Sees Sights (6/11)

  1. I've never bought a new CZ, they have all been used (5), but I did buy a couple of Tanfo's new. Back to CZ, my Shadow 01, I never did get a set of sights that could be adjusted to POI to POA, close but no Cigar. Close enough to shoot production. Last year I decided to throw a DOT on it. Due to "political" factors I had new loads to test. My most accurate STI open gun is a tack driver, it connects all the holes at 25 yards with ease. Next up the 12 yr old Shadow 01, with its new dot. Ooh crap it is out shooting the STI. All shots fired from a bench rest. Then comes the real test, free style, same 25 yards, STI open nice group about 2" for 5 shots, next up the CZ, oops my FU is weak on this one, about 4". Not the gun the Indian. The steel test, like a steel challenge stage, on the timer. Not believing it but I'm faster with the CZ, the timer don't lie. On rifle grouping is pure science and discovery just a couple tenths of a grain makes all the difference in the world. In pistol the POI can move 4" at 25 yards just changing to a different powder (major power factor 9 mm), not so much with minor. Test the gun and not the Indian, do some shooting on a bench rest. Nothing wreaks havoc on pistol accuracy like a loose barrel bushing, then barrel lock up. I had a gun that the slide was so loose on it, it rattled when you shook it, but it was still very accurate with good barrel lockup and a tight bushing. When I shoot a strange gun I'm more accurate because I take more time on each shot, the psychology factor.
  2. I've only loaded a few 100,000 rounds, but I've never counted the cases. I keep Brass in a 3# coffee can, I pour in a half can at a time. When it starts to get low, and you can hear this, I pour in more. The amount of brass is a level that is @1 1/2 inches below the clutch. When you let the amount of brass run low you will encounter more anomalies, up side down cases, and the dreaded brass rain. I tighten the clutch as needed. When I pour in brass, I give it a shot of one shot, this keeps the reloading smooth and easy. I clean the case feed when its dirty.
  3. When I started shooting I would by 40 cal 250 rd boxes of ammo for $17.00 that is cheaper than primers today, granted that was two Dem presidents ago. I'm going wait a little longer to see if the price drops.
  4. If you have Federal Primers (SP) you can run a 10# spring, I've done that with 100% reliable ignition in WARM WEATHER. When the ambient temp dropped to about 40, things got weird. I started to get delayed ignition, I would pull the trigger, and it was like a second before the bang. It probably wasn't a whole second but it seemed like it, the first time it happened I was about to reach up and grab the slide when it went off. This continued thru the match. The next day it warmed up and it was all good, but I swapped in the next heavier spring an 11# anyway. I now use whatever primer I can get, and this led to inconsistent ignition, shooting a match I had a few failures. All of those failures were CCI primers, all the WInchesters went off. Some were rifle primers, and the ones with no dent at all were Magtech Rifle, they have a D on them. The good thing was it was steel challenge and it didn't spoil my match, just a few runs. I just got the calibration kit and changed out the 11# for a 13#. Upping the spring did not significantly change the single action pull, but since I have the short disconnect in the gun that makes the double action pull much shorter it did add a couple pounds to that pull. The shorter pull works for me, but you might like the long easy pull better, depends.
  5. LOL AA7 When I went from 10gr to 10.5 grains it tamed the beast. That was 38SC with a 124gr 11.2 gr for a 115. I've shot it in 9 maj with 10gr and it felt good.
  6. There is a point where friction and inertia meet, and when this happens the next round does not make it to the chamber. A 7# may cause the gun to stop feeding. Everyone has to try holes at least once. If it doesn't work out just replace the barrel and try a different comp. If your split is improved by .01 or even .02 this could add up to a full 2 seconds in a match.
  7. If I were shooting at running pigs I'd go for an EOTech or a HoloSun 2 moa. If however you might just want to shoot more conventional game, and I do recall a friend and I bugle up a Sika, he had that Bushnell and he couldn't make him out, I handed him my rifle with a Simmons 44 mag, and he said dam the sun came up and he could make the shot. You need a good pair of binoculars, those little rascals will sneak right up on you so close you can't see them without binoculars. A 3x9 or 3x10 is probably a handicap at 150 yards a good 1x4 with @50 mm would give you a good field of view, stay on 1 till you have a target over 200 yards. No scope will help if you don't know your zero and where it hits at different ranges.
  8. The recoil in stock trim was not conducive to fast shooting, IMHO. There was too much bounce, if it had shot as well as a Marlin Camp 9, that would have been good, but nope it didn't. This specific gun may not be representative of other blow back AR's, having purchased it used, not sure the prior owner didn't muck it up, but he said it was stock, he also said it ran and it did not. The ammo I was shooting could also be a factor, since it only feeds Round Nose reliably, I was using up the Ammo I loaded for Steel in a Glock Open gun, probably about 140pf. Have another 3# coffee can full to shoot up.
  9. I've got 5 of them so I'm gonna say I like them best, if I could I'd put one on my CZ Shadow.
  10. Engineering 101 duct tape or WD 40, I'll go with if it isn't broke don't fix it, or if brute force isn't work you just are not using enough. That load sounds a little rodent methane to me, I'd add a couple tenths and see if it resolves the problem, max load is 4.4gr.
  11. Most of the shooters I see are running stages without reloads, they have 55 round mags, but since I only have 27rd mags that run 100%, I'll be reloading, and I am going to practice your techniques. Thanks for the video.
  12. TexasTactical.org puts on a couple of IDPA matches every month in Bulverde. You could probably make a weekend out of it with IDPA on Saturday and Steel Challenge or Sunday, or USPSA.
  13. From the draw is just one aspect, as is following a reload, add to that you need to practice every common position, like leaning around a wall, crouching in a window, on the move and on and on. The preponderance of evidence clearly shows as you watch shooters struggle to find their CO dot match after match. My own experience making that transition from limited to Open, was within a week I thought I was ready, within a month I knew I wasn't. If you have even one hesitation in a match caused by the dot, well you have not mastered it yet.
  14. Those are all good valid points. I think the myth is that you are going to pick up a gun with a dot and magically be good with it in a couple of hours of practice, oops not going the happen. If one does a lot of dry fire from lots of odd positions and does reload practice I think you could get good in a few months. Just like guitar playing it is muscle memory and that is the same way you build your index.
  15. If you asked me how to find the dot, I'd say look at the target! Exactly your focus needs to be the target then bring the gun/dot into the filed of view. In steel challenge your eyes go to the next steel first as you transition. Tracking the dot only slows you down.
