I want to shoot subsonic at about 850 fps.

Would someone please discuss the 458 SOCOM round? Is it being widely accepted? Does it have a future? Any experience with reloading it?

Thanks for any help…

Henry

The advantage of the 458SOCOM is that it fits and functions in an M16 based rifle.And it has loads equivalent to the typical 45-70 factory loads ! So if you like the M16 and 45-70 to make big holes ,that's it !

Thanks, Mete. I know that it’s been tested as low as 1000fps, presumably for quiet shooting against sentries. Do you know anyone who is handloading it?

I'll check ammoguide for you.

Is this going to be in a short magazine? If no, you can seat your bullets out a long ways. Are you looking for heavy or light bullets going slow? You could probably get the Ranger Rick 720 grain cast bullet moving real, real slow, but it would hit hard.

I found a load of a 550 grain Woodleigh going 920 fps. You could probably get just the velocity you want out of the 600 grain Barnes Original.

4th from left is 458 Socom with 600 grain bullet @ 900 fps, but I don't know the load data, sorry.

Thanks for all the work, Tyler.

I hope to rebarrel a cheap 7mm Mauser I just bought for $120 with a $70 Midway barrel blank in either 45ACP or 458SOCOM. Thanks to you, the SOCOM is looking better and better. The 458SOCOM was developed out of a need of the Special Forces. It feeds really well in full-auto M16’s, so should feed fine in bolt action.

The barrel reamers are still hard to find, as this round is so new. But I think I’ve found a couple of gunsmiths who might do it for me. I think the 7mm Mauser magazine will even work without modification.

Here is my $120 Mauser

Marty invented the round. He can supply load data and answer any of your questions. Sportsmans in Conroe Texas does chambering.

Thanks, Delloro.

These pictures are from the Seller at Gunbroker, and the rifle itself is still in transit. I have a five-day no-fault right of inspection, so if anyone thinks I’m crazy, please comment. I don’t know much about the rifle, so if anyone recognizes its heritage, I would appreciate knowing that, too.

As stated previously, I plan to have it rebarreled in the 458SOCOM, the center three rounds in Tyler’s picture above. I will never shoot it much above 1,000 fps, but I’ll be using maybe 500 gr bullets.

What is the parent case.

Sorry, Lyle. It is 7mm Mauser.

If you are asking about the parent of the 458 SOCOM, .425 Westley Richards is the proper base and rim diameter. You could use 50 Beowulf brass but the rim is a bit small.
Starline make the proper headstamped brass.

You can cut the rim off of Starline 50 Alaskan brass, cut the head and extractor dimension to your specification, trim up a bit - and one pass through a SOCOM sizer die will form the case.

348 Winchester brass will work as well, but requires a bit of fireforming due to the taper of the case.

Maybe a new interest for me today, maybe an Encore.......r in s.

I was playing with the Alaskan brass in an effort to make the cartridge work with the Encore extractor.

I've got a barrel made and chambered, just need to send it somewhere to have the barrel hanger/recoil lug and forend stud put on.

In my stumbling around in “gunstock duplicators†recently, I discovered that, when duplicating a violin or cello they use hot-melt glue to hold the raw wood blank in place. A machinist friend of mine also sometimes uses a similar compound for holding metal parts down during milling operations.

So, am I a heretic for suggesting that, after bedding, a hot-melt glue compound be used to attach the action to the stock? Seems to me this would provide a superior attachment between the stock and action, especially for actions with lots of surface area.

Those parts need welded on, not hot-glued.

Let's just pretend I never suggested the hot glue. I could not find the stuff I saw being used for fixturing in that machine shop anyway.

Can someone tell me what the other cartridges are in the pic? I got that the middle three are 458 socom, but what about the others?

Andy

If you deside to go with it, I have a supply of .425 WR cases that I used for a wildcat. Let me know and we'll work something out. If you don't have initial feed challanges I'd be surprised roger

The 3 on the right are the 500 Phantom (based on shortened 500 Jeffery)
The 3 on the left might be 338 Spectre or 358 CQB.(not sure, never saw either one)(parents 10 MM Mag and 30 Rem.)

GLZ,

Thanks, but the "three" on the left are two different cartridges... I assume you were talking about the 2nd and 3rd from left?

I can't count, just glad I got left and right correct.

Well, I guess I’ve fallen off the 458SOCOM bandwagon, at least for now. I’m opting to rebarrel my 7mm Spanish Mauser in 45ACP. Hope to use a 1/16 twist 26†barrel.

My thanks to all who contributed to my knowledge.
