Lt-32 powder in a AR-15 .223/5.56

[Muzzlestuffer]

Anyone using lt-32 for ar-15 loads ? I had some I loaded up back in 2013 19 grs lt-32 under a 69 grain matchburner went to the range last week and shot a one hole group at 100 yds and 2-1/2" at 200 yds out of my ruger sr556-vt i think I can get better groups but my scope is a Leupold ar scope with the mil-dot reticle but it's hard to get precise with that reticle I much prefer a Leupold small dot reticle for precision aiming. I also loaded another batch last night along with some at 19.5 and 20 grs headed to range tomorrow I also put a light taper crimp on these would be interested in hearing from anyone using these loads.
Thanks

Got good results with it in a WOA Match upper. Did a spread around an estimated 2900 fps with 52 gr SMK, 20-22 grs IIRC.

Sub MOA for every charge I tried, I've never seen anything that consistent. Best were around in the high 0.5" region. For some reason, I never went back to refine it. It is on my to-do list.Never worked with any heavier bullets.

I just swapped out scopes put a varix-3 4.5-14x50 with a dot reticle on it that will help my groups !

My shootin bud just gave me a partial jug. High praise, havent tried it yet. This is encouraging.

You'll like it and the really good thing is you can almost always get it !

Went to range today but pretty windy shot some groups at 100 yards with the different scope definitely better ! Tried bunch of different rounds and bullet weights I loaded up some .69 grain matchburner over 19.5 grains Lt-32 I like them better than the 19.0 grain loads but will need to do some more testing with less wind next time out.

Following your adventures with the heavier bullets, keep us posted

23.7gr LT-32 behind Berger 52gr match bullets with Lapua brass and CCI BR-4 primers are super accurate. YMMV but hard to go wrong with these components. As always, work up to max book loads, which this is.

Lt32 and 133 are perfect for around a 52-55gr. Its too fast imo for anything heavier. I suggest n135

I dont have any n130 and dont plan on getting any more powders I already have too many besides if I can get 3 shot one inch groups at a 100 yards and two inch groups at 200 that's good enough for my purposes with this ruger sr556-Vt platform.
