I have some 458 hardened lead bullets I use for 45-70 that have a brinell hardness of 18, will this still cause issues with clogging the gas port?

Edit: Suppressed too

Found a guide and bent the tube for clearance and it's closer but still not perfect. Pic is before bending and tube isn't in all the way so you can see it hitting the top of the gas tube channel. I found there is a gas tube alignment tool for $40 and I am going to order it and stop effing with this for now.

The 458 carrier and bolt I use between guns and the gas key is tight. The Tube is wonky, but alignment is perfect. Weirdly enough the other 2 carriers I tried slide right on this tube. Only the carrier I use with my 458s has this issue on this tube.

I'm not sure if anyone else has encountered an oddball scenario like this but the tube is definitely misshaped.

This is the best my cellphonetography skills could do.

Hoping the new tube solves this issue.

There's a 9.75" rando brando that would match the Midwest but the 9.5x Geissele was a good deal. The Aero P-Nut butter in 10" was just a smidge too long.

Need to go a size down on rail. No biggie just a swap.

Got my barrel and hadn't decided on the block yet and will be running sub and super as with my 16" Tromix upper. If I go adjustable, it'll be the superlative arms since that's what Tromix recommends.

But just wanted thoughts, I have my charging handle sealed and it's not too gassy on supers suppressed on my 16"

Looking into getting a 458 and have thoroughly enjoyed every Wilson I've shot. Can anyone elaborate on their tactical/Hunter 458s?

Anyways looking for a cheap lpvo or red dot for my 16in. Will I be happy enough with vortex? I have a bad astigmatism

Did I miss something? I thought standard uppers would work?

I’m looking to stay subsonic in a 16” barrel. .458 socom loaded with hodgdon lil gun behind a .458 sized lubed hardcast Lee .459-500-3r bullet. I found Lyman’s data recommending 19gr for a copper jacketed bullet but I know cast is going to come out faster and it’ll need to be reduced to remain subsonic. But, how much to reduce it? I’ll be loading them for a friend who lives across the country, so the fewer back and forth testing the better. I’m sure someone on here’s done this. This is also a friend with his SOT so of course it’s suppressed and full auto. Should be a guaranteed good time if we can get these subs to cycle reliably.

For the life of me I can't find one, I found so many old threads referencing anything below 10.5" being available in fast twist, but no dice on finding one.

Edit. What's the going max weight for a 10.5 1:14 before I start to see issues with needing the 1:10?

Anybody else had trouble with the 16.25” lightweight Tromix barrel not stabilizing the black butterfly 576gr subs?

I know lancer is the typical answer for what magazines work best for .458 socom. But I'm wondering if anyone has attempted to sand/dremel the divider in the Gen3 PMags before

Is there a preferred reloading die for 458 Socom? Or just use what brand you normally do for other stuff?

Need some advice on a buffer to use on a 16inch

What bullet and powder combinations are you using that work well? By well I mean 1 MOA or better?

I'm having a heck of a time with Hornady 325gr FTX. I've tried IMR 4198, IMR 4227, and Accurate 2200. So far the best is with 4198 but, shooting past 100yds, the groups have been going to crap.

It's a Tromix barrel, Bowers Dreadnought, Trijicon Scope. All things are fine, in spec, torqued correctly etc etc.

So I just got a Gibbz G4 upper and wanted to replace the factory upper on my Tromix 10.5". To preface I've never removed or installed a barrel before, but I'm going off the barrel change guide that came with my Avid armorers torque wrench set. The guide instructions look pretty straight forward but I wanted to check with the community on recommendations for what grease to use on the barrel threads and what is the recommended pounds of torque I should be using for a Tromix barrel? Any advice or suggestions for my first time doing this would be greatly appreciated

Looking for a solid light that can withstand 458 recoil. I’ve tried multiple streamlights and they shit the bed on me almost immediately.

This could be rhetorical bc I know surefire will most likely hold up, but if you guys are using anything that works and have a recommendation that would be even better.

Note: Going on a 10.5 suppressed SBR

Ready to make an complete upper, just got a great deal on a bare upper only, will be doing an SBR lower since I don't think my Maxim will take the recoil in that short buffer system on the pistol.

I'm not married to using Tromix and already have a 16" 458 with a Tromix barrel.

Thanks

Just ordered my complete upper with 16"barrel for 550$. Not bad at all considering when i built out my upper custom on the website it came out to 1050$. Hopefully this will help some of you get that top tier upper for a better price

First of all, thank god I came away with only minor scapes and bruises. But can we talk about how bad Bear Creek’s .458 BCGs are? Gun was on safe, I chambered a round (since it was brand new and I like to make sure that the upper feeds properly, so I load a couple rounds in the magazine to see if it feeds properly) long story short, firing pin struck the primer as I was trying to send the bolt forward using the forward assist and sent the round into the carpet (in a new house btw). AGAIN THE GUN WAS ON SAFE AND STILL TRIGGERED A ROUND TO GO OFF.

I got one of the lancer 10 round (5.56) magazines because I was told it could hold 5 rounds of .458 however I was only able to fit 4 rounds in. I just swapped the follower with one of the center feed followers from Tromix but now it can only fit 3 rounds in. I'm wondering if anyone else had issues using lancers 10 round mags or maybe I just installed the follower backwards.

Got it all together and it ran 20 rounds flawlessly with lancer mags (I also have Tromix followers but never tested without them)

This is what I’ve got.
