New Remington 300 BLK UMC Subsonic ammunition.

[jessee]

I just got some being shipped now! cant wait!


OK UPS just knocked on my door and delivered them out of the first box all the brass is reformed 223 brass. Most with dings. Im not worried to shoot them but for $19 a box I expected new brass. Especially since I will be reloading it. Wont have my upper till next week!

I have access to Solidworks, but can't design with the program myself. I have to pay dudes to do that for me. I may have a magazine, 300blk case and proposed bullet shape modeled up to check for interference. Or, I'll spend $95 bucks and get a mold made. Design time isn't cheap, and the molds are at less than a hundred bucks. That won't even buy 2 hours of design.

An enterprising company with a vested interest in this cartridge (cough) could do all this and start selling 300 Blackout subsonic bullet molds if they were so inclined. Would save me a bunch of trouble!

That said, I've got very little in the way of casting experience. Would this shape even pour?



DESIGN - BORE RIDING SECANT
AS CAST DIAMETER - .308"
CAST WEIGHT - 220GR +/- 2.5
BULLET LENGTH - 1.573"
MEPLAT % OF DIAMETER - 10%
LENGTH INSIDE CASE - 0.583"
REQ. TWIST - 1:7"

I know some of these dims are not right for the application, was just looking for a general shape.

I am curious to see your worst dent.

The ammo in the original post has been showing up in Walmarts in Late November thru December 2013. 4 to 8 boxes per store in Alabama and Central Time Zone Florida

I got FTF with 25 rds....brand new upper... I wish I had a differnt ammo test. I dont belive it my upper or my clip. I will be doing some research on here and the rest of the web.

Fires round, ejects casing, will not chamber next round

[300Blk]

Need buffer weight, gas system type, gas port size, type of spring, type of silencer, type of magazine, etc.

OK, apparently this can be done! NOE mold.

I got a couple of boxes of this new ammo locally today. There are some small dents and dings on the brass, but they should shoot just fine.

Pouring is not the problem. The ogive will likely bend when it hits the feed ramp.

This is what I would think.

From my last order from midway - Out of a box of 20 and the 6 boxes I have gone through, 80% of rounds in the box look like that
