.50bmg

It says out of stock! I just ordered direct!

Another go to load is 215 gr H-50 under 750 gr AMAX not the best for velocity though but have shot sub 1/2" at 800m. allot of North American standard .50BMG accurate chambers this load is med you can work up to another accuracy node with more velocity. If you are not very experienced start around 205 grs and work up. Some of the CIP chambers could cause issues depending how much free ore they run.
 
I had the Grizzly it was a nice unit! I bought a Bench Source and really like it best, Annealer I have come across. It cost me close to $600 with the .50 carrier plate as well.

Have you experienced case denting? Keep a close eye some are small but sharp could cause case failure. If you see dents just add some tubing to your charge handle or piece of MTB/MX grip.



So far no, just looked at a box of PCM brass and they all looked fine but I'll keep that in mind.
 
The surplus pulled bullets can shoot sub MOA if you sort the ogives with a Sinclair Ogive comparator. I also size them through a lee sizer just to take down some of the pull marks. Swissin shot MOA at 700m with my loads of US-869 233.7 gr even more accurate I use H-50 BMG powder 237.5 gr seated to canalure groove with med crimp. Anneal every firing and after 4-6 reloads you will probably need to ream the neck out to remove donut at the neck shoulder junction. You can make your own bump die out of a lee FL die if you know someone with an EDM machine or special tooling.


Hi,

Do you have some pictures of the process before resizing the bullet and after using the Lee Bullet Resizer.
I am going to buy that sizer. Very good idea.
 
Well the Lee sizer works ok to remove pull marks by knocking the copper down on AP core rounds. The CH4D might be a better option as it sizes .5095" or custom order spec.

I will get some pics next time! Not much to see the AP core rounds remain more concentric then say mild steel or lead core pulls that's where the Lee sizer might be even more beneficial or better yet the CH4D .5095" sizer.

OK
But a little bit more expensive

There is a 7 weeks delay for the sizer for CH4D

do you have another supplier ?
 
Alot of good advice and info here once you get past the origional zombies remarks, lol.

What i find funny in these posts is the mention of "Cost".....guys..... they're 50 bmg's...lol . What did you expect? Buying them is the easy part, its feeding the pigs and the cost of load developement that hurts.
We need more pics here and peoples loading notes to help others save time and money.

I've not loaded with US869 myself but a friend has and likes it. I've used the H50BMG and I found it dirty, expensive and had a sharper recoil.(there is enough already with a 50)
I used a fair bit of H5010 and liked it.
The 50 I had is long gone now but I still have some of the materials I was loading with and would consider buying another one day.
For brass cleaning I've never done the water wash routine but did use alot of brass from surplus ammo i'd fired off.
After returning from a machine gun shoot in Kentucky i'd bought a solution you dilute with water and soak the brass in. This tends to colour them so after that i'd tumble them in corn cob media. Afterwards inspect them and remove any offending media.
Then use a primer pocket reamer to clear up the ugly factory pocked, then with a small wire brush (round) in a cordless polish the inside of the next and used ultra fine steel wool to polish the outsides. Obviously and brass with the double primer hole were given away as gifts to people for key chains etc,

I don't have my loading notes handy from what worked for me but I remember while a buddy was using heavy loads like posted before I was using much lighter ones and getting very nice groups at 100 and predictable accuracy at 1000.



This pic is decieving. only 6 rounds are in the center hole, 2 flyers are from me flinching when a black power rifle next to me went off as i was about to shoot.

Very nice post.

A lot of good down to earth info.

For Powder, I use the US and the H50 but yes they kik and are very dirty,

You want very clean powder go VIT. But do they are expansive.


NO NO NO I will not say Zombie. I have been clean for 5 weeks. ok
 
Help from any ax 50 bmg owners

So im running an ax50 bmg with a s and b pII with a h37 retical, in acuracy international 45 moa rings. When I zeroed it at 500 yards the other day with xm33 ammo it took 11 mills of elevation to get on target, so now I only have 16 mill of elevation left in the turrretd. This seams a little excessive to get to 500 yards. I know on my 300 win it only takes 2.5 mils of elevation to get to 500 from 100.

Is there something wrong with this setup or is this ammo that bad? I havent had time to do any reloads for this gun and I did not want to touch my hornady ammo, seeing how I cant find any of it right now!

Indeed it is a lot. I have almost the same set up an AX-50 with an AI scope mount and a Hensoldt scope.

The XM-33 ammo is not my first choice for over 500 y shooting. It is a 630 gr bullet with a military load. Targets are a little closer for the M2 machine gun.

Please recheck completely the set-up, torque on the screw should follow military standard so the upper limit for torquing. If possible upload a picture of the set-up.

Whats the point of a 500m "0"??? I zero all my precision rifles at 100m including the .50.

Consider this: with a 100m "0" and 26mils of "come up" you can get out to just under 2000m with the Federal XM33 ammo. How much more do you need?

I think the fact you are trying to zero the gun at 500 is eating up your elevation. I bet if you zero at 100 or 200m you will restore the full range of your elevation adjustment.
 
That does seem like a lot, in my ballistic program the xm33 is showing a drop of 2.48 from 100 to 500 yards. If that's a one piece mount you sure you have it turned the right way?
