45 Super and Accurate No 9

[Alaska]

45 Super
AA9 using CCI 350
250gr Hardcast RNFP

Anyone used this for 1075fps to 1125 fps ?
Have some loads ready to cronograph!
13.0 / 12.5 / 12.0
WW 45 ACP brass with CCI 350
I expect to hit my target velocity between 12.0 and 13.0 in 5.2” KKM G21.

Back from cronograph today at range !
My 45 ACP +P to 45 Super load data with AA9.

G21 Gen 4
5.2” KKM
22 pound spring
Wolff Extra Power Magazine Springs
Leupold DPP

250gr Rim Rock RNFP .451” Top Shelf
1.200”
CCI 350 Primers
Starline 45 ACP Nickle Brass
Lee Factory Crimp
AA-9
12.0 - 998 FPS 552FPE ( 45 ACP +P)
12.5 - 1065 FPS 629FPE ( 45 Super )
13.0- 1114 FPS 688FPE ( 45 Super +P)

The 13.0 as expected of AA9 will be my Bear Defense load in Alaska. No malfunctions with all 3 powder charges from 45 ACP+P to 45 Super +P. No Pressure signs on brass excellent ! No difference between Winchester 45 ACP brass and Starline Nickle 45 ACP brass no case expansion !
Really like this Accurate No 9 in 45 Super just takes a tad more powder to reach same velocity as Longshot. In the 5.2” KKM I think I will stay with AA9 and the 250gr in the 45 Super. Now my 3rd year with 45 Super move over 10mm . The one thing I noticed how clean the inside of the cases were probably aided by the excellent CCI 350 primer using AA9.

FYI : Max case expansion is .481” don’t go past this ! All loads here showed no pressure signs on brass at these powder charge 12.0 thru 13.0 in 5.2” KKM barrel using regular 45 ACP brass. KKM Barrel have a great case support barrel. I would expect the 13.0 load in the 4.6” KKM barrel length velocity would fall directly into 45 Super advertised velocity of 1075fps. . I really think the 5.2” KKM barrel length and slower AA9 powder with the CCI 350 is a great combination for 45 Super with the 250/255gr bullets for a trail load.

Excellent!

I use AA#9 in my warm 45 Colt loads with good results. 250gr XTP or 240gr XTP Mag gets me about 1700 fps from my Henry lever rifle. Good deer medicine.

2 great bullets
also in the 45 Super especially the 250gr XTP.
Used the 240 XTP MAG for years in a sabot with the Knight MK85 Predator muzzleloader shot a few deer with that bullet 100% penetration never did recover a bullet.
