hey cgn,

so if you roll your own you'll know it's a #### show getting stuff you need

if you don't, you should start so that:

A you can have ammo that you want when you want it
B you can prolly save money these days



there are lots of questions about swapping powders
that's a bad idea as recipies are there for a reason

however if you can't find a powder you are after, you can use a burn rate chart to discover similar powders that may have receipies

I STRESS POWDERS SHOULDNT BE SWAPPED / INTERCHANGED

however there might be loads you are not aware of

we are working to have the best selection and prices available

So if times were really hurting and you need a medium burn powder could you take fast burn and buff it down with a slow burn powder and make what you need.
 
I have a similar chart but what it doesn't tell you is the actual burn rates, meaning the degree to which one powder burns in relation to another. I'm considering smokeless in my modern 45-120 and know that a slower powder is better. People recommend 4895 and 5744 but they are in the middle range so wouldn't retumbo or h-50bmg be better suited?

No. Never. Different densities will separate in the case; in the powder measure, in the can with handling. Uneven burn rates = pressure spikes..

Hodgdon recommends these, so this would be a great starting point:
Benchmark
H322
H4198
H4895
IMR 3031
IMR 4064
IMR 4895
Trail Boss
Varget
 
Be careful with substituting to achieve ballistics ! Yes you can but, going by a burn rate chart for instance is just the very "first" step in load development, I have been loading and casting since the 70s, I use "gallery loads" (reduced loads) for cost effectiveness and also experimented with "like " burnt rates to test (such as Leverevolution in place of CFE223 and varget for instance) to get maximum fps.

Position sensitive powders, reduced powder capacity, too slow a powder for case volume just to name a few...you can have a bad day if your primer flame jumps your reduced powder charge and burns from both ends or ,too slow a powder in a large case full and the primer only pushes the projectile into the rifling, now you have an obstruction and with a hang fire !you can guess what that would do!

Thank goodness for ballistic experimentation, if we didn't have people willing to test in controlled environment with great documentation and science to back it up, we would likley still playing with black powder! There is tons of good resurch and precautions on line and in loading book's.
 
Those are good powders for different applications (rifle vs pistol), but in Canada it's always been a matter of checking the reloading manual to get a list of powders that work for the calibre and bullet you're trying to reload, and then checking if hopefully one of those is actually available here.
 
I'd go with 3031, with a 45-70 and heavy bullets you just can't quite put enough in to max out, but it is still pretty good. I've used it to play with 500gr bullets that I couldn't crimp right. Just 105% load and seat hard. can't go back any farther in the case and still has respectable numbers.

Right now when you come across something you need or want you have to act fast or you'll miss out. Supply is so limited and demand is high so if you waffle over not wanting to pay the price it will be gone before you decide.
Ask me, I know.
 
Best powder advice is to ALWAYS check with a reputable reloading manual (Sierra, Hornady, Nosler etc.) They will list the powder options for a particular round.
