Who's got a semi and what kind..... I'd love to pick up an accuracy international as-50 ....id trade my aw-50 for one
50 bmg ammo
- Thread starter Brian46
- Start date
it's cycling LC M33 ball. No stoppages, fully cycles the action.
thin, stretching, lots of trimming. loose primer pockets, Just a lot more work overall than LC and I chucked it after 2 reloads
The X is a reject, google is your friend as this is common knowledge, and again, when this ammo first came out pics of the loaded rounds with holes/cracks in the cases were posted. On a bolt gun these are all hard to extract when compared to regular M33 or IVI Match, each round is out of spec in some way or another or it would not have been rejected.
Quickly looked for the thread with holes and didn't find it, but this shows the type of common problems you will see with the XM33 being out of spec rejects

Post #52 is the retailer selling the ammo confirming the split cases

I do not believe the AS 50 is available to us.
You should test the velocity, and report back.
I did made a mistake though, this XM33 ammo average was 2640 fps with the stuff I did test. Since it's actually Lake City ammo anyways that probably means the PMC ammo is hotter then the LC M33 ball, go figure...

you can't compare xm33 to M33. It does not say on the box of the XM33 why it did not meet military stds, it could very well be that it would not cycle the action on the M2 along with the poor quality brass.
I even have some LC M33 from 1944/1945, current production is way hotter
What gun are you running the XM33 in? Do you not find opening the bolt more difficult (hard extraction)?

I'd love it if you could get components, ie. once fired brass and projectiles, new or pulled
Nice, If the price is good, I am in for a lot
There is a lot of people using that ammo with no problems, and to call them all rejects and out if spec is saying a lot.
You need to crony some of this ammo to get a better idea what the factory stuff is doing. The main reason I bought factory ammo was to test it so I could mimic it with my hand loads. I would love try some of that link M33 for comparison but I can't see myself picking up a case with our current dollar being so low.
The rifle I used was a serbu BFG-50A with a 26" barrel, no problems with operation.
That is what the "X" designation means in front of the std M33 designation for the ammo.

Probably cause "i" was over done lol!
Look, it's surplus ammo anyways, as long as it goes bang and hits minute of tank that's good enough for me

Rejected by the US forces strict and stringent standards is a key thing to remember. The ammo the US forces picks literally has lives depending on it. I've shot a decent amount of the LC 7.62x51 and it's good ammo, went bang every time and groups half decent if I do my part. That being said I have noticed the odd round will have a slight dent or imperfection in the brass but haven't seen a crack or puncture yet. Also about 20% - 30% of the brass is dirty some worse than others, cleans up but dirty nonetheless. It's great for our everyday use really. If you pick through it after it's fired you will still have some great reload able brass in the pile.
You can dismiss everything I posted, I don't really care. The link I provided to pics of the problems with the ammo and the dealer asking people to check for and send back cracked and ruptured cases for exchange speaks for itself.Probably cause "i" was over done lol!

I also wont shoot it out of a bolt gun unless it chambers easily.

I've put quite a bit of PMC Bronze through an HS 50 I used to own and through an LRT-3 I currently own.
Lets be realistic about what ones expectations should be with this ammunition; its purely for economical enjoyment of your .50BMG. Plinking ammo if you will.
Underpowered? Compared to what? Any .50BMG ammunition shot from less than a 32" barrel is going to be "underpowered". Who gives a $hit if it's 100fps slower than M33 or whatever (if this is even true). Dial in some extra elevation and enjoy. After all were talking about 2moa ammo here. Not match quality.
As for the brass, if you are experiencing case stretch, excessive trimming and loose primer pockets resulting in discarding the cases after 2-loadings I would blame poor set-up of your sizing die and excessive pressure more than the brass itself.
Its certainly not IVI Match but its serviceable and cheaper to buy as loaded ammunition than new IVI Match brass itself costs.
I've loaded PMC brass for my Steyr and had 1moa capable plinking ammo with weight sorted and sized 650gr pulls.
My 2-cents FWIW.

I would agree that it is not the brass if I was seeing the same issues with all my brass, not just one type
once fired IVI Match brass is not overly expensive if you can find it.
The steyr is quite accurate once the brass is formed to the CIP chamber.

You're right, I managed to gather a quantity of IVI Match for a very fair price. As for the Steyr it was a very impressive rifle.
It was capable of fine accuracy and though I never chrono'd my loads it was noticeably faster with both 650 and 750gr bullets than my LRT-3 is. The LRT-3 shows intolerance of pressure far earlier than did the Steyr.
