Giving up

punisher12b · May 14, 2020

I have tried and tried, to reload 300aac a number of times,, I think im about to give up on the caliber and unload all my 300aac crap dies, brass, powder, projectiles..

and switch to 9mm since i seem to be on a pistol roll /and 300 subs are comming way down in price..

How cheap can 115/124 9mm be loaded for if life is working in your favor?

Don't give up!
What bullet, powder and load specs have you tried and what is the best you have gotten compared to factory?
I gave up on 300blk for a while and now I'm back.
I was trying to get good at subsonic and was getting no where.
Switched to supersonic and at least got respectable with both 110gr and 150gr loads

People better than I can give advice here if you list what you have and tried.

BUT, 9mm is much easier IMO.

you can always list your stuff in the barter thread.

300blk has a unique position of being very dependent on the gun itself, so all the information on the interwebs is mostly useless if not oblique unless you have the exact same hardware from the start. It's very frustrating seeing all the threads and load data, only to find that it doesn't work for sheit in your gun..

[edit] and to answer your 9mm question, I can average 9-10c per round of 9mm in supplies, not including the overhead of the Dillon, etc. I load for a Lage submachinegun so the overhead is about 17,000 rounds before break even. (or about 2 trips to the range LOL)

Tell us what twist you have, what gas length, and the type and makeup of the loads you are using.

Ballistic advantage barrel. 8.5" 1/7 twist

2.125 oal
8.3 grain lil gun
225 otm projectile
Fcd. Never wants fall into my chamber gauges

When I use 203 cast or 245 cast
I have tons of feeding issues would nose up and ftf

I didnt realize break even on 9mm was 17k rounds lol wow

I don't do reloading but feeding issues can often be traced to issues with the ramps, or the magazines.

You trying to use PMags?

John from MD · May 14, 2020

I don't shoot subs so I can't help with that part. However, I think your COL is too long for proper feeding. Try in the neighborhood of 2.030 and see how it works.

P mags. Usgi mags Lancer
I'll try shortening them

My 203 were closer to 2.003 id have to look at notes at home

Why I'm about to abandon after I load my 300 supers of varmageddons

And goto loading 9mm. In my pro1000

Figurd. Would be simpler.

Please confirm whether or not you're having any issues with factory ammo.

punisher12b · May 14, 2020

I’m trying to understand your issue. You had a failure to feed?

I’m new to reloading but I’m trying to understand trouble shooting options. Shortening the OAL is the recommendation of fixing the failure to feed issue. At least this particular issue? What’s a recommended starting length to shorten the cartridge? By shortening the cartridge, what other issues are/could be created when we shorten the cartridge?

OP, is it too soon to ask for dibs on any .300 blk equipment you have? [insert smiley here]

It's always best to start with the load data for the COL, THEN make adjustments if necessary. The reasons for and type of adjustments will vary depending on the firearm, cartridge, and projectile.

failure to feeds,,,( with my cast rounds
and getting solid shooting stable rounds..

I can not run test loads( my fault) i have an integral suppressed rifle so I cant remove the can.. and a bad load could murder my can... so i think ill abandon the caliber and shoot factory and just move on to reloading pistol

I understand.

punisher12b · May 14, 2020

I goofed once and shredded the baffel and end cap. Thankfully it was repaired and didn't need a new can

2.125 oal......Too short. Should finish around 2.250
8.3 grain lil gun.....Scrap the Lil'Gun
225 otm projectile
Fcd. Never wants fall into my chamber gaugesDoes the case drop into the gauge after sizing, but not after loading? What brand of brass are you using?

When I use 203 cast or 245 cast...Why so heavy a bullet??
I have tons of feeding issues would nose up and ftf....Sounds like feed ramp issues...can you give us pictures of the bullet nose after an FTF? Need to look for marks on the bullet nose.

I hand load all my subs.

Sounds like you have a couple issues there.

1) Quite possible your feed ramps don't 'mesh' properly. That's easily fixed.

2) There's no reason to load or shoot subs heavier than 225gr. Your COALs are a bit on the short side to boot. Should measure close to 2.250" with a bullet that long.

3) I strongly recommend scrapping the Lil'Gun for something else. A1680 for instance. It's still out there. Save the Lil' Gun, Win 296, and H110 for reloading supers. Hard as I tried in the beginning, I was never able to come up with suitable subs with any of those recommended powder.

4)I strongly suggest you prime all your sub cartridges with hotter primers. CCI#41 or I prefer Rem 7 1/2 Bench Rest. You'll get a more reliably consistent burn, resulting in narrower velocity spreads and better groups.

Curious, I have some Winchester 296 that I’m planning to load with some 147 grain bullets. I also read in another thread to use “hotter” primers. I recently picked up some CCI 450’s (magnum primers).
Am I headed in the right direction?

inkd · May 14, 2020

Another vote for 1680 powder and longer COL.

Are you shooting round nose bullets by chance? I have had issues with them, regarding feeding.
