    I like TC or similar flat-pointed bullets because I can load them much longer than a round-nose in my guns with shorter chambers.

     

    Weird. For me it has more to do with the bullets ogive than the point/meplat. My situation is the exact opposite. The FP I load have a wider ogive, which means they engage the rifling sooner, so I need to load them fairly short (1.09) for my CZ Shadow. Generally, I can load much longer with RN bullets.

  2. I use Dillon dies to load 147's without issue but the bullet I load is RNFP so the round nose stem doesn't make contact with the point/meplat of the bullet. I would take out the seating insert and make sure it's clean. Also, you can probably fill the hole in the seating stem so that it won't mark the bullets but I would make sure the insert's clean first.

  3. Are you sure it's not your sizing die. Regardless, brass flecks are getting embedded in either your sizing die or the FCD. Grab some steel wool and clean the ring(s) then polish the ring(s) with Flitz or similar.

     

    Here's a picture of what to look for...

    My BHP showed some difference in accuracy, but I was forced to go with the

    OAL which fed 100%, at the expense of accuracy.

     

    Obviously, it was an acceptable trade off - not an unacceptable loss of accuracy.

     

     

    My BHP showed no difference, just like all my other handguns. I'd chalk it up to dumb luck.

    Huh? Coke bottle effect in 9mm is normal. I run 7-8 lb springs in my Open guns and I have never used roll sized brass.

     

    Yeah, I don't know what mechanoset talking about. To be completely honest I don't think I understood a single thing from his post, lol.

    I tried your little test the other day, but my BBIs won't fit into a fired case.

     

    Weird, using a fired case works for me even with .356 bullets. Regardless, the other way you can do it is to load a round in the press really long and continually seat the round shorter until it will plunk and spin in the barrel. That will give you the max OAL for that barrel/bullet combo. Don't forget to make sure they'll also work in your magazine.

  7. Nothing will happen and you'll see a negligible difference at the chrono. More importantly have you push tested the barrel(s)/bullet(s) combo to make sure that length will work? What about the magazine(s)?

  8. I load to 1.09 for my Shadow with a FMJ 147gr bullet. Don't worry about the short length, use the OAL that works for the bullet/barrel combination. You might be able to drop the load a little but I would chrono first to see what you get before modifying the charge. Prior to getting my Shadow I loaded the same FMJ 147gr bullet to 1.135 with 3.6gr of Titegroup. When I shortened the OAL to work in my Shadow I really didn't see a difference at the chrono, maybe 10 fps, which is negligible.

    I’m getting the impression the short OAL is only with lead/coated Bullets

    Anyone having to load short with FMJ/plated?

    The projectile's profile is what matters. Regardless, load them short(er) and live life happy.

     the  marksman barrel is  excluded  of  the conversation.

     

    the  ideal  AOL's  for  the  glock  polygonal  barrel  whatever  the  caliber  are  well known since moons  and moons.  glock barrels (polygonal rifflings and  chambers )   haven't changed  since 4  generation of  guns.  the  marksman barrels  are  brand  new on the  market,  so  far  only  the G17  gen 5  is  on the market  right now.  so obviously  we're  talking about  subsequent  productions which  means the polygonal  barrel.

    <

    ...and  no,   gen 2-3-4 chamber's  specs  haven't  changed  too  along the past   couple  decades ,  and then   won't show  such  variations  from gun to gun   that you  absolutely  need  to  run a plunk test ( unless the use  of  different bullet profiles))

     

    1) It's OAL, AOL was an internet service provider.

     

    2) The OAL is projectile/barrel/magazine dependant not firearm specific.

     

    3) You specifically mention the G17 and now state that since the only Gen 5 available is the G17 (which is also incorrect) that we're supposed to know which generation you were referencing?

     

    4) What makes 1.13 better for a Glock than 1.09 or 1.10 or 1.12 etc.?

    That's dangerous advice. Reducing OAL does cause pressure to increase. This is not a proportional equation though. some times it's exponential. I've watched several guns blow up and it's heart breaking.

     

    I don't believe you Chicken Little. Start at a minimum charge and work your way up. As long as you don't do stupid everything will be fine.

     

    Even when you do stupid...

    SO-at that factory 9 oal is 1.150 ish--- and they worked- could be bullet profile!

     

    Not could be, always is.

     

    Loading short shouldn't be feared. Also, the only time I worry about compressing a load is when it's so compressed that it doesn't allow me to seat the projectile to the desired length.

    consensus  for  G17-G34    is  1.130  .

     

    1.145  is  considered  quite long  given the  fact  that 1.169  is  the max  AOL  specified  for  the  9mm round.

     

    Consensus is you should always check with a push test and find your own OAL. Take the new Gen 5 for example, your "consensus" 1.13 might not pass a plunk test.

    It's not a powder issue. Could be: too light of a mainspring, high primers, too hard primers (rifle instead of pistol), short firing pin, etc.

     

    Yup, I too vote for one of the above being the culprit.

     

    I would lean towards it being a firing pin/spring problem. You've already somewhat eliminated a problem with the ammo, since it functioned properly in another firearm, that leaves you with a Springfield 1911 problem. What brand of primers are you using? I bet they aren't Federal...

    Trace and I spoke about this load before he tried it, and it's largely what I load for major matches.  For practice I substitute various less expensive bullets, but is otherwise the same.  I have tried it in many, many guns and not run into a problem with the bullets hitting the rifling, and I've never had random hot rounds with it.  I've got hundreds of rounds of it over the chronograph to support that as well, so I'm thinking it's a random oddball case.  

     

    Although you may be correct what does running it in your gun(s) do for him? I run my 147gr load with an OAL of 1.15 in many firearms but that doesn't mean it will work in a CZ or PPQ. It's quite simple actually. We can guess until the cows come home but until he starts eliminating potential causes (like doing the push test) and provides us with more information we're just throwing darts.

    I don't understand your question.  1.125" is where they are.   They fit my gauge and my barrel.

     

    I'm not sure what you don't understand. You need to find the max OAL for the projectile/barrel combination. I load a particular 147gr projectile at 1.15 for my Glock but my CZ Shadow won't accept anything longer than 1.09 (same projectile).

     

    Do this...

     

    There are several ways to do this, but here's my method.... Fit a new jacketed or plated bullet into a fired case. (No powder; fired primer.) If you try 2 or 3 bullet/case combinations you'll end up with 1 or 2 where the bullet is a snug "push fit". Set the bullet out to an OAL of like 1.300". Any OAL longer than what you need. Working with your barrel REMOVED from the gun, slide this "test cartridge" into the chamber. The bullet will slide back into the case until the mouth of the case comes to rest on the end of the chamber. Now, slowly and carefully withdraw the test cartridge and measure its new length. Do this a few times to make sure you're getting a proper measurement. That measurement is your exact chamber length for that bullet in that barrel. Now of course we need a set-back distance off the rifling, so subtract at least .015" from that number to obtain your maximum OAL.

  17. OAL too long.

    Loaded ammo falls in and out of the chamber/barrel with ease.

     

    Every single round? I think the OAL on some rounds are too long. How did you obtain the max OAL for that projectile/barrel combo?
