Mag Tech 230 Gr. FMJ testing.
Posted: Sun Nov 13, 2011 9:31 pm
I am Texas Sheepdawg. My warnings are clear. I will confirm that my R&D on these rounds are pushing the envelope.
What worked in my AR15 will NOT work in your AR 15. My AR is unique. I strongly advise in all of my posts on the 230 Grain FMJ to start low at 38.0 grains of LilGun and work your load up. Know your chamber. INTIMATELY.
All of my loads were developed with the help of Timothy LeGendre almost literally looking over my shoulder.
My advice to all of you is this. Do NOT use my current R&D data for the 230 Grain FMJs for any rifle with a 1:16 twist. That data is intended ONLY for AR15s with the 1:24 TWIST.
YOU’VE BEEN ADVISED.
We had a fairly nice day today so I grabbed the gear and set up my Chrony to test some more 230 Gr. Mag Techs loads that I worked up earlier this afternoon. However, I forgot about it getting dark earlier so I think my Chrony got cranky after the first shot and only gave me errors so I stopped and will continue the tests tomorrow. Here are the results so far.

Brass- Hornady
Primers- WSR
Bullet- Mag Tech 230 Grain FMJ
COL- 2.13"
Powder 40.0 Grains Lil Gun.
