458 SOCOM: the journey begins!

[Rikky Lee]

Well thanks to all the discussion about the 458 SOCOM in the threads below I have had to start building one.

Have got cases, just ordered a reamer and chasing a barrel. Reloading dies and a supply of projectiles to follow.

The cases feed nicely in the AICS magazine and the Rem 700 SA.

Watch this space!

Hi,
Congratulation and good luck.
Mine might be ready by the end of the month.
Have a look on grafs.com for the dies. They sell some Lee dies for $28 which is the cheapest you will find anywhere. I paid $150 at CH4D.

Cases might be available from them as well.
Reamer from pacific tool.
Barrel from Pac-nor for exemple.
I have a 1 in 13" but most people tend to go with 1 in 14"

It must be something in the water ...I ordered a 9.3 twist from Rock Creek a few weeks back. I'd done two others prior and got rid of the AR. The Savage barrel is still around here somewhere..

Since my last effort I've acquired a 458 throating reamer and have an idea about some Lehigh brass solids that weigh 528 gr and have a calculated BC of .828

Best wishes for both your builds...be sure and post progress reports.

Far too many interesting threads on the 458 recently I think!!! not to mention that I'm loving the range of 458 projectiles already - and not yet bought any!

I'm thinking to go for an 18 - 20 inch barrel on the bolt gun.

Spook: why the 9.3 twist? More importantly - what effective range do you think we can get from the VLDs and what velocity?

ND: any differences from your perspective on the rifle twist?

What about torque at the faster twists? I'm expecting quite a twist from the rifle if I push a heavy projectile out fast.

Off to Grafs now...

Rik, Specs say 10 twist to stabilize the Lehighs but I went a little tighter ....just in case.
I'm looking for 600 yds and better with a bullet with that much BC ...1060 fps. Looking for a reason to sell my 510. The API's I was getting such a kick out of are getting hard to find in a "hand pulled" grade. The machine pulled/resized arent as accurate.

What is the advantage of the 458 over the 45-70
besides it will work in a AR platform ?

Any update on the progress of this combo? I had been looking at doing something subsonic in .510 to launch A-Max's; but since having seen pics of the big beautiful Lehigh's loaded up in 458's -I think this might be the way I go. If they would feed from a Savage centerfeed Long action that would seal the deal.

The barrel's in ,7 groove Rock Creek but beyond that ....There hasnt been enough time.

Lou Boyd can probably tell you about the loaded length and ballistics. My trying this round a third time was inspired by his pics.
I dont doubt you'd be able to seat the bullet a little deep if getting it to feed due to excess OAL is an issue.
