.458 Socom Load Data Needed

[IndyGunworks]

like it says... post YOUR results, post a LINK to somwhere where someone has posted load data or a website or anything....

namely info for a 325 grain bullet.... or even better if its for a leverrevolution round.

and i REALLY would like to see somewhere where someone tried to load .458 socom with large rifle primers....

will be shooting my newly built savage bolt gun in .458 bfg on monday and have waited until the last minute to find some data.

.458 SOCOM Reload Data - AR15.COM

still looking for info specific to my bullet and something with large rifle primers.

hey, at least you went through the effort to find something.

im still looking. i never thought it would be this hard to find load data on anything. im sure we will find somthing by monday

The vast majority of the load data was posted on the 458 SOCOM website. Over the years, there has been at least three different sites, the data seems to have been lost over each "update". The site is currently down again.

I've got all of it - other than the last few months.

Most of it isn't going to be terribly relevant for your bolt gun, but it will give you some good starting loads.

Large rifle primers is all I've ever used in the SOCOM cases. Machine your primer pockets to the correct depth using a Sinclair or other trusted supplier(s) primer pocket uniformer/cutter.

just read this post, dont have any exp with the rounds, but you know its probably not good when google puts this post at #3 in the search results.

good luck with the search, and ill let you know if i come across anything.

any data for hodgon lil gun? all i need is a basic starting load.

 

[aclark]

after doing a little more searching I came up with this, but not much else. 458socom.com forums are down, which is where a lot of people were being directed.

Where can I find load data?
Right now, the best place is to Email us at TeppoJutsu@ev1.net however we hope to post it on our website soon.

lagged out, dbl post...

 

[IndyGunworks]

i emailed him and he never emailed me back.... all i need is a starting charge for lil gun with a 326 grain bullet.... only have 50 of them so unless i find data i may be hurting trying to work up a really good load trying to conserve ammo

 

[IndyGunworks]

I THINK I FOUND SOME.... dont take my word for it, but just so its written down SOMEWHERE.... i think my starting load is going to be 32 grains.... work up in .3 grain incriments and ill find my max tomorrow.... then ill back it down for accuracy.... i think i just saved myself half my ammo!!!!!
thanks for the help vette and aclark.

where did you end up finding it just out of curiousity.

haha... i did a burn rate comparison with h110 and lil gun....... then i looked at all the h110 load data from the link ar15.com link and found one or two lilgun stats and compared them... they werent for my bullet weight but after looking at all the information i figure that 33 grains is a safe starting area.... really i should start with 30 but this is a bolt action and my bullets will be seated longer than they typical 458 so i think i am ok starting with 33 grains.

Could you arrange to post this data you have compiled? Available data is pretty scarce.

I e-mailed them & Marty sent me all the reloading data that he had, took him a couple of days to get back to me, though.
If anybody wants the data, PM your e-mail addy & I'll get it to you.
Also, the ballistics are similar to 45/70 Gov

Really doesn't matter how old it is.
I've already sent the data out to one person already.....if it helps somebody out, then it's worth it!

Well, I'm new to this 458 socom stuff. Ordered mine yesterday so maybe next week. They say the rifle is in stock for immediate shipment. Maybe next week. Ordered it from Class 3.
I am not new to large slow bullets or not so slow bullets, as the case may be.
I have shot wild hogs with 45/70 factory 405 grain Remngton loads out of Shikari single shot and f/u shots would have been a comfort. I have also played with 416 Remington using cast bullets and have a couple hundred rounds of 416 Rigby behind me. (recoil enters a new age). I shot a 9'5" Alaskan Brown with the Ruger 416 Rigby in 2001 and don't feel that it was too much gun. He didn't blow up like a prairie dog. Having said all that I feel that the Socom would be more than adequate and am planning black bear hunt in the spring if all goes well.
I have shot cast bullets in 45/70, 43 Spanish,and 11mm Mauser as well as various pistol cartridgers and I feel sure that a handloader could cast many of the conventional 458 cast bullets with good results.
