Pressure: when is too much and why?

[Tell]

Maybe so. I can’t tell you how much I’ve learned since joining, and how much of a better shooter I am now. There’s a lot of knowledge in the collective of people using this site, and I’m very thankful for it. I grew up hunting and shooting, but I was like everybody else I knew. And when I look back to even a year ago, I’m an embarrassed at how ignorant I was. The information is out there, and the people on this site have an incredible amount of experience and I’m glad they’re willing to share it.

And thank God there are different viewpoints and disagreements. It gives us all a chance to use our heads for more than just a place to hang our ears. I’ve had quite a few good disagreements at the gunsmith’s shop where a lot of great shooters and hunters are always popping in. And I know we’ve all learned from them.

I've never experienced those problems with RL26 personally. Interesting. What's not interesting is this "Jake from unkown" that knowingly produces these "super hot" loads. That guy's an idiot.

Blanket statements can send an inaccurate message as case shape and volume can alter burning rates.

An easy example may be what we call a fast (ish) powder like 4198 (any of them) which is a fast powder, relatively speaking in a straight taper case like a .45/70 or .458 Winchester and yet it becomes or is considered, a slower burning powder when consumed in say a .222 Rem or .223.Rem case.

The smaller case volume and bottle necked case design allows the powder to burn more progressively.

Tbe same thing can happen or be noticed with Rel 26 just by changing the case size and shape. I have used it in a range of cartridges including .25/06, 280AI, 7mm Rem Mag, .30/06, .338 Winchester also with a range of bullet weights for each of those cartridges and its burning characteriatics may align differently with other powders also tested at the same sessions.

It pays to chronograph all test loads and record the data. Most importantly, review and digest your results and you will notice burning characteristics that ultimately teach you about powders in general and more specifically, how they compare and relate to the carteidges you have chosen for your own use.

If you like diving deep, put your results in a simple spread sheet and also record your group sizes, velocities next to tbe loads tried.

I take pics of these pages and save them on my phone for spare time viewing and reviewing. The more detail recorded the more helpful you will find it.
