What did you do in the reloading room recently?

No reloading for 2.5 years due to moving house and having kids. On the plus side my 1 year old is super interested in the “tools” - knows how to swage 5.56 primer pockets, and knows you need a grease gun to lubricate a dillon 650.
Was wondering what happened to ya lol. Hadn’t see your posts in a bit.

First time I heard someone telling me about that, I thought they were pulling my leg. As I recall they were talking about working up a 22-250 with something like 40 grain varmint bullets and they couldn't figure out why they weren't even on paper at 100 yards. Somehow they eventually pieced together that the bullets were coming apart somewhere between the muzzle and the target.

Are you speaking figuratively, or could you actually see the bullet disintegrate? I can't even see the shot string on a skeet range, so I envy those with eyesight that allows them to see vapor trails and stuff like that, that I can only see on video.
If you find that your bullets are tearing them selves apart you can see it sometimes as an by stander if its happening at close range
I have 2 personal experiences so far
1. 50 grain varmint bullet through. 1/7 223 AR pushing 3000fps the twist is. Just to fast.
2. Went through the same issue with some early Hornady 30 cal ballistic tip bullets. Those I did not see but eventually started getting random shards on target at 50 yards when I was trying to figure out whats going on.
Hornady put out a video on it …I cant find it at the moment.

Sweet. 4000 ft/s 22-250 birdshot!!!!

The 22-250 was designed around fast light bullets and had a slow 1-14 twist so you could push 40-55 grain bullets well past 3000fps a 60 grain bullet out of a 22-250 was “heavy” for its time. The old timers would tell you its to heavy and time to up your caliper.
Its all a balance between bullet design, jacket thickness for jacketed , velocity and RPM.
This is why if your shooting cast out of something like a 1903a3 or a M1a or even A AR your limitted to around 120-140,000 rpm
Vs say a old rifle designed before jacketed bullets will have a much slower twist

Like the case gauge loading blocks 👍

I load a LOT of 9mm, and I chamber check, (or case guage), every round. I have 7 hole blocks from EGW for 9mm, .38spcl and .357sig. The 100 hole blocks aren't cheap, but it's just so much easier to check 100 at a time. 45 is new to me, just started loading it, so I don't have a 7 hole block for it, just bit the bullet and bought the 100 round one.

I have those shockbottle hundos in 4 calibers. If you consider the cost of them to be about $1 per hole, they are actually much more affordable than the EGW or Dillon case gauges.

Great. Just fcking great.
Now I'm thinking about getting them in .38 & 357Sig.
Thank you so very much.

I was getting ready to load some mixed headstamp 9mm, and ran a magnet through the brass before loading. This case came out. Does anyone know this headstamp? The case is brass in color, even though the lighting of the picture doesn't appear that way.

Seems to like this one:
View attachment 547052

I'm calling this load development finished. As I went up in powder load from here, the groups started opening up. May have been me getting tired and my form going bad, but... this seems pretty good, considering. Brass looked fine here, no ejector swipes or extractor scrapes, no abnormal pressure signs on primer.

24.7 grains of IMR 3031
50 grain Z Max seated to 2.260" OAL
CCI #41 primer
Lake City 2009 brass trimmed to 1.760", shoulder bumped back 0.004"
3027fps five shot average, 22fps SD
16" Colt 5.56 1/7 carbine barrel, standard handguards and front sight gas block
4x fixed power optic
100 yards

Your probably pushing those 50s to their RPM threshold with thst 1/7
I have some 50 grain noslers tipped that wont do well much past 2800 fps with any powder out of 1/7 match barrel

I hadn't tried calculating that before, but I'm coming up with 311,348rpm average.
Fastest chrono from that test series was a 3058fps at 24.9 grains, so that comes out to 314,537rpm, I think.
I guess I could try to see how fast they can go before they go poof, but I'm at the upper limit of the load data for .223. :)

I played around with .223 vs 5.56 load data with AA2230 and 55g fmj bullets, but I didn't see any particular area where they really grouped well, and as I crept up on max 5.56 load data I was getting fairly pronounced ejector swipes on the brass, with a lot of brass shavings under the extractor when I went to clean the bolt. Same as I get with real Lake City m193 in this one.

It’s been a while since posted around here but been staying busy reloading mostly for the precision rifle stuff. Mostly 223 and 6.5 creed. Just finished a 6BRA build so loaded up 25 to test for fireforming.

Lapua Brass
IMR 4064
Br4
Hornady 105 HPBT

If these run around 2750-2800 I’ll proceed. Got 300 pieces of brass to form.

Looked for my special Swedish 5mm Training ammo barrel for my Uzi…..DAMN IT!!!! I put it an ammo can diagonally along with loose training ammo a couple of years ago and evidently didn’t label or mis labeled the can. Now I get to open every can in the building……that’s going to take a few days. ( insert head bang emoji here ).
