RL17 - pros/cons - Temp sensitivity / throat life

[6.5BR]

Heard that this powder is less stable in higher temps, ok at normal and low temps, any word on this?

Also, throat life one person I read may have been shortened by use of RL17. Does it burn hotter? Wondering if it's true and meaningful - any difference in bbl life if used extensively?

What's the scoop/consensus on Types of powder, the heat and how that and/or size of granules affects throat/bore life?

Double Based, this, that, ball vs. stick? Anyone?

Are the differences significant or not? Thanks.

IMHO geometry behind the cartridge and the pressure it is running will burn your barrel faster than the type of powder (which I know affects pressure).

Thanks much sir.

Re: RL17 - pros/cons - Temp sensitivity / throat life

did some testing with r-17.....generally thought it ran hotter.....but and however...there also was a whole schwack of what is now percieved as BAD steel that made it to a lot of barrels....and thus via a hawkeye made a LOT of barrels look like burnt charcoal....fire cracking all the way from the throat to the muzzle....fucking FRIED,TOAST,burned the fuck out.....


me thinks the 17 was not a total culprit....but others that have played with 17 thoufgt it also ran hot

It burns hotter, longer down the tunnel. That's how it does what it does.

I hope my throat life hasn't been degraded, no signs of it yet.
I used RL17 this season. When I worked up my load in the Spring, I got decent results. Definitely the velocity I was looking for, OK SDs, good accuracy.
But, as I've used it in a number of matches where the temp swings from 55 degrees to 80 degrees, the velocity starts spiking on me at the higher temps. Where I was nailing everything when it's cool in the AM, I'm all over the place in the PM.
While I've seen others post similar experience, I know a few dedicated and well experienced LR tactical competitors that are sticking with it. I'm looking at H4350 & H4831sg myself.

K, you running a 6 or 6.5? No intention to invoke fear in those using/have used.

Thanks for replies guys.

Thought so.
