No OAL testing yet, because I was using my son's loads that ran good in their guns. We will see how it likes a couple of hundred 180/major loads tomorrow.

Wide45 I had almost a dozen failures when shooting 165s/minor at a IDPA match last week, most from slide lock, so I was easing it down just to troubleshoot it. USPSA Saturday with 180s/major, perhaps the slide was short stroking. The spring feels like the 12 in my 9mm 1911. The gun is still very tight, perhaps it will wear in. Charlie

None of the mags, including my boy's are tuned. Stock STI. Testing conducted with one round and full loaded magazines. The nose dips a bit so the round is horizontal. The rim never reaches the extractor. Not as many failures when dropping from slide lock, a bit better when a slingshot is used. Thanks Mike

I am working up major and minor loads for a barely used Eagle. Should the gun feed the round when the slide is eased down? Mine fails 10% of the time, my sons well used guns never fail with the same loads. It does it with all of the magazines and 165 and 180 grain bullets. I don't know what recoil spring is in it, waiting for a calibration pack.

My son has also broken several. He switched to a solid.

Yes. I was a skeptic until I disassembled my son's gun. Those things are great.

I am hoping the gumment adopts it to replace tie 9mm.

Nope, allowed

Take out the Springfield ILS mainspring and plunger, install a full length 17# or 19# mainspring to taste, and a generic plunger, get the cross pin that holds it together too. Add the extended firing pin. Charlie

Blue The critical parameter is where they contact. Even a poorly fitted barrel will contact the slide stop on the verticle face of the lug. A "good" one will contact on the top or 45 degree point. C

Sorry blue moon, but the lack of slide stop marks are just an indicator of a poor barrel fit.

I had (have) the same issue and made a chamber cast to validate it. I then made a fixture to hold and shoot the barrel and learned that my accuracy problems were not in the barrel proper. If I could figure out how to attach a photo I would show you a 1" group at 50 yards with coated lead bullets in mixed brass. Look at the slide stop pin and I'll bet you will find no marks from the lower lug indicating the barrel is riding the link into battery. I am almost ready to mount the full up pistol in a fixture to finish the testing. Then the fix is?

Similar problem with accuracy but I am continuing my experiments with bullet types, crimps, and charge weights. The chamber is the right length but throated way long. (I made a cast, nowhere close to SAMI.) I suspect that this is the cause. Any recommends for a know-good aftermarket barrel for coated lead bullets?

Chandler: Thanks a bunch. I tried the Precisions hoping they engaged the rifling better since they do not have a grease groove, but they did not help. I am talking 8" groups with velocities ranging from 800 to 1,100 fps. If the Raniers 147 JHPs would not shoot 3" at 25 yards off of bags on a side-by-side test I would turn in my man card. Charlie

I am at wits end trying to make this gun shoot moly-coated 147 grain lead bullets by BBI and Precision. It shoots 147 grain JHP Raniers, but not the solids, just fine. I use a wide bell, the crimp does not even mark the bullet when I pull them, and I cannot find any setback when I run them through the gun. I have tested a wide range of OAL with an equally wide range of WST loads. 4" at 25 yards would be great! I think the probelm is unique to this gun as everyone I know shoots these bullets. Thanks, Charlie

Solid 147 Raniers tumble @2% from my Springfield 1911 with 3.8 to 4 grains of WST OAL 1.15 and 1000 fps. Bad group. Going up to 4.2 did not help and the case is full. The hollow points do not tumble and have a good group. Same .376" crimp with both. Same seating die settting gives 1.13 OAL. Keep us posted.

Photo of S&W revolver FO sight in my Model 41 attached. File the sight tang straight, mill an 1/8" slot, glue it in.

I am not an expert on the topic, but I know spring engineering.... it is called coil bind.

Thanks horseman, can you give me a starting point and some chronograph data? And to saab, I'll get some Titegroup and throw it into the matrix. Charlie

I am struggling to find an accurate coated bullet (BBI) load after several false starts. Recommendations, with group size, please! Best so far is 6" @ 25 yards off of a bag under the butt. Thanks, Charlie

Darrell: I have been following your Bayou bullet 9mm work. I was about to give up on my Springfield 9mm 1911 untill I drove the BBI 147s over 1,000fps with 4.2 grains of WST. 2-3/4" groups at 25 yards with the butt of the gun on a sandbag. Half the size I got with 3.8 grains of the same powder. I am curious to see if you can duplicate this or is it limied to the Springfield barrel. Charlie
