Looks for Target

Looks for Target (4/11)

  1. Scientists have long assumed that the eyes undergo temporary blindness as they shift focal points, but a new study from Science Advances (https://advances.sciencemag.org/) reveals that your eyes absorb key visual information during this time. Link to the paper: https://fcld.ly/384wkw9 Science Advances is a top tier peer-reviewed scientific journal.
  2. I had a blood test during a time when I was shooting a lot, both indoors and outdoors. I was not not reloading or handling spent brass, though. Lead levels were undetectable. My habits were: never touch face or food when shooting, wash hands and face immediately after shooting, and take a cool shower and change clothes when I arrive at home. So, it is certainly possible to eliminate lead exposure if you are just a shooter. Reloading is a different issue.
  3. No, recoil is momentum. No, supersonic bullets create a supersonic shock wave, subsonics don't do that. I agree though, generally the total energy (i.e. powder) is a better measure of "felt recoil".
  4. "Pick any caliber, and bullet weights to compare, and compute " That is exactly what i did in the OP
  5. In the OP I gave exact numbers from the Speer lawman line and compared 115 to 147 grain. The heavier Speer has more physical recoil but does feel "softer". I think this is all psychological: shooters reacting to supersonic blast and "feel" it is recoiling more.
  6. so, do you agree with my assessment that the so called "perceived recoil" is actually supersonic blast of the lighter 9mm bullets?
  7. When I was a beginner and shooting only factory ammo, I was told to stay away from lighter bullet weights like 115gr, and use 147gr because heavier rounds would recoil lighter. My experience confirmed this: 147gr rounds felt better and easier to control. Physics, however, tells us that recoil is momentum, and a heavier bullet at the same speed would generate larger recoil. So I compared momentum of a typical factory ammo like Speer lawman, at 115 and 147 grains. Based on factory specs, the momentum of the 147gr is actually larger than the 115gr, but by only about 5%. I do not think anybody can notice this difference in their hand, but even if they do, the heavier bullet should recoil more. This is contrary to what people feel. What I believe happens is that because the 115 grain bullet is actually supersonic, it creates blast that makes it feel more "snappy" vs. 147 grain is subsonic and doesnt create the same shock wave and the perceived snappiness.
  8. I twice had dead triggers with p320 line pistols; one time due to the tiny little springs under the sear breaking or coming loose, the other time the striker "hook" that engages the sear completely shearing off....i have several sigs and like them but the p320 line is not the most reliable pistols out there
  9. Once I compared my accuracy in bullseye shooting when target focused vs. front sight focused. I did not see much of a difference in 25 meter 5 shot groups. Perhaps front sight focus is a bit more accurate, but I think the difference would be negligible for action shooting. I think you can be 100% target focussed, with fuzzy front and rear sights, and still get your hits, provided that you are aware what is happening to the sights as you pull the trigger.
  10. At those distances you can pretty much point it and press the trigger, or use the window of the dot as a reference, and you will hit. I still struggle from time to time finding the dot when I am at awkward positions, but it is never a full second delay. When I lose the dot it is always high, so it just requires a quick downward adjustment.
  11. Same here. I am a dot shooter in competition but have seen many dots that fail and broke so I prefer irons for serious use, for now. When they become very robust and easier to install (and when my eye sight deteriorates), I will switch.
  12. Same here. I think the dot is better and easier for a beginner, for intermediate shooter, and for an advanced shooter. But, it is particularly better/preferable for a beginner. Which is exactly the opposite of what he says.

    X5 trigger work

    GrayGuns trigger is excellent. Installing it yourself is tricky, but doable. There used to be good videos on how to install, which would save you a lot of headache.

    Open vs CO

    comp? single action trigger? open holsters? non-moving optic?
