  1. A bit off the subject of this thread, but take a look here for a mag system... http://www.sharpshootersupply.com/index.html
  2. Are they? I need to turn my 3gun M2 blaster back into a hunter, at least occasionally. Can't find the M2 mag tube cap (but I have the spring ). Located an M1 cap, so the question is will the M1 cap fit the M2? Thanks in advance if you can help...
  3. Nope. At least not in USPSA, sight pictures are not forbidden unless there are psted match rules prohibiting it. In IDPA they bing you for a procedural. At a minimum. It could also earn you an FTDR. Site pictures are philisophically in the same class as round counting and individual walkthroughs. Dry firing may cause the SO to have a heart attack
  4. Is that an AD or an ND!? Anyway, thanks for fessing up. OK to make and admit mistakes, not good to hide them. I was worried Homeland was after us, or worse we were going to be hijacked.
  5. OK 45 second on the Google calculator and I got the following: A baseball is no more than 150grams, which is about 2315grains. For a 125000 pf, I would need to throw it about 54fps (125000/2315 = 54) 54 fps is about 37 mph. I can do this! (I was clocked in Highshcool at about 60mph) Next time I get to the range, I'm taking a baseball. I wonder what the president of the pistol club will say if he sees me throwing a baseball at a popper or plate rack! Probably laugh because I'll have to throw a dozen times before I hit the darn thing. My gut tells me the baseball will take the plate over faster than my 9mm loads at 130pf. Now we're having fun! Ask that physics major what he thinks...
  6. Sorry, got this backwards. At a given powerfactor, the lighter bullet would have more KE than the heavier bullet. KE is 1/2 x m x v^2 (squared). KE is more sensitive to changes in velocity than in mass. My quick calculations (on the back of my electric bill) show that the lighter bullet (at a 125pf) will have about 25% more KE than the heavier bullet at the same pf. The other part of the story is momentum, which is m x v. But we already know it is the same since the powerfactor is the same (yeah I know, weight and mass are not the same, but it works for this discussion). It is my observation as well that the heavier bullets tend to do a better job knocking things over. But why? It has to do with the time the bullet spends pushing the target (longer with a slower bullet) and, with the amount of energy used to deform (destroy the bullet). A small fast bullet (i.e. 9mm) is completely destroyed when hitting steel (ever find anything other than an occasional jacket?. Big slow ones are not destroyed - you can regualrly find 45's especially FMJ after they hit steel. Now I'm getting interested. I wonder what speed I would have to throw a baseball to get a pf of 125,000. Wonder if it would do a better job on a popper than a 9mm? Hmm...
  7. I use the heavier SG sparingly on my Savage. Works well. Doesn't seem to be a need to really dope things up.
  8. I haven't tried in 5 divisions, but I have shot 3 divisions. I'm in the camp of classifying 1 down in other divisions from your highest. Much of the skills (both the classifier and match) that put a shooter in a class are very much transferrable from one class to another (Indian, not the arrow). This is especially true of match skills (very few matches are won or lost on split times being 10% different, except maybe between Burkett and Langdon). Lots are won or lost on procedurals, mistakes, approach to shooting a stage, etc. That stuff translates. Split times are equipment dependent and don't translate. Sorry - continued the drift...
  9. Stick with the regular AR. The others will cost you a pile - the price of being an early adopter. Don't remember if you handload, but I wouldn't touch either unless you did (or had a money tree in the back yard). Get good with the regular AR and then think about switching. You always need more guns. Here's a paste from the bushy website about .223/5.56 .223 Remington or 5.56mm: We've had numerous inquiries about .223 Rem. versus 5.56mm NATO ammunition. The short answer is that all Bushmaster barrels are chambered for the 5.56mm cartridge. Most of our barrels are stamped 5.56 NATO - usually just ahead of the front sight. Despite the fact that our Lower Receivers are stamped CAL.223-5.56MM, our chambers, barrels, and bolts are designed to withstand the higher pressures of the 5.56mm cartridge. We do this for the safety of our customers, and because our rifles have always been built following the military pattern. In any of our barrels, both the .223 Remington and 5.56mm NATO cartridge can be fired safely. So, what’s the difference between the two cartridges? They have basically the same exterior dimensions and length, but the 5.56 is usually loaded to produce higher velocity and chamber pressures. It has thicker case walls for the extra strength needed to handle those higher pressures. The difference comes in the chambering of the rifle, and that difference is in "Leade" (more commonly known as the throat) which is the portion of the barrel directly in front of the chamber where the rifling has been removed to allow room for the seated bullet. In a 5.56mm chamber the throat is typically .162" - in a .223 chamber it's usually .085"(about half that dimension). The result of firing a .223 cartridge in the Bushmaster 5.56mm chamber is a slight loss of velocity when measured against the 5.56mm cartridge. However, if you own other (non Bushmaster) rifles specifically chambered for the .223 Remington, you should not use 5.56mm ammunition in them as it is considered by SAAMI (Small Arms and Ammunition Manufacturers Institute) to be an unsafe ammunition combination. (This 5.56mm/.223 Rem. information from Bushmaster Gunsmithing and the Winchester Law Enforcement Ammunition Website.)
  10. I don't decap before cleaning either. I've never had problems (would be high primers or duds?) When I started with my 650, I wrestled with this as well. In my rockchucker days I very carfully cleaned primer pockets (brush on a dremmel). Heck - range brass looked new when i got done with it. I also liked guns that were shiny wood and blued finish. Figured I'd just try it a few times and see. All that was about 75,000 rounds ago. Now my guns are matte black or stainless metal, plastic or metal grips, and they are usually kinda beat up and dirty 'cause I shoot them all the time. I have some 308 stuff that I absolutely babied. I did every step as perfect as I could (including cleaning pockets). I can't tell any diff between that and stuff that I cut a few corners on. Both shoot clover leaves at 100yds.
  11. Never seen this happen, but we shoot'em at a pretty godo pace, so there's not a lot of time to calculate. Also, we keep the scoresheets on the clipboard (shooter doesn't carry them around) Just too complicated. Requies someone to keep track of all this stuff. If you don't send it to HQ, the MD keeps track, along with all the other stuff... No way! one of the complaints about USPSA is the complex scoring and classification system (hit factors, major/minor) You gotta have a claculator to know how you did on a stage. Statistics and normal curves? 2/3 IDPA shoorters would probably tell you that statistics refer to a woman's body measurements and normal curves are on woman that's not to skinny, not to fat - normal. Heck, powerfactors confuse many people. Just a little too scientific and rigorous to fly in the real world. Remember those of us posting here are a self-selected group of techies. I think Sir Winston had it right (referring to Democracy) - something like: it is the worst system possible, except when compared with the others.
  12. Fo - let's get together and get the rules changed...
  13. +1 to Flex. Pointing this out is NOT being a Range Nazi. Now if the guy was an a_-hole about it, he's still not a Nazi, just rude, but right. Pointing the gun over the berm is very much a no-no. Always. But, you say, it isn't loaded. In addition to what Flex said (they are always loaded), when you seat the mag, the gun is for all purposes, loaded - you ever had a gun flip into battery unexpectedly when you slam home a mag? I have. Glocks do it a lot. Now you've got a hot weapon pointed into the sky. Nope. I believe a gun at slide lock, no ammo in a mag, laying on a table is perfectly safe, still don't want it pointed at me. Gun in someone's hand at slide lock and a guy getting ready to stuff a hot mag in it is NOT perfectly safe. I don't see any ignorance on the part of the SO. Ok, sorry to hammer you John, but there is one more point. If you've laid off for 15 years, you may be coming back into a heightend sense of safety. I don't know your age, but my dad (late 60's) and his dad, both military, have terrible safety practices - just wasn't the way they learned. The didn't wear safety glasses or ear protection either.
  14. I agree with shred and Dave - more of a "feel" situation, especially when I'm shooting 7's, 8's or 10's. Don't know if it weight or something else, but I usually know ehn the last round is in the gun. When I shoot more (i.e. Glock 17) I don't do so well knowing where the end is. Steve: A touch of Zen...
  15. Short answer is yes! I have a Kimber version and a Glock conversion as well. My club doesn't allow us to use 22s in the action pits (yeah, your're right) so I mostly use it at the standstill range. Still very helpful. I have very little problem ever. Be sure you use high velocity 22s, cycling can be an issue if you don't (put that's in the instructions). The only thing I don't like is that they are 10rd mags...
