Looks like a national shortage. What's a close second for medium and magnum rifle?
My local guy just got in 6-8# & 28-1#. I went & stocked up. He sells a lot of powder, said he only sees H4350 once a year & he has a standing order for as much as they will sell him. A close 2nd would be IMR 4350. The new 4451 may be just as good but I haven't tried it yet.
I've used Viht N160 but it's pretty pricey.
RL-17 works very well and is a similar burn rate.
Years ago I had very good results with AA4350 in the 6mm Rem but today I think AA powders are made in China and may be different from the older powders.
AA powders aren't made in China. If you go to their web site, it will say where each powder is made. Their powders are made either in the USA, Canada, or Belgium.
Btw, what caliber magnum? Smaller bores usually do better with slower powders like RL22, H4831, etc. i run H4350 in my 338-06 & 260ai.
270, 30-06, 338WM. I've used it for quite awhile now, and hate to switch. Some will say there is no equal
IMR 4451 and R16/17
I really like H4350 in my 260 but ran out and tried the 4451.
It seems slightly slower than H4350.
It's only slightly more temp sensitive with equal accuracy and speed.
Really good alternative.
I like R17 but the temp swings are big enough that you will have to adjust for the verticals if shooting at long distance.
There is no equal. I was 1st.
In 270, I would run H4831sc, it's over bore & you'll get better results IMO. 06, depends on bullet wt, but yes H4350 is good there up to 180gr. In 338wm, try RL19, many like it. I run that in my 338x74K, sim powder cap. I haven't tried RL17, pretty new, or the IMR 4451, but many like them as well.
BTW, all the 8# jugs are gone at my local guys, lasted less than 6days. He still has 17-1#, down from 28. I expect those gone before Monday. I will probably regret not buying the 8# last sat.
In the 06 RL17 is super with 180gr and up.
4831 works better than 4350 in the 270 and 4831 has long been acknowledged to be the best powder for that caliber.
4350 is just right for the 30-06 unless you're loading for the Garand and 4350 is a little too fast burning for anything but 200 grain bullets in the 338.
In my opinion RL-17 is the best replacement for H4350. I also like RL-15 as an alternative to powders in the faster 4064 burn rate range
I always had good luck with IMR 4350 in the 30-06 but the IMR version is supposed to be more temperature sensitive than H4350.
I have only used IMR 4350 and all of it loaded in -06, always seemed to work great.
I couldn't get to any load data on those links, does your computer allow you to see the links?
Me being an ignorant gunsmith I am not sure now, I use to
be able to open them up but thought now you had to join or
something like that.
What the links showed was the 30-06 loaded the hi pressures
as many of the other calibers, 65,000 PSI.
With the 180gr RL 17 was the best, even with the 200gr
it was up there.
If I can find it in my mail I will try get to you.
I collect much data in my mail.
Alliant 2400 is the powder I can't seem to find locally.
Fortunately my local guy has 2400 too, 1&8#. I know that isnt helpful, but if he is getting it, someone local thete must be.
Not a problem, I just assumed was a spam blocker or some such auto feature to keep me from hurting myself on my PC..
It has been a while for me and 30-06 anyway, although I still have that old Model 70.
