RL10X=speed,speed, and more speed!

I picked up a can of this stuff when it was first released about 2 years ago to try in my .223 with 40 gr. Vmax. The max load listed in the scarce loading data said 25.2 grains. I loaded up to that charge with no luck. In fact, it was the least accurate powder of 6 that I tried. So, I put it on the shelf for a few months. Then one day last year, I loaded some more up and went from 25.5 grains to 27.5 and HOLY CRAP! The groups shrank with every increase of powder until I got to 27.5 which produced 3/8" groups and average velocities of 4015 fps!! That is 200 fps more than N133 or Benchmark gave me with the same charge!
This stuff is awesome for light bullets in varmint calibers. I can't wait to try it in my 6 BR.
If you haven't tried it yet, give it a whirl. I think you will like it! [img]/ubbthreads/images/graemlins/grin.gif[/img]

FYI--RL 10X was changed somewhere in the mix--your original bottle probably isnt quite the same as the new stuff.

might call hodgedon for details.

FWIW,

So what is the burn rate supposed to be now??

I dont know that the burn rate changed much, but i think it is CLEANER burning now??

calling them now...
got voice mail, waiting for a call back!

call back...

Burn rate is unchanged, but more "decoppering agent" was added because of complaints from some point-blank BR folks.

so no worries, your load data should be ok [img]/ubbthreads/images/graemlins/wink.gif[/img]

Given safe working limits, I would expect a .223 to get about 3,800 ft/sec with a 40gr bullet. You are getting velocities that are more consistent with what you can achieve with the 22-250.

I would recommend a little caution here. [img]/ubbthreads/images/graemlins/smile.gif[/img]

Good shootin' - VH

Thanks VH, I approached this load cautiously and there was and is no pressure signs. My rifle is a CZ 527 Varmint with a 24" barrel, and it really screams! There is no heavy bolt lift and my cases still have tight primer pockets after about 14 loadings. My load is 27.5 RL10X in a winchester match prepped case with a WSR primer and a 40 grain bare Vmax. All speeds chronoed by Oeheler 35 on a 4' spacing 10' from the muzzle.
I love that RL10X!
