first carbine unboxing

[floydthecat]

Thanks for clarifying, and for not having the patience to wait . This is very good news. Any unburnt powder issues that you noticed? I tried No. 7 in 45 clot in my SAA repro. It shot fine but left goey unburnt powder all down the barrel and inside the cases. Then again 45 colt has a lot greater capacity than 30 carbine. As soon as my ammo comes in the mail, I'll need to shoot a bunch so I have some brass to play with.

Pulled a patch thru the bore and inspected the action and fired brass. No residue or unburnt powder in the chamber, bore, bolt-face, or even in the fired case. I was a bit surprised even if I only shot a few.

Sounds cleaner than I've been able to manage with H110/W296. - Bob

I used the email form on the Accurate website to send my own inquiry. Searching my inbox for a reply showed it bounced back . I sent another through Hodgdon's site, which seems to have gone through. Not that I don't believe your results - it would be nice to know what the max/min safe loads are from them so I can safely work up what might give the best accuracy with No. 7.

Considering that the original powder for 30 Carbine was IMR 4227, you might find some of that left somewhere as it is probably rarely used today.

You are going to feel like a fool if you blow the bolt and receiver apart by using the wrong powder. These things were exploding with regularity when being developed until they got the case issue solved. I believe that there is really only one load bearing lug, the other is kind of a guide lug and probably is a safety lug as well. I bought carbine powder from Barnett years ago it was equivalent to Accurate 9.

I am not new to reloading and the dangers thereof. I have quite a bit of experience with #7 use in pistol-caliber carbine actions and know the limitations. One has to know how to read fired brass and understand the limitations of what the gun is capable of. The carbine action is proofed at a 140% overpressure load. #7 is a rather slow burning powder, so much so that it is recognized as the slowest powder that can be used in a 9mm action. One should always start low and work up. The only reason I tried this was from experience with 9mm. The 9mm and 30-carbine perform at comparative pressures and I’ve used a lot of #7 in 9mm carbine loads.

The point is understood and I think it is foolish to dump a charge in a case without having some experience and understanding about what it might do. Throwing in a handful of something like bullseye or red dot would be seriously stupid.

I am a true believer that one should never trust and shoot anybody else's reloads and that applies here. I don’t ever recommend a reload to anybody and don’t now.

Blindly dumping an unpublished charge into a case and firing is one thing - but we are certainly not discussing or promoting that here.

Very good advice.

I'm not saying that you are a novice or questioning your judgement, but consider why does a reduced carbine load of H110 cause pressures to skyrocket? Why does a normal 9mm bullet loaded to operate at say 28,000 cup pressure and the same load in an uncannalured case rise to 62,000cup when the bullet is pushed back into the case .030 deeper? (Straight out of the #10 Speer manual)

Below, excerpted from a 2010 CMP discussion of the subject, basically an autopsy of a busted carbine using slower powder.


"Other powders: Yeah, there are some that are a close match. The ones with a seemingly LOW pressure achieving STANDARD velocity are a problem in carbines. A low overall pressure achieving the standard velocity means a slow burning powder that extends the pressure curve father forward and creates a higher than normal port pressure. May not push on the bolt/cartridge case head hard, but it pushes on the gas piston harder than expected and slams the slide and bolt with more vigor than normal. If you can hear, you hear the wack/wack instead of a schuup/schuup sound. Using those slower powders may well not be an advantage if you understood what is going on inside the barrel and gas cylinder."

It's just information, may help, may not...

I never did understand why some people want to reload their own ammo. at home where it is so easy to make a mistake either by by equip. failure, laps of attention, or just simple incompetence when they can buy the ammo. from a co. known for it's excellent ammo. for many years.
Seems like some things [esp. ammo.] should be left to the experts, jmo.

I would agree with that 100% if the ammo situation was the same as it was pre-covid. When you go to purchase ammo in this environment, get ready to bend over. I’d rather be reloading for about 20-cents a round as opposed to buying at a dollar a pop. Of course, reloading supplies are expensive and scarce now also, but if one was lucky enough to have the supplies pre-covid……he is shooting cheap now days. And…it’s fun too!🤩

equally dangerous to navigate rush hour in the morning...doesn't mean I'm going to take the bus everyday. shooting factory ammo can be dangerous too. many posts on here with "accidents" - I'm too lazy at the moment to find the post, but a guy blew up his Garand with Cabbala's herters.

for me anyway, others may feel different...it's almost all about quality control. I am an expert, I can do it better than an automated assembly line that only spot checks lots, and with greater consistency from round to round. I trust myself and my attention to detail. I do this (attention to detail that is) for a living. I get that other's are not confident in their ability to pay attention to detail and process and don't want to load their own. I generally get 30%+ better accuracy out of my loads than similarly priced factory loads.

my neighbor also cries "cleaning your gutters is best left to the professional", but I do this better and more carefully than them too.
