QL Request Grendel

[hunter24605]

Could someone run a QL model for me. I'm working on a SBR Grendel with a 12" barrel, and hoping to find a powder with 100% burnout before muzzle exit to be IR scope friendly. May be a tall order, but I think N133, N130 will do it. also looking at H335 and Benchmark.
Thanks a million!

The 115gr Tac-X isn’t in my QL library.

Ok, Thanks. I should have said TAC-TX not X, but either way it isn't in GRT either. Guess I'll have to build a bullet profile, and calibrate with a few starting loads in GRT

QL does some nifty things but how does QL tell you if you will have 101% burn rate before 12".

Truth be told you will need it to be burned up well before 12" so you don't get the flash you're trying to avoid.

That said and saying again, how can QL tell you that information. I know QL is nice and gives some data with a specific powder charge and bullet and it comes in really handy when that information is not available from publications but a burn ratio over a bbl length...

I honestly don't know enough about it so I am curious to learn what I am missing on that program

There's no completely avoiding it, but the goal is to minimize and let the flash arrestor reduce it even more. I know with the 6 ARC, I found a huge difference in IR white-out by working with powders until I found one with full burn somewhere around 2" before exit. I'd have to guess it is a math formula involving: Burn rate, powder mass, bore diameter, bullet mass/length, engraving pressure, even tweaking the twist rate will change the burnout slightly. GRT gives that information to. shows "Burnout" at X point. But, it's way more accurate when you tweak it with a few real-world loads for calibration.

I have no idea what I'm looking at there. What is GRT?
That's not Quick load.?.!

Speaking of flash hiders, I couldn't be happier with the Strike Industries Venom flash hider. It eliminates the vast majority of flash, and at $50.00 it's even more appealing...Although it does "ring" after the shot. Imagine a very faint tuning fork sound. But, living with pretty bad tinnitus, I'm pretty used to crickets and tuning forks in my head..LOL
