  1. Yes, you can get an extra round into the magazine if you thin the follower and allow it to go further down. But such follower normally won't have the ability to push the slide stop up. Even if it did, once you make followers very thin, you don't want them to interact with the slide because they could potentially twist or cause other issues. A tall follower sits very firmly inside the magazine tube, the thin one so-so.
  2. You normally don't mess with the slide stop, you modify the follower. The flat followers will allow the spring to bottom out, but at the expense of not having the bulk to push the slide stop up on the last round.
  3. Downloaded - the last thing you want is to slam the mag in on reload only to have it pop out on the next shot. If it's tight, it's not worth the risk. Even the initial magazine, where you can force it in, is rarely worth it unless your stage design really calls for *every* single round to be used prior to reload. But if you run the gun dry, you'll have to rack the slide as most Limited guns don't slide lock on empty; a mess .
  4. It's hard to ban a concept such as "retreating" in a sport that is by nature freestyle (principles of USPSA, item 8). I doubt it has ever been "banned," but I might be wrong...
  5. To answer your question, those divisions will lose participation, but they should remain in order to allow people to play in them. There is no benefit to trimming divisions, it's literally just a checkbox in PractiScore. Let people shoot what they like. The only way to have more participation is to have hardware-specific matches so the guys can shoot less common divisions without having to sacrifice their primary division. But this is problematic at local level as people might choose not to participate, or might not have the gun for such divisions.
  6. The dot is becoming to pistols what the LPVO (or the dot) is to combat/tactical rifles - something that you expect on a gun. How many iron-sighted ARs are out there (by that I mean "how many are run in any competition where LPVO is allowed")? That's where the handguns are headed, albeit there will always be much more room for iron sights on a handgun due to the typical engagement distances that do not *require* a dot. But as a matter of preference, dots are here to stay and they will only grow.
  7. As long as the Open guys get the top overall, someone will want to race that horse. It's the slower divisions that might die off eventually...
  8. Your assumption is that you're getting an exact zero at 10 yards, which fails to account for an inch or so you could be off in either direction. The best test is to take a gun sighted in at 10 yards, shoot off of bench at 25 or more yards and look at windage - you'll see how quickly "not being exactly at the center" propagates. Now consider that you have similar error in elevation at 10 yards, and you might become more critical of the 10 yard zero :-). Remember, every inch you're off at 10 yards becomes 2.5" at 25 yards, which is in addition to the bullet path offset due to the barrel pointing slightly up. When you combine the two, to get a good hit on a 6" plate at 25 yards you would pretty much have to be dead center with your aim, which makes that target *much* harder than it needs to be.
  9. Beware of the unintended consequences. The rules as they are pretty clear and clean and I wouldn't touch them, at least not due to this particular example. That doesn't mean every situation is easy to score, but that's not about the rules, it's about reconstructing what happened with the bullet.
  10. But that's how it currently works. The rules in 9.1.5 state that only "partial hits" can count on downrange targets, so it's only about the edge hits. A full diameter hit doesn't score/penalize downrange no matter what.
  11. In this case, I would argue (and score it) as a pretty clear NS. Whatever is in the jacket *in the end* doesn't matter as the lead could've been inside as well while only the light jacket stuck to the target. The jacket is part of the bullet and this is NOT splatter (a full diameter hit on a metal target or rock and the non-scoring fragments end up all over the place). Here, there is a mark on the metal plate to prove only a partial hit, so the rule 9.1.5.3 applies to whatever chunk of the bullet went down range, as long as it can be determined that it was a part of the bullet, which the jacket proves.
  12. This was addressed by the NROI some time back, where a bullet grazed the face of the turning target that was close to 90 degrees by that time. The edge of the bullet cut a long gauge in the front that was deep enough at one point to see-through. As long as there was a hole and at least *some* part of bullet went through, it was a hit. So, in this case it's a hit (separate issue from whether jacket is part of the bullet).
  13. In practice, even "hard" hard cover will make the bullet hole recognizable. If you end up with shotgun pattern, it's likely rocks and dust from a bullet that hit the ground. But if you end up with a visible hole and you know that the shot went towards the target, it's most likely a hit unless you can determine it wasn't. Rule 9.5.5 gives you cover in case you believe it's a miss. It lets you use the "presumption" to score it as a miss. But as an RO, it's your job to score correctly. And, if you can't, it's reshoot anyways...
  14. If the bullet hits the target down range, it's a hit. Rule 9.5.5 does not *require* any particular shape, it only talks about the presumption based on what is typically on the target. If you really have unpenetrable hard cover and it distorts the bullet, it's up to you to determine whether what's on the target is really bullet or splatter. If it's bullet, it's a hit, regardless of the size of the hole (and especially regardless of the grease ring, which is just an example of how one can decide it's a bullet and not something else). In the end, the scoring rules is very clear - if it's part of the bullet, it's a hit, otherwise it's a miss. It is *you* (as in RO) who has to determine what really happened. And, if you can't determine that it's a bullet, it's a miss.
  15. Wow, good to know - normally, a squib will get stuck close to the breach and won't let the next round chamber... But having a lower caliber brass pushed into the chamber... scary!
  16. L/O was introduced and became a very quick success precisely because there *are* differences that matter. It wasn't just a bunch of C/O guys signing up for L/O with the gear they were already using.
  17. L/O is to C/O what Limited is to Production (less major). Merging L/O and C/O makes as much sense as merging Production and Limited. The only question that I could foresee is whether to allow major scoring in L/O, but even that seems highly unlikely given the trends toward the unified service caliber of 9mm for semi-automatics.
  18. Being target shooter explains your preference for "balancing the ball" (#1 sight picture), but you have to remember that it only works when the "ball" is fixed angular size. Have a target of different size, or at different distance, and now you have to estimate how much to hold under. Yes, #1 is superior for target shooting at *fixed* distances and *fixed* target shapes (well-defined size of the inner circles) precisely because it's more accurate to have the ball touch the top of the sight (and sometimes even to have a sliver of white between the ball and the sight) than to determine the center of the ball, but the moment you get into action shooting at various distances, #1 becomes highly suboptimal and much worse than #2.
  19. Usually "out to in" but this is also a consequence of the slight natural cant when shooting one-handed, where the gun recoils towards the next target naturally. Don't stress, if opposite makes more sense, e.g., shooting as you move in/out of position, there is nothing wrong with it either. When shooting one-handed you primarily lose the ability to control the recoil effectively, so you have to wait for the sights to get back on target no matter what.
  20. Sighting in - at 25 yards, sight picture "2." It gives me the point blank range out to any distance that I'll shoot in competition.
  21. It doesn't, the barrel points "up" so the bullet doesn't start dropping until it reaches its apex. The vertical component of velocity starts decreasing (velocity changes in the direction of gravity pull, so absolute value decreases), but until this velocity is zero the bullet raises.
  22. I'm pretty sure all my AR-pattern rifles "fire" with the flag in. By "fire" I mean that the hammer drops, even if it doesn't actuate the firing pin. The design of the AR-15 is that the bolt must be fully forward (in battery, locked) before the angle of the hammer is such that it can reach the firing pin. But the hammer will drop when the trigger is pulled way before the bolt is in battery.
  23. That's how it works - you pull the bolt back twice, once to show clear followed by closing it and pulling the trigger, then you pull it back to insert the flag. You can pull the trigger on the flagged PCC if you want, but the question is whether it's a good idea or not. If you do, the hammer will be resting at an angle against the back of the bolt because the bolt won't be in battery due to the flag. The falling hammer will also hit the bolt at this angle instead of hitting the firing pin. If you just keep the hammer cocked, there is no harm whatsoever because the springs weaken from contracting and expanding, not from being either contracted or expanded. Compare to magazine springs and endless discussions about whether it's acceptable to keep magazines loaded...
  24. The problem with "gaming" was when it did matter, such as when, e.g., the wording on activators was that they "must be activated during the COF to avoid a procedural penalty." Since the COF does NOT end with the last shot, there was a way to activate them AFTER the last shot and not get penalized. Combined with the support structures of walls being part of the shooting area, there were some serious "misuses" of the rules. While it was legal at the time, it got changed by changing the rules, the way it should be handled (and not by denying the shooting plan that is by the rules). In fact, the rules have evolved to SIMPLIFY starting positions by removing default position and subjective terms such as "relaxed at sides." The idea is precisely to prevent these types of issues, where anyone can start however they think it will help them. In the end, the guy who shoots the most points in the shortest time wins. As it's always been (well, except for those times that required rule changes, but that's neither here nor there) ...
  25. ^^^ This. Plus if the WSB doesn't specify it, it is allowed and up to the shooter to try whatever he wants.
