Default OFFICAL 458 Socom reloading thread!

Finally bought an RRA CAR upper and now I need some loads! So I thought I would start thread. I am going to post all the info I have saved off other forums and hopefully we can get some 458 Socom reloaders here.

Use loads at your own risk!! I have not personally used these yet!

Barnes 600 gr RN

bullet is 1.600" long
RE7 22gr
OAL with the 600 gr RN is 2.255


525gr pile driver with gas check. 540gr total

RE-7 24.6gr
CCI 350 Primer
OAL 2.085
Very light crimp (LEE FCD)

Velocity:
1. 1079 fps
2. 1074 fps

Avg. 1076 fps

Notes: Recoil NOT harsh, good hard “push”.


RE-7 26.0 grs.
CCI 350 Primer
OAL 2.085
Very light crimp (LEE FCD)

Velocity:
1. 1140 fps
2. 1142 fps
3. 1151 fps

Avg. 1144 fps

Notes: Noticeably “sharp” recoil impulse compared to lighter load.

So far the most accurate load is...

IMR4198 25.2gr
CCI 350
No crimp
OAL=2.125


BERRY 350 GR COPPER PLATED BULLET

LIL GUN
28grs
OAL 2.085 MAX

H110
29gr
OAL 2.085
SHOT GROUP 3 INCHES AT 50 YRDS

IMR 4198
34grs.
OAL 2.085.
SHOT GROUP 1-2 INCHES AT 50 YRDS
