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 http://i.imgur.com/kibom.jpg |

Thanks. I don't have a thumper yet, but after looking at the Beowulf, Bushmaster, and SOCOM, I keep leaning towards SOCOM.

I have a barrel on order from wilson combat. Also some brass and dies on the way. So I am glad to see this thread start. I will definitely post up once I get some loads made and tested.
Noah Also anyone who has ordered the lee fc die.. I was wondering if it matters what bullet the dummy has seated in it? What exactly is lee looking at when you send them the dummy? If it just the trim length of the brass? Anything else? |
Best deal on bullets I can find are the Berrys 350gr platted and the 405gr gas checked. I am still trying to find some load data for the 405gr gas checked.
Anyone have any tips/info on coming up with your own load data. Starting powder / OAL etc? |

Just got started
Reloaded SBR brass cases this weekend.
WLP primers 300 gr Sierra JHP 30 gr Lil' Gun Then tried another batch with 31.2 gr Lil' Gun All expended cases looked OK, but I had a bit of trouble getting consistent seating and correct OAL, especially with the first batch. Seating too deep definitely increases pressures. Worst case was one with 30 gr Lil' Gun, with OAL 1.994. Primer was flat but the case looked OK. Groups were marginal (about 4"), I assume largely due to the different seating depths. A few questions for the pro's and gurus here: I'm using Redding dies. I couldn't get consistent seat depths. (+/-0.020") Can you get different seating inserts for the dies ? Am I better off with different projectiles ? The soft lead of the exposed JHP tips may have imperfections or diameter variation. I could see a definite firing pin imprint after rounds were chambered. Are CCI350's harder than WLP ? Anyone have a favorite primer recommendation for this round ? Is there a bullet puller that works with the reduced base dia. of this round ? Mine can't grip them. Thanks in advance for any help ! |

Noah P.S. I am not sure if you are already aware, but I understand that if you are seeing pressure signs like the flatened primers then you have exceeded the max pressure of the .458 socom. Warning for any who are unaware: The .458 socom is designed to be a relatively low pressure and has some unique issues when hand loading. I was totally unaware of this until I really started searching out load data online, and came across several experianced .458s guys urging caution. A couple of quotes that stuck out to me. Quote:

I keep reading that the 458S shoots up to 600gr bullets. Anyone have a source for 600gr bullets? I cant find any. :(
|
Barnes made a 600gr in the barnes "Original"... however I do not see it listed on their webpage, possibly it has been discontinued. MidwayUSA has a few 550s.
I haven't seen any 600s on the sites I buy components from. I would think a hard cast 600 should be available somewhere but I don't see any when I search. Noah |
What do you guys think about cast bullets? Gas checks or no? I am thinking about giving the LAsercast bullets a try.
http://www.laser-cast.com/AboutLaserCast.html As always, your satisfaction GUARANTEED or you money back No leading Slick Silver Bearing Alloy yields highest velocities of all Extreme accuracy |
Their 405gr looks like a winner for larger game(butte county bears). Their prices look great too if their special alloy lives up to the hardness claims and lack of leading. Thanks for the link, I plan on putting plenty of lead through mine.
Are there any special issues/considerations with the .459 diameter? |

Speaking of bears we have them getting in our trash constantly... |
Quinc,
Can you expand on what you know about .458 vs .459. I need to put in a call to Wilson Combat and find out how closely their specs are to a Marty barrel vs a RRA. Do you know where the differences are? Is it just in the chamber, or the bore, or both? I would really like to give those 405s a try but don't want any issues. I am guessing they will fire through a Marty barrel just at the risk of bumping up to higher/unsafe pressures? Noah P.S. Sorry to hear about your bear trouble, It has been a bad year for that with the poor snow pack. Luckily we are low enough in elevation that we don't see them around our place... have had a few incidents from our friendly neighborhood mountian lion though. |
I've read on a couple different forums about the teppo uppers being cut tighter at exactly .458 and the RRA uppers being at .459. I will post more info if I come across the threads again.

Update for socom reloaders:
LEE Factory Crimp Die is no longer a custom order item. Its not in their catalog but can be found here for $25. http://leeprecision.com/458-socom-cu...crimp-die.html |
I've been looking into the Wilson Setup. I really like the 14.7 inch setup. How many rounds are you fitting into a 10 round (or 10/30) Mag? I think the standard mag is 7 or 8 ?
|
You can get about 3-4 in a 10 round mag, and 9-10 in a 30 round mag.

per wilsons web site "Temporarily Out of Stock, Expected 11/15/12" I have been waiting on my order since july. If you are serious I wouldn't wait. Last time I spoke with someone at wilson they said getting barrel blanks was not easy for them as the industry is totally swampped, and I am sure it will only get worse. The kits to build yourself are pretty reasonable price wise. |

I loaded some test loads for my Wilson Combat 458 SOCOM and had a chance to test them out last weekend. Specs are below:
Starline brass CCI350 Primers Hornady 325gr FTX bullets Hodgdons H110 powder COAL 2.25 Loaded 45 rounds in sets of 5 from 29.0 grains to 33.0 grains in 0.5 grain increments. I didn't see any pressure signs until I started shooting the 32.0 grain rounds. I stopped at 32.5 grains of powder. The 31.0 grain loads seemed to give me the best accuracy (1 1/2" group), with no pressure signs, and chronographed at 1690 fps. I'm still perfecting this load, so my next step will be to load up some more in 0.2 garin increments starting at 30.0 grains to 32.0 grains, but will seat down to 2.230" COAL. |

rudynix,
What length barrel do you have? and have you had to make any adjustment to the gas block on that WC setup? Noah ps. careful with your pressure, sounds like those 32+ loads may be really hot. |
Quote:

Cool, I saw the pics of your WC setup in another thread... Very nice, I hope my build will come out half as good as your upper.
Anyways, I am getting ready to start working up some loads as well(been waiting 7 mo for my WC barrel and upper, It shipped last friday so I should have it any day now). So I am glad to see some activity in this thread I will post up my load recipies as soon as I start. I will probably be starting with lilgun so hopefully this thread will grow more from here on out. Happy shootin' Noah |

I got my 458 Socom bolt Microslicked from the vendor here gregchico. You guys might want to check into it. It also really helps with cleaning! :D

Quinc, I see that the microslick vendors name is gregchico, is that gregchico as in Chico.... local, no shipping? |

OK so here are my first loads I have put togeather this mourning.
Not sure what day I will make it out with the chrono to test them. This is my first time loading a round that isn't in any of my loading manuals so I would appriciate if others would give them a look over and make sure nothing looks out of wack.

Anyone?
... also if anyone knows where I might find some bullets in stock online... I have tried midway, cabellas, CtD, and several others that google offered up.... everywhere is out of stock of the TTSX and other popular socom bullets. Thanks Noah |

Hi guys. I'm the new kid on the block. I ordered a 458 upper from RRA last month and I'm not so patiently waiting for it to ship. I don't suppose any of you know typical time frames at this time? I did see Quinc post his 2 month, but I've also seen 6 month posts. I suck at waiting, lol. I am also new to the world of reloading as I can't afford $3 a round prices on my beer budget. Best places to get supplies? I have a Lee single stage press and a scale, but will need the dies, brass, bullets, primers, and powder. I have a buddy that I'm gonna get to train me and he can probably help with most of that, but anything specific to 458 seems to be hard to find in bulk. Sorry for the novel and thanks for any assistance.

mach1269,
be sure to get a loading manual. It wont have 458 socom recipes in it but it will have all of the fundamental process step for reloading and is a must have. Also you will need a tumbler to clean your brass. I recomend Imperial sizing wax for resizing lube on the socom, the brass needs a good full lube job to be sure you dont get a case stuck in the resizing die. You will also need some other basic case prep tools for trimming to length, chamfering, beburring, etc. As far as supplies, you wont find many bullets in bulk quantities for the 458 caliber other than cast lead and maybe some basic hollow points. As far as where to get stuff I usually use Midway, but there are many choices online if you can't find stuff local. Cabellas, cheaper than dirt, etc. Don't worry about getting everything asap cuz you will be waiting a while for that RRA. The industry is slammed right now and I have heard manufacturers are having a very difficult time getting 458 barrel blanks. I ordered mine before the panic and still waited over 6 months. Good luck with everything and be sure to get plenty familiar with the reloading process with your buddy on some more common rounds before you start working on socom loads. Noah |
Also get yourself a Lee Factory crimp die. It is the only way to go with many of the bullets where you cannot seat to the crimp groove of the bullet
|
Thanks Noah. I was afraid I was going to be hearing 6 month+, but hoped for better news. I will get plenty of practice on reloads as I will be getting stuff for my 375 Mag, Glock 23, and I am looking at getting a 1911 because I've alwayswanted one. My wife is getting in the game now too, so I'm looking for a purse carry for her. Probably want to stay in .40 to keep ammo variety to a min. At least until I get proficient enough to justify spending on a higher end reloader.
|
I bought a RRA carbine 458Socom upper 2 weeks ago. Placed an order with two businesses for ammo. After waiting 2 weeks, both backordered the ammo with no ETA for future stock. So now I have the upper, but nothing to shoot through it. <sigh> I've shopped for brass and bullets to reload my own and no luck their either. This is like having a monster truck but no fuel. :no:

Well, I got out to the range yesterday with my loads...
I don't have time at the moment to post all of the results but I can say one thing for sure right off the bat. My rifle sure like the LilGun over re7... big time. Velocities were much better. For example: With the 325 Hornady FTX, I could not get the re7 to even push one single bullet over 1500fps... Then my lightest load with lilgun had an average velocity of 1613... with my hotest loads pushing over 1800. I really was surprised at the results since a lot of people on the web seem to like the re7 for the socom??? Anyways, I will post up the chrony data later when I get a bit more time. Noah |
