NOE sells another popular one that is more expensive.

I have used both.  I prefer the NOE mold, but the lee mold worked also till I ruined it by trying to make it into a hollow point mold.

I'd like to see some math behind this claim. Often, people forget to consider the value of their time as part of the expense. If you're saving $10 per hour, but your employer pays you $12, you're actually losing $2 by casting your own instead of just buying them and spending an extra hour at work.

...not to mention the health hazards associated with handling of lead on a regular basis.

I have never really cared about saving money on reloading and casting.  for me it is part of the hobby and enjoyment of shooting.  I take basic precautions, but frankly nowadays everything will kill you, so I don't lose sleep over it.

I'm not able to measure any mags at the moment and thought someone might have this bit of info.

I don't "skip" work to reload. . I do it in my free time.  I do it to learn something new, to dive deeper into my firearms capabilities, and to give myself more flexibility in load creation.  

If I end up saving money doing it myself as well, then great.  But saying your own time counts against the cost doesn't make any sense, I don't pay myself a salary.  The whole point behind doing something (anything) yourself is to actually save yourself money, not to spend more.  That's why I spent $25 in parts, and several hours in time to fix my dryer myself.



Not to mention, I am salaried.

It's just a factor to consider. If you enjoy doing it, that's great. Me too. If you're doing it purely to save money, you may want to go ahead and actually calculate things. Your "free time" is essentially time you can do anything, including work for pay; so I still hold to my original statement.

Due to the increased price of ammo and advent of the 300 BLK as a SAAMI round, reloading has become a fad. Now more people will likely get hurt by their own guns. Thanks Obama.

Maybe someone can help me figure this out. I decided to play with my 125gn Accubond load to refine it a bit.

I shot these groups today in 5 - 10mph wind that was swirling. The groups were at 100yds., so the wind shouldn't have this big of an effect on bullet flight, and the charges were thrown from the Charge Master. So, the charge couldn't be off this bad.

My problem is I can't figure out how these two flyers happened. These are both 5 shot groups with 125gn Nosler Accubonds out of a 16" barrel. Yes, that's 4 shots in one hole with Lil'Gun. If it weren't for the flyer, it would've been 5 shots in one hole.

Is it the Lil'Gun doing this, or the Accubonds? I've read somewhere that other folks have had these problems with 125gn Accubonds out of the .300blk. Does this hold weight? You think it could be the R 71/2's?

I don't think we can ever rule out shooter error. Unless the weapon is locked down. In this case, I was using a front bag only. The method of calling your shots on a separate target is a good one, dryflash.

That's something I didn't think about using here. I'll give that a shot tomorrow just to verify it's not me, and use a rear bag. I'll also put 10 rounds down range instead of 5.

I think the wind is supposed to be better tomorrow also. Thanks, fellas.

It was cold so I went to the indoor range with my 300 Blk. USA tactical firearms lower, Wilson combat trigger, 16 in. CMMG upper,
Vortex Strikeforce optics Yankee Hill Machine 30 titanium suppressor and shot this 25 shot group at 75 ft offhand.


the 4 shots to the left
220 Sierra HPBT 10.2 lil gun , short stroke on all rounds
4 shots to the right,
220 Sierra HPBT 9.9 296 no malfunctions
big raggedy hole
125 Nosler BT 17.5 IMR 4227 no malfunctions
150 Sierra FMJ BT 14.0 IMR 4227 no malfunctions
220 Sierra HPBT 10.5 IMR 4227 no malfunctions
220 Remington factory load no malfunctions
Seems to like IMR 4227, Wilson combat trigger expensive but rocks, Strikeforce optics are clear and the dot is sharp
no appreciable shift in POI between red/green dot, YHM suppressor sound like an air rifle subsonic, and maybe a 22 mag supersonic

After each shot I look through the spotting scope and note where the shot went with a number on the dupe target on the bench.

You should know where the cross hairs were when the shot broke, that is how you differentiate if flyer is the load or the shooter.

Good luck

I figured my problem out. Neck tension! I anneal all my cases before I form them. But I don't anneal again until the third loading. So I skip a load then anneal. Which I think at this point is going to change to annealing ever loading.

As for the OP;

110gn Nosler Varmageddon (34057)
CCI41
20gn H110
2.050" COAL trim length 1.360"
Light crimp .002"

This load puts 10 shots inside a 1" circle at 100yds. As for velocity, I don't know. My chrono doesn't like SUN at all. But to guess, and according to Quick load, it should be around 2400fps. out of a 16" 1x8.

Wonder if that could be the problem I had with my last outing using the Tac-TSX bullets.  I'd have a few that would be within 1/4" at 50 yards and then one flyer that would be 2" or more in a random direction.  I've got a lot of brass with several loadings, but still no cracks or anything in them, and they get trimmed down after every firing/deprime/resize cycle..  But, they haven't been annealed since I first made them.  I did a noob reloaders dumb thing and got my shot/resized brass mixed in my newly formed brass, so I might grab one with 0-1 loadings out of the bag, or one that has 4 or 5.  That would probably explain the random flyers in an otherwise good group.  I am doing a crimp with a Lee FCD, and I'd have thought that would help, but maybe not as much as good annealing will do to the neck tension...

The Lee FCD is how I figured out it was neck tension. Then I annealed 50 pieces, and shot them. They shot great; like match ammo! I was so pissed at myself.

My shots, as you can see from above, were all over the place. Nothing I did was helping.

Maybe it's just too early for me to understand, but how did the fcd help you figure out it was neck tension that was the cause of your accuracy problem?

I put some rounds together with a very light crimp to see if it helped accuracy. When I shot the same load, my group significantly tightened up. I have NEVER had a FCD work for accuracy like that. So I went ahead, and annealed some cases, loaded them, and shot them. Accuracy was great!

The FCD put an even neck tension on the finished rounds, and that's how I figured it out.

ETA: I'm starting to think for converted cases, annealing them for the first 3-4 loadings is paramount for neck tension. I don't know what neck tension is supposed to be for the 300blk., and I can't seemed to find it anywhere.

I've used the fcd on everything I've loaded so far, and I still get flyers. I have had a few bullets, though, that I was able to very easily seat with the press, while all others took a bit more force. Maybe I need to lock the fcd down a little tighter to impart a bit more crimp? (Besides annealing, that is). I have another 200 or so brass I need to convert sometime soon, so I might just dump all my old brass that has between 1 and 5 or 6 loadings on it and start fresh. That would eliminate the question of how many loadings the case has that I pull out of the bag.

Are you measuring the crimp, or just putting a crimp on, and rocking on? I measure everything, and may be a little OCD with it. I only use a crimp when it's for plinking ammo, or when all else fails.

Not measuring the crimp. Just putting enough on it to keep the bullet from moving around when it's chambering. At this point I'm not loading anything for the 300 except tac-tsx and ttsx bullets, btw. I need to make some more lead subs for plinking, but it's going to be a while given the weather. Would love to get some 147 or 150 grain fmj bullets, but I don't want to spend 250 at a time getting them.

Mr Nasty, please perfect these. The BLK community is in need! At least I am. My new Leonidas needs some frag-nasty subs!

Just loaded my first .300 AAC rounds...

I'm going to see how they do... please speak up if something doesn't sound right.

15.0gr of Accurate 4100, COAL of 2.060
15.5gr of Accurate 4100, COAL of 2.060
16.0gr of Accurate 4100, COAL of 2.065
16.5gr of Accurate 4100, COAL of 2.065
17.0gr of Accurate 4100, COAL of 2.065
17.5gr of Accurate 4100, COAL of 2.065
18.0gr of Accurate 4100, COAL of 2.070

Based it off of this...

Did I go too short (dangerously) on the COAL?  Do these sound like safe loads?  It's been about 3 years since I've done any reloading so I would appreciate a second look from anyone who's experienced with this cartridge.

I use this trimmer for .223 and 330blk. It works very well and is very consistent for me so far. It is kind of a pain in the ass to set the length you want but once set it is GTG.

I put small pieces of blue painters tape over the holes in it to keep the brass from flinging all over the place. Just pull a piece of tape off one side and dump it out every 50 or 60 cases. Trimming as much brass off as the guy in the vid is removing it will need dumped out more often.

Thanks for the reply . I figure after the chop saw method I would use this trimmer finish length trimming after sizing. I have a old tumbler body that I might put between the drill chuck and body to catch the brass. An old router table may work with the drill mounted under neath ? The WTF will be here wednesday.

You're right. So I retract my statement. But still want to know what bullet?

I thought COAL was subject to magazine bump in the end.

Um, that's one way of putting it. LOL

Considering I already reload I ended up doing some lengthy research into swaging and whether it would be worth it for me, sourcing the materials needed etc. Easily into the thousands from what I read over a few hours. Corbin has a metric ton of information.
