I saved a lot of the data from the 300 and 405 grain "bulk bullets" from midway. I'll post when I get home. Cold mentioned in the AR variants section that they're switching to a new style/server or something to take care of the problems but it will take a while. I'm not sure how long a while is, but normally with IT and internet stuff its a priority and a while is only a few days. So I'm hoping that maybe by the weekend it'll be back up. |

in addition to the charts posted above here are three loads I saved from various threads at 458socomforums.com
Oh Boy..........I think I found my go to load. 1 big hole at 25yd. to get a zero.
100yds.2in. using a holosight.I loaded... 40.0grs. H4198, 2.158 oal. Hornady.458FTX 325 grain. I'm loading the Remington 405gr bullets seated so that the cannelure aligns with the case mouth.
My COL is just under 2.18". The case I just miked was at 2.175". They are charged with 35gr RL-7 and cycle fine with no signs of excess pressure. I have fired that load through the same brass about 4 times so far. Hornady 300gr JHP
34.5 gr H110 CCI 350 pr 2.005 oal group size.770" @100yds. |

According to Dave Fortier's reloading data with Lil Gun:
405 Remy fp 29 grains 2.080 oal 300 Remy jhp 35 grains 2.020 oal 300 Barnes X 33 grains 2.260 oal If you have the ability to compare the case volume under the bullet of any of these three to the FTX load, this should give you a place to start. Depending on your oal, I would start around 30 grains and work up. |

loading 32gr of WW296 with an oal of 2.200. Velocity is around 1850 fps if I remember correctly with no pressure signs and 100% weapon function. This is with a 17" barrel. Groups are running 1.5" at 100 yds.These loads work for ME in MY weapon. Use at your own risk.

Nice pics. Those were shot 100 yards into 18" of wet phone book and went through 15" to 16"

lol i was gonna post some of my data but it looks like I got beat to it. 
I can still contribute a bit I suppose.. 458 SOCOM 300gr Remington JHP Remington 2½ Large Pistol Primers 41.5gr Reloder-7 OAL: 2.08" Cycles, no high pressure signs, velocities were above 1760fps Reloder-7 seems to yield lower velocities when compared to other powders, but it does allow for a complete case fill. 458 SOCOM 500gr Hornady DGS Remington 2½ Large Pistol Primers 23.7gr-26gr Reloder-7 OAL: 2.250" 23.7gr charge has very light recoil but still cycles. 26gr felt more stout but did not produce any high pressure signs. I suspect velocity is just under the supersonic threshhold for the 23.7gr charge and a bit faster than 1200fps for the 26gr charge. |
