Any thoughts on using 147gr FMJ loaded to 2000fps as an SD load in a pinch? That's mostly what I've been loading lately.

My 150 grain FMJ loads were around 1800-2000 fps. They were pretty comfortable to shoot, too. I don't know what kind of results you'd get in flesh with this kind of bullet though, so I'm not sure it's a good choice for a defensive load.

I am going to offer a bit of a PSA here on .300 black.
I have been doing them over a year now and I have cut them with the tubing cutter(slow and a real pain in the ass), I built a jig out of a piece of wood to hold 10 .223 shells and cut them off with a dremel and a blade, another pain in the ass, about three weeks ago, I purchase over 1400 shells with a jig and the HF small saw with the .300 jig and have process all 1400 of those shells. Moral is, if you are going to make your own .300 shells, then save yourself the money, buy the saw, purchase the jig and get on with business, the saw with the jig makes it so much easier, and faster, you will wonder why you didn't do it. PSA over! |

Yeah my thoughts as well, was thinking it would still sting a bit and be on par with a x39 ball load, though. Or a .308 at around 350m. My SD loads in .300 are 110 Vmax and 125 TMK mostly but since I've got 500 147gr loaded up and set back was wondering about them as well. One day I'll get into gel testing and post it all up on Arfcom. I just got a chrono so now I can collect and post that data too. |

I'm still trying to pick a mold for casting subsonic bullets. I was going to go with the NOE 311-230 FN PB but they're OOS so now I'm thinking about the 247gr. Has anyone here tried that particular bullet?

Has anyone here tried that particular bullet? I have had good success with this bullet but it required using the 300 blackout D&H magazine from BCM that has the rib set back to accommodate the wider bullet. Also, I widened the feed ramp to allow the bullet to feed without shaving any lead. These were plain lubed boolits. The one on the left is the 247, the middle is the same but in HP. The right is a Fat McNasty (no longer being made).

For now, I've stopped shooting cast subs in the AR. Running jacketed until a better mold comes around. There is one on the horizon designed to be powdercoated. |

Use the .250 ogive method to find OAL.

It will give you functional OALs - but don't be surprised when they are nothing like what the manual gives for an OAL for that particular bullet. On a related note, there are magazines made specifically for 300 Blackout. They are adapted for the larger diameter bullet and shorter case by having the rib at the front of the mag at a different location. To me, this is an OK thing, but it's also a potential problem. You have to look hard to see the difference between the rib locations on the standard magazine and the Blackout magazine. A little experimenting with an ASC 5.45mm magazine was an eye-opener for me - feeding 5.56mm dummies from that magazine was so crappy that it was comedic. I'm sticking with the .250 ogive method myself. |

Just found out Hodgdon reworked the supersonic data for Lil'gun...... 2,474fps 110vmax 2,402fps 125 Nosler BT 
Data posted on Hodgdonreloading.com. I was told there was a reason they held Lil'gun to lower pressures by Robert Silvers on the 300blktalk forums a couple years ago. He refused to specify what the reason was. Heard speculation that the powder had unstable pressure curves at heavier charges, but If these numbers pan out this is a rather large step up in power for this round. Thats about 150 or 200 fps faster than anything I have ever seen with a 125. |

I'm having feeding issues with my new 198gr NOE bullets due to the rounds being pushed together by the ribs in the magazine (Lancer AWM and D&H with Magpul followers). I'm thinking about giving the .250 ogive method a try but I'm concerned about ending up with a compressed charge.
With the bullet seated per the ogive method the OAL is 2.05". Using 10.5 grains of RL-7 the powder is very lightly compressed. 10 grains and the bullet is just touching the powder. 9.5 grains gives ~.060" space between the powder and bullet. 9 grains gives ~.075" space between the powder and bullet. I haven't tried any of the above loads yet because I wanted to make sure I'm not going run in to overpressure issues. My current load has an OAL of 2.14" and with 10.5 grains of RL-7 gives me right around 1,000 FPS out of an 8" barrel. Will I be safe trying any of the above loads with that short of an OAL? |

Adjust the OAL with your bullet seating die until the .250" mark on the bullet sits at the center of the front magazine rib on a 5.56 mag. Your die is now set for what should be the correct OAL for that bullet. The neck on a loaded 223 is roughly .250" diameter. The front rib on the mag is designed to guide the neck. Thus if you set the bullet depth so its at the same diameter at that point on the mag it can do its job as intended - keeping the rounds aligned in the mag. You should experience good feeding without downloading mags. If that front rib pushes on the bullet you end up with rounds stacking wonky in the mag. Here I scribed a 250 line with calipers and my oal is slightly long  Attached File |

The .250 ogive method is on page 1 of this thread. Also above.
I works with 180 gr and lighter bullets. You will have to shave down/file the front rib. Normally done on a Magpul or other plastic mag. Once you do this, mag will not work with 223 rounds. So mark mag well to avoid confusion. |

I also shaved down the ribs a bit on my Lancer smoke mag which I had already designated for 300blk use only. With 10.5 grains of RL-7 I'm averaging 1040 FPS with no feeding, chambering or cycling issues. |

Actually 18.0 grains and 18.3 (5 rds each) were pretty close in accuracy. I loaded up 10 rounds each of 18.0 and 18.2 and 18.2 had the nod toward a smaller group. This was with Rem factory primed new brass (that I've had for a few years in vacuum sealed bags). Using the method alluded to in a couple of the following posts, I came up with a 1.665" OAL. This load even shoots close to my Speer 125TNT bullets, so I won't have to worry about resighting regardless of the bullet. I'm using a Noveske 8.2' bbl with a 1:8 twist. Have fun! |

I'm using 10 grains of RL-7 and seating to just shy of the ogive method for ~1000fps. ETA: The red flakes in the lower are pieces of powder coat. So far I'm not seeing any build up of any kind in my barrel or suppressor.  Attached File |

what is the bullet diameter and how thick is the car at the neck? Compair that to start is the od of the neck of the assembled round. Are you sizing the budget when you seat it? If you aren't then that might not be your issue.
Eta: on rifle dies I always suggest redding. Engender that the die and bushings are sold separate. I have been using just the redding comp die set with the carbide expander though |
