Not sure of its origin... but it does seem to be 50-70fps faster than the A1680 was with the exact same load. All ive read online says its basically the same.
12.0gr of the A1680 was only going 980ish fps.
I will need to test for accuracy next.

Anyone tried the 217gr Hi-Tek coated Gallant bullets? I just got a bag of 500. Using CFEBLK/CCI400. Loaded up a mag at 12.0gr, 2.25COAL to test out. Learned the hard way that my mixed plinking brass trim lengths are not consistent enough for the flaring die. Even though they have a boat tail they still require a good amount of flare to pull out cleanly.

Anyone have any load data for Speer Grand Slam 150 gr SP and H110?

Closest I can find on Hogdon.com has 14.6 grains to start out and max of 17.2.

I split the difference and went with 15.5 grains.

Go to speer-ammo.com and go through the menu picks. I found the Grand Slam in the second set. Look at the bottom for Win296.

That said, I’d recommend Lil’Gun for that weight.

ETA: Don’t select powder type.

Thank you sir!

First round of reloading of any type. This is more proof of concept for me as opposed to searching for perfection (at least at this point).I’ll grab some lil’Gun for alternate projects later on.

Appreciate it.

Actually looks like I might be a little underpowered at my current charge.

Any good subsonic loads for 150gr bullets?

Will be for a suppressed 8.5” and needs to cycle and have bolt held open in last round

Just trying to keep reloading costs as cheap as possible since it’ll mainly be a plinker

Berry’s looks interesting

Will it leave a lot of residue in your barrel/rifle being copper plated?

Also, what’s a good recommended powder and how much powder for a good subsonic round for a plinker?

Anyone pushing 110 gr VMAX with H110 through a 12.5” AAC branded upper?

I’ve loaded some rounds up from min to max charge and now I just need to take them to the range.

Seems like this would be a good “thin skinned” game load.

Yes with Win296 (been told it's the same powder) through my 8.5" 1:7 PSA.
Plinked with some 18.8gr/CCI400/2.05in COAL @ ~2,090fps. They feed/function great. I have a ladder loaded up that I haven't grouped yet. They do seem to require some flare to prevent shaving brass due to the flat base.

The benefit I'm seeing is that they seem to have the same POA/POI as my 110gr TAC-TX hunting load @ 100yds and are pretty affordable (~30cpr). The 125gr Speer TNT are also worth looking at.

With CFEBLK the charges were so compressed that the very thin jacket was getting dented pretty bad with all of my seating stems.

Great info! Thanks. I will eventually be loading TAC-TX 110 gr bullets for hunting, but for now this seemed to be the cheapest way into a “good” hunting round. The Hogdgon numbers suggest a little heavier load though.

I’ve got multiple 10 round runs (per charge) starting down in the 18.4 range and intend to run it up to the max and maybe .1-.2 gr over (depending on OP indicators).

Morning All, Has anyone run Hornaday FTX 160gr? I know they are made for lever guns but I grabbed it on the discount rack at the local GS and was curious how they would run in my 300 and trying to determine a good OAL since they are a little fatter higher up on the bullet. from what I can find it looks like 2.12 looks about where I want to be but this is my first load not running off published data so i'm a little apprehensive of it. Any info or incite would be great. My 300 is a 10.5" BCA barrel 1/8 twist pistol gas system running H110 with CCI 450 primers.

I'm not sure why they bumped down their load data to 19.4 because it used to be 20...

I've been loading tac-tsx bullets with this for several years now and never had an issue with pressures. The accuracy is great in my 9.5" SBR, too, and average speed on the chronograph is around 2130.

Anyone tried 220gr Berry's plated with IMR 4227? I've got an idea where to start, just curious how people like that combo. Clean or dirty burning, accuracy, consistency of velocity?
Link Posted: 5/15/2019 4:26:53 PM EDT
[#21]
For anyone running 220gr Berry’s etc subs, what dies are you using? I picked up a Hornady resizer + seater for my lnl ap but I’m noticing it’s going to be shaving the crap out of the 220gr’s plating if I try to seat these bullets as is. I remember reading about someone possibly flaring the cases using a 9mm or maybe 357 ptx (powder through expander) for the Hornady powder drop, but when I just tried out the 9mm ptx the flare was pretty nasty and didn’t seem to help much. I’d like to keep the die count down since I’m using a rcbs lube die along with a powder cop die which is why I tried the ptx method for flaring. But really, I’ll swap dies out to get it to work reliably. Thanks for the help.

Tried out the 4227 and 220gr Berry's.

Seater die is a Forster micrometer die. I too noticed it was trying to seat hard in the brass. Guided the bullet all the way up until the chamber closed around it and supported it. Might pick up a Lyman M die to flare the mouth more.

9.6gr of 4227 at 2.1 COAL, CCI450 giving me 939fps with SD of 15 from an 8in SBR and a TBAC Ultra 5.

After posting my question earlier, I found from some dudes blog who ended up loading virtually every sub projectile out there for 300 black and he said the Lyman M die (there’s 2 diff ones so be sure to get the right one) made it so he could seat Berry’s and cast heavy weights. He also mentioned that using the M die drastically improved accuracy across all his 300 black loads, not just ones that were being shaven. I think he also mentioned using a lee factory crimp die, but I’m going to see how it goes with the Lyman + my Hornady dies. After flaring my test case an insane amount with that 9mm ptx, I seated a 220 and used the built in crimp in the seater and it’s holding fine.

Got my M die in and tried it out with and without expanding.

Expanding made velocities slightly less consistent. As far as I could tell, light crimp with FCD. Accuracy stayed the same I think (50yds with red dot and bad eyesight).

More or less crimp?

Expanded- 10 shot average of 927fps, 18 SD
Not expanded- 10 shot average of 925fps, 25 SD

Measured the distance between the ribs on a D&H 5.56 magazine and Lancer 300BLK magazine.

D&H center to center was 0.540
Lancer was 0.620, it has some flex so measurement was taken with light pressure.

Just a data point

When I shot the 150 grain plated bullets they shed a lot of jacket pieces in my suppressor. Could literally shake out small chunks of the plating. I wasn't pushing them that fast, either.  I won't be shooting more of them through my can.

Just finished the 2nd time reload of 50 of the Hornady 300AAC brass that I bought, this time with 125 gr Speer TNT.

Yuck. Neck is being pushed back into the shoulder causing donuts on the neck and shoulder bulges. I processed this brass start to finish taking care to do all the steps and do them correctly (AFAIK, as I AM a novice reloader).

The Starline I recently acquired (then loaded and fired 1x) has zero issues despite all of the same steps being followed on the same equipment. This makes me wonder if the issue is shoddy brass. Barring a real shortage, I won’t be purchasing Hornady brass again.

The Lyman M die neck expander will fix that. I'm loading on a 4 hole classic turret w/ an inline reverse rotation kit and have it setup Lyman M (load/seat primer on this step)-> Lee autodrum charge -> Hornady seating w/ microjust -> Lee Factory Crimp. Anytime I'm using flat based or coated bullets I use the Lyman M now days -- completely eliminated by brass shaving and shoulder crunching issues. Honestly can even get away without the chamfer step when using the M die w/ plated bullets. If I do crunch a shoulder with this setup it's likely from me getting sloppy with my bullet hold during seating.

Is there a specific one for the 300 AAC? Or do I need the 30 Carbine version?

I'm using: Lyman 30M1 Carbine Neck Expanding "M" Die. The neck expander ball can unthread from the main stem (it happened to me mid-session and my flare slowly changed every round) - recommend taking it apart and adding a little locktight, hasn't happened since.

Yes very excited about this.  It is currently the only loaded ammo i buy off the shelf now.

I can attest that it kills just as good as any other bullet I've used in the blackout.  I've shot two deer with this round and both deer didn't even act like they got shot.  Both times after i shot they bucked, looked around was like "WTF" and took off to only run for about 20 yds. then pile up.  I feel that they are not scared as there is no supersonic crack.

Not having any luck with these 217gr Gallant bullets. At 50yds they are printing over 1ft "groups". They do cycle reliably, and appear to be stable. I've tried 3x different 1:7 twist barrels. I was asking around and someone mentioned taking the calipers to one to verify OD - measuring 0.308in -- so I'm guessing they are undersized for cast/PC?

Am stoked about this. Been hammering Hornady every month to sell this bullet. Have about 20 boxes of the commercial stuff. Can't wait to reload this.

Got it set up and ran about 150 pieces through it. Have subsequently loaded about 40 of those. Worked like a champ. No more donuts. No more bulges.

Any way to keep the neck expander/fl resizing die from mangling the necks shoulders without having to dip every case mouth in sizing wax? I never had this issue with 556 reloading. Even keeping the outsides waxed/lubed isn’t enough, I end up being forced to use the imperial sizing beads to lube the mouths. It will collapse the shoulder about 1mm or so if I don’t (sometimes) and this absolutely jams up when chambering. It’s also really difficult to detect when this happens.

You might have the expander ball set too high in the die.

Another route would be to size and expand in separate steps. Either a Lyman M die as shown above or a Brownells expander die with a carbide mandrel (my preference) will work well.

I've yet to crush a case using a Redding FL die though, so I'm betting you have something else going on.

I’m running a Hornady die set and I have the ball up a bit since I don’t want to deprime at the moment. I I’ll lower it and test it out.

That sure does sound like the expander ball is so high up that it goes into the case mouth when the case is unsupported.

If you don’t want to deprime at this step, there’s a simple fix: take the depriming pin out of the expander ball.

Hornady’s expanders unscrew from the shaft, and their headed pins come right out of the ball.  That way you can size and expand at the same time.

How critical is case-gage testing when converting 223 brass to 300blk?

Using Lee dies.

With my Sheridian gauge, the brass drops right in, then stops just shy of flush with the gauge.

But they chamber just fine in my rifle.

I adjusted my full length sizing die to move the shoulder down more, but that hasn't seemed to help.

Finally got a chance to shoot some of the Nosler 220's for accuracy using my Micro 7 and Win 296. Last time I tried, someone else at the range was shooting my target and had me extremely confused...

Nosler load data is a bit off for bolt actions. You need to back off a hair more to stay subsonic.

Accuracy seems to be 2.5 MOA but I have some better cases I need to try out with a slightly thicker neck. All of them stabilized perfectly contrary to what many on the web purport to have seen. Vertical deviation is more than acceptable using 296. The group was nice and round. Other powders have given me some nasty vertical spread in the 16" barrel.

Another item of note - At the Nosler recommended COAL of 2.1" these jam the lands. If you hand load them definitely check your individual firearm. I should probably load a few on the lands to see if that improves accuracy too... My test loads today were .01" off.

There's still very little good information on these to include real world performance on game animals or gel testing. I may try to shoot a deer with one next week.
