Title: Got powder ( tho not what I wanted )
Post by: tommac919 on October 18 2013 08:40:09 AM MDT
As most know, getting reload supplies is pretty tought these days...

Well, I obtained some Win Autocomp ( not my first choice, but sometime you take what you can get ). I see that this powder can be a bit hard for total ignition with lower loads... was wondering if some have use mag primers instead of the to cci 300  for a better burn

BTW; for a G20 with 180g.

You may have to test some because AutoComp already produces plenty gas volume.  That said small changes in charge weights may raise the pressures quickly.  I know there are some who used the AutoComp in test at GlockTalk 10mm reloading section of the forum.
Hodgdon's 2012 Annual Manual shows a few loadings for the 135,155,180 and 200 gr bullets with pressure values.

135 Nosler JHP     8.7 gr @ 1372 fps 28,400 psi and 9.5 gr @ 1476 fps 34,500 psi
155 Hornady XTP  8.0 gr @ 1254 fps 29,000 psi and 8.9 gr @ 1362 fps 36,700 psi
180 Sierra JHC     7.0 gr @ 1119 fps 29,800 psi and 7.7 gr @ 1199 fps 36,000 psi
200 Hornady FMJ  6.0 gr @  959 fps 25,900 psi and 7.0 gr @ 1100 fps 36,100 psi

Hope this helps!

p.s. Please post a good close-up picture of a small amount Auto Comp Powder in a scale pan if you can, or you can e-mail it to me if that helps!  _shadow_(at)bellsouth(dot)net  place the right symbols (@ and .) without the parentheses.  Thanks!
