Which short action magnum?

I only use N540 in my hunting rifles with very low rounds, burns really hot.

I've heard of that one being really hard on throats yet by the temp ratings varget and h4895 are just a step down and they certainly get a lot of use in high volume guns.

I was under the impression the powder rate charts had to do with speed off propagation or the " burn rate" not how hot temperature wise it gets. Seems to be a known thing the V5 powders are double base and are hotter temp wise and can decrease barrel life whereas the V1 series are not. Or am I miss informed?

Correct, the chart that everyone miseads runs <Faster-Slower> It has nothing to do with burn "temperature". Like all the VV and other double-base high pressure powders, they will burn throats at an accelerated rate.

Another thing is that the chart can be quite misguiding
For example it shows that N540 is a bit slower than XBR but in Quickload and GRT it's very close (at least in Dasher/Grendel sized case).
Powder burn rates aren't linear and theres a lot of variables ( single, double base, flake, ball, granule size, density, temperature, effect when compressed, etc etc)
I'd never select a powder/charge just by looking at the chart.

Don’t worry about those RL powders for a while

The same company that is considering selling Lake City ammo to the Chechs? What a bunch of American hating, pice of shit communist they are turning out to be.

Yep, same ones

Yeah, cuz they're the only company that produce their powder with nitro lol, what a joke. If you didn't want to sell to the public, just say so, you don't have to make shit up. As if them hiking their prices weren't enough...
I bought enough of their shit when prices were ok, definitely not interested any more
