I'll also suggest to all you creedmoor shooters to switch to 4451... 
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

In playing with my new 6.5 Creedmoor I wanted to try H4350 as it had all the buzz. I eventually found a pound. What I have experienced is that RL17 provides better accuracy and slightly more velocity. RL16 provides equal accuracy and much greater velocity. RL16 is also very consistent from 70 to 12 deg. I no longer care if H4350 is available. Amen brother. I heard RL16 is good from -320 degrees to 560 degrees. You guys make the switch to that powder, it's damn good chit maynard...

NOT Is that the eight pound jug I traded you for 231? YEP

Are you guys just switching over using your same weights, or are you working up loads? Captdavid

I started using 4451 pretty early on, at first getting three pounds for testing, then liking it enough to buy an 8-pounder maybe 6-8 months later.
There was a little difference in burn-rate between the two batches, not uncommon in new powders, enough to result in about 50 fps difference in .257 Roberts loads with 100-grain bullets. I eventually mixed the two batches, resulting in velocities about 10-15 fps less than with the unmixed 8-pounder.
This mixed 4451 turned out to be slightly faster than what's left of my last batch of H4350, but not much. A good example is my Kilimanjaro 7x57, where I loaded 46.0 grains of H4350 with 160-grain Sierra GameKings for right around 2700 fps. Had to drop the charge with 4451 to 45.5 grains to match that.
Have had similar results so far in other rounds, so obviously the two powders are so close in burn-rate that different lots would probably overlap.

Lots of good powders out there, it's hard to try something else when the powder I'm using is sub MOA.

Well, how did the H4350 vs. IMR4451 turn out? I am in need of 4350 and its not easy to find! I am trying to sort out several different calibers, searching for the perfect recipe. At the moment, it is a short bbl 7mm-08 and then its off to a 338-06. The 4350 has always been a good baseline to start from! I am interested in the results you have with 4451 as this could be a real game changer!

Where is all the H4350?
My 30.06 will put 3 165gr Accubonds into one ragged hole at 2,875 fps with it.
I had 2 lbs on backorder at cabelas. They cancelled my order without letting me know. But now they show it as not available to order, period. Nobody else has it either(locally or online that I can find). Seems like pretty much every other powder made(ever Ramshot!)can be found somewhere.
Is it all going to the military or what?
Leftybolt I bought four pounders in the last month here locally. LGS powder guy said be vigilant and buy when you can. I almost decided to switch to 4451 but actually, who can guarantee that powder will not experience any shortages either?

Unless you are running low and none can be found...  I'm getting down there on my H4350, I may be looking into some of the substitutes.  JB's posts have me interested in that 4451...

A powder dealer reserved 5 tables at our gun show coming up this weekend. I asked about H4350 and he said he has it and he has 8 pounders. He's holding 2 for me...should keep me for a while. Maybe it's becoming more available.

Last week, I picked up a few pounds of 4350. They get it in somewhat regularly and have an 8#er reserved when they get it again. Should hold me over for a while.
I did try a few pet loads with 4451, wasn't overly impressed, but i'll keep working with it. Did have a few decent groups, but nothing like 4350. I'll keep testing and see what happens. Most elevation was good which I like, just more windage than usual, but might have been me or the wind...

Not 4350 ,but I have found some of my best loads when I had to switch components against my will. The shortages caused a lot of problems with some of my regular powder supplies. I improvised a few loads and found some better loads in the process.
I have purposely never tried H4350 in my .260, 7x57 and .243 because it is so hard to get here.
