Title: Hornady's 200gn FMJ-FP + AA#7
Post by: agtman on August 13 2013 05:47:06 PM MDT
If this was answered before, I couldn't find it.

Have a G20 with an aftermarket, stock-length tube (LWD & Bar-Sto), using an ISMI 20lb recoil spring.

Want to load Hornady's 200gn FMJ-FP to max over AA#7 powder.  Have plentiful of both.  With that combo, what's a max load that people here have gotten to and are comfortable with. 11.0-11.5 grains?

I've got new brass and have lots of 1x-fired Winchester or Star-line brass.
Also have a plentiful amoun of CCI 300 Lg pistol or CCI 350 mag primers. Which do you recommend w/ this combo?

Thanks!   8)

My older Accurate Arms PDf files show 200gr FMJ using AA#7 10.7gr. @ 1144fps 36,200 psi  COL 1.2500"
However The newer data doesn't even show the FMJ or the TMJ listings.

Lyman Pistol and Revolver and Lyman #48 shows 200gr JHP over 10.6 grains of AA#7 @ 1145 fps 28,200 CUP COL 1.2500"
Speer #12 shows their 200 TMJ over 11.6 @ 1151 fps no pressure given...but said to be with in SAAMI standards.
