I’ve been on the fence several times about a .458 upper. The range is obviously in favor of the .458 my philosophy of use is <100 yards against vehicles and things that wold be cover with a handgun or 5.56. Capacity is a non issue as its black aces receiver custom build on Mossberg 500 SBS. Realistically the practical application is virtually nonexistent. I’m not contracting in Iraq anymore. I’d spend at least $1,200-$1,400 on an upper that same money could be a Ruger precision or .224 valkyrie upper. In some ways the .458 would take the place of the .300 blackout I haven’t built yet, I rather have a suppressed .458 than a 12 Gauge. I guess I’m looking help deciding where to spend my money on my next project.

Again, .458 Socom ammunition cost comes up..... snicker. Store bought cartridges are expensive, but rolling your own using the 300 grain Hornady (#4500) or an identical bullet from Sierra keeps ammo cost down to about 50 cents per shot. That's very reasonable for a shoulder cannon!

The Hornady and Sierra bullets are designed for the 45-70 but they are the perfect diameter (.458") and weight (300 grain) for the .458. True, that deprives us of the versatility of the .458 Socom from subsonic heavy bullets to high velocity light weight slugs. I'm retired and need to keep the cost down!

A suggestion......
The .458 cartridge is a moose and it requires some "grunt" to size in the resizing die. Please be careful about what reloading press that you use. Some of the lightweight presses on the market won't stand up under resizing the .458 and they will wear YOU out!

I can vouch for the Dillon RL 550B and the RCBS Rock Chucker. The Dillon is a heavy frame aluminum press with steel handle. The Rock Chucker is a cast iron press with steel handle. Both presses are up to the task!

Lee die sets for the .458 Socom are very good! There are more expensive dies for that cartridge, but the Lee Dies work perfectly and good load data is found in the Lyman #50 manual!

I added the Lee Factory Crimp Die on 458 Socom for the last stage in the reloading process and in position #4 of the Dillon. It does a fine job and costs less than $20.

Yep. Lee dies and FCD are excellent.
