Well...........

Apparently this is the best kept secret in reloading - I’m curious why I am not reading or viewing more about this powder and our favorite calibers.

I explored the possibilities with 6mm Grendel and 90 grain Speer bullets and at a modest 30 grain charge weight I am at 2875 FPS with sub .5 MOA accuracy at 100 yards.

All load manuals are void of reload data and pressure data yet you do some digging and you’ll find that people swear by this stuff.

Oh and the ONLY good thing, in my opinion, that came out of the 6mm ARC caliber launch was Hornady load data for LEVERevolution. It shows I could safely run the charge weight up to nearly 32 grains........

If you look at a powder burn rate chart, it's on the slower burning end of all the common 308 and 223 powders. It would certainly work with a compressed load if you worked up to max with it. I have a few "secret" powders I like to use for certain things also that's not in ANY reload data. If you experiment enough with certain things, you can find some hidden jewel powders.

I had some issues with it being a bit dirty in my AR's in 223 and 6.5 Grendel unless I used magnum primers and loaded to top levels. But yes plenty of performance. Love it in my bolt gun 223's running 26.0 grs under the 75 gr. Hornady BTHP match bullets and getting over 2900 fps.

I run it hard in the new 6mmARC that I built. It's good; and as a matter of fact, it's one of the best of the 4 powders I've tried as far as getting the MV goosed up, safely, a bit more..

I ran into some issues with my load combo: issues started at 31.3 grains

CCI 450 primers
31.0 - 31.9 grains of LVR (pictured below)
90 grain Speer Deep Curls

Yep! Looks like you may have hit the wall on that combination!

I’m going to rerun the same charge weights with a 90 grain Sierra game changer to see if the results are different.

There was some who attributed Speer discontinuing the Deep Curl bullets because they exhibited pressure issues with conventional load data.

Hoping to be able to get better accuracy and 2850 FPS or more from the 90 grain in a 20” 6mm AR gas gun

If the game changers show the same issue I guess I’ll try a different powder.......
