First, I'm pretty intimately familiar with the 228-1R. And no, it ain't in any way a duplicate of factory ball. Look a little more closely. It has more bearing length and a shorter nose length than regular ball. 1R means 1 radius ogive. Ball or 230 FMJ's are two radius ogive.
This is the help I was seeking!
Your eyes aren't attuned to small differences in bullet appearance yet, and how that affects proper overall length and functioning. We'll get you up to speed.
Yeah, I can see what you're talking about now when I compare them side-by-side.
Don't set its overall length by a milspec round. The short nose of the 228-1R means that if loaded to the same length as factory ball,
too much bearing surface will be out of the case, and the gun won't lock up because the bullet will hit the lead (rifling origin) and prevent full chambering.
I think this is my problem. It makes the most sense given the "symptoms".
"The pistol jammed with four different factory loads, then locked up tight with my hand-loads using my cast boolits."
Ding Ding Ding!!! Just what you found to be true!
"I tried chambering another of my cast rounds after the WD-40 and it's stuck again. I'm thinking there's something else going on here."
Once again, confirmation of what I've just stated.
Please post your overall length.
OAL for factory stuff (Winchester 230 gr. FMJ cheap stuff - 1.265. My hand-loads with 230 gr. hard-ball: 1.260. The cast boolits: 1.255. Maybe I need to seat deeper?
Correct, for my guns to allow the cartridge to chamber properly, is in the range of 1.210" to 1.220."
Second, what magazines are you using? Please don't tell me they're Shooting Stars. Or Triple K's, or some other gawd awful magazine. Shooting Stars are predisposed toward problems because of an excessively weak magazine spring.
Para Ordnance sent us their own hi-cap mags, and the springs are so strong I am unable to load them to their capacity without the aid of a speed-loader. And I can CRUSH most men's hands.
Triple K's? Well, one look at those and you know the "genius" who designed them didn't know a damn thing about a 1911.
Telling us the exact magazine and type, and the shape of the feed lips. A picture would be helpful.
Third and finally; describe the
exact cartridge position when it jams; whether the case rim was fully under the extractor, case nearly in the chamber, etc. Just saying "it jammed" doesn't convey any information. Describing the
exact cartridge position when it jams will give big clues to what's causing it.
The gun attempts to chamber the round, but fails to move to full battery position. The slide is roughly 1/4 inch to the rear and will not move either forward or backward with any amount of convincing.
Without those "big clues" we will find it harder to diagnose, and a "good break in" might not be the answer to the problem.
A gun that suffers multiple jams right off the bat doesn't need a "good break in"......what's causing it is so out of sync that shooting it more ain't gonna help it start functioning better.
You problems are a lot different than what a simple "wearing in" would solve. A "break in jam" is a few minor hiccups, not a situation where it malfunctions as often as it feeds.
