  1. The 147s can be problematic. The length can inhibit function in tight chambers and short chambers. They can raise pressures and (as mentioned) can be hard to make accurate sometimes. 

    That is the reason I went to 135s. They are a good blend of function and accuracy and recoil/flip. If i am out of 135 I load 125, same charge and COAL,

    I also shoot .357 or .358 in the guns which allow it. Revolver mostly but I have a couple autos that like that diameter. My PCC wants only .355 but I just switch to them at loading. I use the same charge/crimp whether .358 or .355.

  2.     A long time ago I discovered that different powders yield different muzzle rise arcs. I called it 'recoil arc' because back then ('83ish) there was no information aside from waiting 1 or 2 months for the magazine to come. I found that certain powders gave a quick snap of rise and others gave a slower more rhythmic arc. Recoil (to me anyway) is not crucial because that's what pushes back into the hand. The muzzle rise (or jump, flip, whatever) is what slows down the 2nd shot.

        Nowadays with all of the metrics on shooting it's easy to forget the 2 things that really matter; are you sights on the target when you press the trigger and did your trigger press disturb the sights? The muzzle should come back on target (or on the next target) on it's own. 

        FWIW my testing (and many others) says that the same PF with a heavier bullet yields less muzzle flip or a longer, slower recoil arc. In the case of my revolver in SC I have found that a 96gr bullet and a light load of Win 231 yields very little recoil. I think that's due to a 50ish oz gun more than the explosion within. That's not science, probably, but that's what 40 years has shown me.

    I can usually tell when somebody is shooting 115s in their 9mm. The report is sharper. When you watch the muzzle flip you can usually see the quick rise. Kind of like a compensated gun compared to non-compensated. My load is actually the same in my 929, autos and PCC for 125 and 135 bullets. Makes PF.

        Works for my guns, loads, purposes. YMMV.

    CED IR. 60 degrees. Light front wind.

    147gr JHP, 1.16, same brass/primer/bullet, 2011 bull KKM and never cleaned barrel.

    821, 834, 844, 858, 863, 877, 886.......? Upwards?
    My first shot on the chrono for years is always the slowest but this was odd. Wasn't set back. I check that. Doesn't even hit the ramp with a nose anyways.

    Here's an even odd'r part:

    147gr RN, Blues, 1.17, samsies....
    910, 908, 914 - SD of 6?

    Any insights would be helpful!

    Are you wondering why the Blue bullets show more velocity with the same charge than the jacketed?

  4. I just had TK cut my 686Plus for 9mm. I use the same loads. About the same length/weight but only 7. The 686 moons are only .022 or .025 so they are weak. The TK moons are .035. Nice.

    I use it for practice to keep from wearing out the old fella.

    Or the 929!

  5. But on the other hand, my 929 was just like any other S&W revolver. A little work and a lot of testing. I tried about 4 different loads I had for various 9mm and the 'hotter' ones stuck cases. My normal load was fine from the start.

    Never shot factory through it. My crimp doesn't let the bullets creep. FC brass and Federal primers.

    It has never shot a factory load. I reload so why bother.

    25K the first year and 23,500 the 2nd.

    BossHoss has done most of the work (trigger, tune, bore the end cap) and the gun now has something around 75K and still going.

    Wish I had 2 or 3.

    BTW a S&W former factory shooter told me a couple years ago that he has 11!

  6. Awesome! Good for you!

    When I had mt 1st eye done I turned on a baseball game that night. I called my wife in and said, "Look how green the field is!" She said, "They are always that green..."

    My right eye ended up a bit better than 20.20 and the left is 2-/40 uncorrected.

    Like hiker88 said, I wish I had it done sooner!

     

  7. I use the same powder for all of my loads. Win 231. I vary the charge a bit for different weight bullets to stay around 130PF. I shoot 3.5 gr with 125 and 135 and 3.2 with 147 although I rarely use 147 anymore.  My 6" 1911 using 4 gr of 231 was getting 135 PF out of the 6" barrel. 147s don't shoot well in shorter chambers from what I have found. 135 shoot much like 125.

    I use 10 or 11 lb recoil springs which lessen the muzzle flip a bit.

    Perhaps, being an old Open shooter, you're not exercising "visual patience" at a rate needed for the non-compensated gun.  Your Open gun undoubtedly tracked differently than this one.  Your brain is screaming "COME ON NOW!!", wanting the dot to be back where it was, but physics precludes that.

     

    An additional thought:  147s at a low Power Factor are very "lopey", IMHO.  The gun feels like it takes forever to cycle to me.  I run 124s at about a 132 PF.  They are snappier, but I don't feel like I am waiting on the gun as much. 

     

    With folks that I have coached, I have found the same to be true in former Open shooters and with younger shooters who grew up playing video games.  They both have very fast eye speeds...which also explains the popularity of CO & LO with the young people.

    My experience with the 147s is similar. I experimented in my 6" 1911 and to go down in PF I can actually feel the slide cycle at the low point. I shoot almost all 135 gr Bayou now. The recoil impulse is a bit quicker which brings the sight back on more quickly. I really like the 135 for the 9mm. I feel that it is the perfect bullet for me! YMMV.

    There is a combo somewhere that will work for you. Keep testing and you will find it.

  9. I have a 6" 1911 with a tight chamber. I have to run my reloads at 1.060 or so. I have tested up to 1.100 and down to 1.020 and the shorter always work. At 1.100 they will sometimes not feed correctly depending on how hot the gun is, dirty, and I guess other factors. Try shorter (maybe 1.100) just for grins.

    BTW I shoot the same OAL in all of my 9mms now, including revolvers.

  10. My LnL shows a split case as it rides on the feed rail into the 1st stage. I keep a half dozen good cases on the bench and replace as necessary. I don't case check except to (about once a year or so) separate the FC (revolver)from the range brass (auto) that gets mixed in. Moon clips negate most of that.

    I check about 5 or 6 in a case gauge every hundred reloads.

    Haven't been casing anal since the old varmint/benchrest days.

  11. I have a rimfire rack. 6" plates. It sits behind the 8" centerfire rack. Lighter plates are easier! 1/4 inch is perfect.

    They all can be knocked over with rimfire. You can drill and tap a hole centered with the bottom of the plates to lift the front and make the plate easier to drop. It really only takes about 1/2 to 1 turn. I used 3/8 course thread bolts. Too much adjustment and the vibration will "volunteer" the other plates. Fine line there. I have seen a couple that have a small piece if flat steel welded to the bottom front for this adjustment. On my bowling pin rack (8 steel plates/pin shape) I put a 2x4 under the front legs of the sawhorses to tip them back for rimfire. That works too.

    You can engineer about anything you want. The problem comes when you want to use it for a large number of shooters (match, etc.) because you don't want re-set issues while paid people are waiting.

  12. Speaking weight from a revolver perspective, I tried both.

    My TRR8 was really light. I left the rails on for the weight. I found that I was swinging past a lot of targets. Too light for that! USPSA and plate matches it was great but I was opting for 1 gun for all.

    I got a 929 and that was the ticket for me. Heavier swings smoother (for me) and settles faster.

    The rimfire rifle guys are Dremeling weight away all the time! My RFRO gun is 4 1/2 lbs. Some are lighter.

    A good friend bought his wife a Ruger MKIV lightweight thing. She hated it! Made him sell it and buy a full weight model.

    Of course test because YMMV.

  13. Yeah, they have been down a little on shooters since Covid. Last year I think I read 500 something rather than the high 6oos some years back.

    The registration used to fill up in less than a week. Now they have open slots as did last couple years.

    I love my moons. Usually find them by my feet and sometimes 1 in front of the table.

    The plastic tub is probably good, although I would be afraid of my reloads slowing down just thinking about it!

    Wish we could have Jeff make a whole squad of revo shooters! Fun times!

    Thanks pskys2! That is a very significant crimp, we appreciate the data. She is considering getting her Ruger cut for moon clips eventually by TK. We might mess around with 38 short Colt once we have the clips all setup. We don't want to chase brass while using speed loaders at this point.

    The guns is not cut for moon clips yet. She will be cylinder dumping loose cases. Might as well use 38 Special. Will be cheaper that SC.
