I would have given up at the start if I had to hand trim these. |

Does anyone have any data using unique powder?
I have a ton of this stuff and would like to know if I can use it in 300 blk also? |

if your shooting suppressed, try it on a few bullets, you'll be amazed on how quiet it is.
i often use that load for night time plinking as it won't wake the person in the next bedroom let alone next door. |

dryflash, what is the range of powder and COAL for loading 147/150gr FMJ over Lil'Gun with CCI #400 primers? Hodgdon jumps from 135gr to 208gr, and data from a google search doesn't give me a solid min/max to work with. Thanks.

(Wideners from 1998 when I had a M1A) I used RP cases and formed my brass, used Magtech 7 1/2 primers. Started with 14.5 grs Lil'Gun, worked up to 15.5 which was the max listed in my data. 15.5 grs had no pressure signs and was the most accurate in my work up series. My batch of bullets are 2 moa bullets. Good luck eta, my first post in this thread has the "how to determine OAL for bullets used in 300 blk". |

It's fairly well known that N110 is too fast to provide enough gas for cycling with the factory gas port location. That's why AAC suggests AA1680. I, however, think using 300 BLK for anything other than subs is laughable. so...funny you ask...I took a pair of wire cutters with me to the range last week. I was able to get one round to lock the bolt open in my testing (only 3 of the rounds were at that strength and 3 were 0.1 gr higher). At that point, the spring was so short it would not push the bolt all the way forward and I had to use the forward assist on every shot. That could be very dangerous and cause premature bolt opening, so DO NOT TRY THIS AT HOME. On the other hand, the spring was still plenty strong to strip rounds from the magazine (but I was only loading one at a time); it was just the rotation of the bolt into the lugs that needed the assist. I'm getting a couple differnet custom springs in the mail tomorrow and taking a pair of cutters with me to the range again. Once I get the bolt to hold open after each shot, I'll try functions with a full magazine (I hope I don't see custom mag springs in my near future  ). Worst case scenario: I'll have to use only part-filled mags.
Just be aware: You may experience feeding issues. Also, your rifle will no longer function properly with supersonics if you reduce the spring weight and don't add a gas adjustment (which is just a PITA switch around all the time, so I recommend just having a seperate upper for standard powders in supers and subs). My setup is for one specific load which is the only load I plan to use with the rifle at this time. Note: Some barrel makers design the gas port to cycle subs only if there is a supressor attached. Check with your barrel maker to find out if lack of a supressor could be effecting your results. Update: So, I tried the new spring today with no luck. It was just as bad as the original. I only tried on a full mag once, but the spring wasn't quite strong enough to get the ejector over the lip (my terminology probably stinks), but the round did chamber with minor forward assist [ETA: and maybe will chamber fine after the bolt is getting enough gas]. I'm pretty sure it was because I have no can and my gas port is set up to only cycle subs with a can; with a faster powder and subs with no can, it's just not going to work for me. I'll be scraping together some cash [but mostly credit] and a Form 4 in the near future...then I'll revisit this issue and try again. TTY in God knows how many months.

I looked a a couple others, but can't remember if they had any info listed. Had my hands full and was already getting close to my limit on what I was allowed to spend, so didn't take that close a look at them. |

Yes, but clean ALL sizing/forming lube from your brass. Running your brass through walnut or corn cob will only smear the lube off and then you just put the lube back on the brass. Brass + lube on hgh speed cutter is a sure way to ruin the cutter. You'll have better service life with carbide. I don't have a Girrd, but a CTS G2.5 power trimmer. Both index off of the shoulder.
Good luck.

So I am having somewhat of an issue. I have 1X fired LC cases which were formed to .300BLK and annealed by a member here on the forum. When I got the cases I ran them through my Hornady sizing die, then performed all case prep. The cases after being run through the die measure right at 1.360" +/- .002. Bullets used to load so far have been Sierra 110gr Varminter and Barnes 110gr Tac-X HPFB. (Not the tipped version.) In attempting to determine the proper seating depth I use the method illustrated by dryflash as well as load data from the various sites. I then check to see if the round will feed in my upper. So far my test rounds have fed and ejected just fine, but my problem lies in that in measuring after ejection the bullet appears to be somehow pulling out of the case. I would expect setback, but not coming out of the case. I decided to use the seating die to give the bullets a light crimp, and the crimped test round fed and ejected without the bullet moving.
So, questions: 1) Is my neck tension jacked up? 2) Will the taper crimp from the seating die be sufficient, or should I get the Lee FCD die? 3) What would be pulling the bullet out of the case since it is not hitting the lands? Thanks in advance. |

I want to share something that was shared with me by a man much smarter than I. The OP has a couple of choices , first I would like to provide some scenarios; 1. IF the pressure is slight on the case during cutting, the cutter "slides" over the brass, and this will dull it. 2. Depending upon the case lube, as all are an "EP" type, this will allow the cutter to "slide " over the brass, and dull it. 3. Depending upon how you "rough cut" the cases, IE; small abrasive/cut-off wheel, in combination w/ traces of case lube, this will create a "lapping" compound of sorts, and dull the cutter as well. 4. I advocate washing cases in HOT water and dish-soap, rinsing in HOT water, towel shake, 30 minutes in oven @ 200 deg.F AFTER re-sizing/rough cutting, or re-sizing period. Again, it depends upon if your case lube is water soluble, if not, you must use mineral spirits or lacquer thinner, or acetone. A little more info on this...case re-sizing lube is an "EP" (extreme pressure) lube. IF any traces are left on cases, bolt thrust becomes an issue, as well as the false indications of a "high pressure" load. (flattened primers etc.).Chambers/cases are designed to work together, as in the case expanding and gripping the chamber wall. Realize how easy a case will run through a die w/ lube and what happens w/ out, this is the "gription" that is supposed to occur during the ignition sequence. This, as well as Steel cased ammo plays hell w// the AR type platform, bolt lugs,(small and multiple), and barrel extension get beat to death due to this "non-gription" of cases to the chamber wall. As well, your chamber/barrel must be squeeky clean, you may realize all of the above, but I just thought I would share this info, w/ you, no dis-respect meant whatsoever. |

I don't want to go off topic with a lube discussion.
So lets end it with we disagree.

Thanks in advance. This question isn't really specific to 300BLK, but I'll humor you anyway. I think your neck tension is too loose as you suspected. (ETA: That's why semi-autos crimp; some need it some don't). My guess is the abrupt stop for the forward movement of the case when shoulder meets chamber [or whatever] acts like an inertial bullet puller. I'd just use whatever crimp you want and test it to see if it moves. |

Thanks, Noveau 1) I have used 300 Whisper data from Sierra 5 to work up loads for 300 blk. 2) Yes, what I'm doing with my 160 gr cast/2400 load. Thanks, Dryflash3! Noveau |

I'd recommend getting a Lee factory crimp die and putting a light crimp on your cases. With a little bit of crimp using it you can't push/pull the bullets out by hand, and they don't seem to go anywhere while chambering, either. Plus, it's cheap for a die, and that's nice, too. |

Will I have any length issues loading the tracers on the left? They are 146gr (M62). I'm thinking I should use 160-180gr data?
146gr Tracer, 165gr Sierra Gameking, 125gr Nosler

Anyone have trouble getting a confirmation email at 300BlkTalk at the ar15.com email? Been trying to register so I can order one of the case cutting jigs but the email never comes.
