  1. Currently I have a custom built (mostly by me) Kimber Pro Carry 10mm using a Fusion Firearms slide and barrel in 10mm.

    I'm pretty familiar with the 1911 as far as the slide and frame being nominal dimension to fit various cartridges. I know the 9mm, .38S and .40/10mm all use the same extractor and it will hold the 9mm in place on the slide.

    The one thing I'm not sure of is if the breechface on the .40 slide is the same as the 9mm Luger slide.

    What I'm trying to do is set my 1911 up to shoot 9mm. I have two choices: get a new slide with internals and barrel fitted or get a 9mm barrel fitted if the .40 and 9mm breechface are the same.

    I prefer to just get a barrel fitted, for simplicity and mostly cost reasons.

  2. I compete in a local club on college grounds on a college range (indoor).

    I compete with a Kimber Pro Carry converted to 10mm, bobtailed, with the firing pin safety removed.

    They know about it and allow it. But they are more about casual competition and not about hard and fast. They are not an official IDPA club, but are based on the rules, with local modification of some. They pick and choose what is enforced. From the quoted list above, they enforce all except the safety device one and they only allow a S80 type 1911 to be rendered S70 type. That's the line.

  3. Other powders besides PP can duplicate the pressure and velocity of other powder. PP is not a talisman for WWB. That was my point.

    My uncle is a ballistic engineer/technician with Olin's ammo division. Let me check with him and get back to you.

  4. You need to read my post again. I did not say that it was, what I said was it was the closest that a person could get to duplicate WWB.

    I suppose duplication and replication have differences.

    While WWB may be loaded with their version of Winchester powders, what I'm saying is weight for weight, charge for charge, you pull a WWB 165 TCN bullet and reload it with the exact same amount of PP, same OAL, you get the same velocity...

    Not always. See, the large manufacturers load to a certain pressure so their charge weight isn't used like the handloading community. They buy a powder and test the burn rate. Then figure out how much volume of powder will generate the pressure specification needed for the ammunition product to meet their performance. Then they load a volume of powder in each case and call it good. The handloading community is told that a grain weight of powder is a certain pressure, with a tolerance, when that's actually not the case. Handloaders adjust the volume to make a consistent grain weight of powder. The ammunition manufacturers adjust the volume to a specific volume of powder and couldn't care less about what grain weight the charge is. Mass does not equal volume and a volume does not equal a mass. Winchester loads a powder lot to a specific volume for that lot production of ammunition. The next lot of ammo could be a different volume of powder. Hell I've had the same exact box of ammunition have 3 different kinds of powder at 4 different charge weights, but all were the same velocity and pressure when they were tested.

    Now if you know which powder Winchester is using in their ammo <_< .....

    A few, yes. 9mm is loaded with WSF. .380 is loaded with W231 or AutoComp. .45 is loaded with WST. .40 is loaded with WST. .38 Spl is loaded with W231. 357 Mag is loaded with W296 or AutoComp.

    Besides, Winchester is loaded with canister powders, which may be a blend of powders, best suited for what they want for the round.

    Right, Winchester uses SMP brand powder. The same powder that is marketed under their trademark is the same powder they use in their ammunition. Difference being lot numbers. The lot you and I buy on the shelf are pretty consistent and are only a part of the entire spectrum of burn rate for that powder type. Being an OEM ammo manufacturer I have access to the "non-canister" powders that are merely different burn lots of the same powder that's sold to the handloading public.

    Look at this site.... http://www.bullseyepistol.com/reloads.htm

    Quote from the above website...

    Load for the 9mm Service Pistol

    Here is a 9mm load that David Sams has been using for testing Beretta 92 barrels and his completed guns that has been proven sub 1.5" groups at 50 yds is as follows:

    Starline brass

    115gr Hornady FMJ-RN bullet

    6.0 - 6.2gr Alliant Power Pistol powder

    Rem #5 1/2 SP primers

    O.A.L. -- 1.120" no-crimp

    Out of a barrel test fixture using Bar-Sto barrels groups have consistently run between .975" to 1.5" averaging about 1". Through David's completed 92F's, he claims that they have been running 1.3" - 1.5" as a reminder these are hand-loaded.

    Ok, so it's an accurate load. Am I missing something??

  5. I can tell when I'm sizing if it's a .380 or not. (9mm is tapered, .380 is straight. Straight wall in a tapered die is "loose" feeling.)

    I finally had a .380 sneak through while loading 9mm. I "found" it after sizing when it and the primer popped out of the shell plate while trying to prime it. Just for the heck of it, I tried to see what would happen if I seated a 9mm bullet in it and was surprised to see the bullet would slide right in and down as far as I wanted. 9mm and .380 are both .355...did the 9mm die not resize the .380 brass as much as a .380 die would?

    Correct. The taper of the 9mm case/die won't size a .380 case. It's "easier" to run a .380 in a 9mm die since there's almost zero resistance. It's even less than resizing a 9mm again (like resize, then resize again). That's how I can tell it's a .380 brass in there. I stop it at the swage station, remove, then continue.

  6. Negative. Winchester uses Winchester brand powders, known to the commercial trade as SMP powder. The nomenclature carries over, so Winchester 231 is SMP 231. SMP 296 is Winchester 296. SMP 224 is AutoComp. Winchester 760 (rifle) is SMP 760.

    Winchester is the only ammo company that markets their factory powder to the handloading community. It's not the exact same lot, but it's the same powder profile.

    Alliante Power Pistol is in the Bullseye family and I'll have to check my notes, but it's called Bullseye 88 or Bullseye 82.

  7. I found the primer pocket depth differs just enough on the stuff I have to where the swage rod will put too much pressure on commercial brass if it's set up enough to remove the crimp in military brass. I have to run them separately or risk damaging the brass. I tried all sorts of swage rod adjustments and just can't seem to get it dialed in right and proper.
