  1. I've always assumed the pressure cause/effect to be related to the percent fill for a given caliber/powder (and grains of course). A bullet needing to be loaded that short is probably stubby and likely shorter that the bullet profile tested at 1.13". Do that math in additional to working up a load.
  2. There's the rub with my approach. The "problem" I was looking for was function, primarily failure to feed and the gradual increase in felt recoil attribute to bad habits (support hand) and, alas, age.
  3. My wife and I shoot SC with our 9mm 1911 Springers. Normal springs 9 lb. recoil, 19 lb. main. This has always worked with our very light loads for at least 75K rounds through each gun, not that the recoil springs are original, but they have seen a very high round count. After a 6 month hiatus due to relocation to Idaho I've had a heck of a time recovering the sight picture for follow-up or next target shots, and I tried everything. I've always thought to change the recoil spring based on the gun not cycling (failure to feed). Out of frustration with my sight management I brought our two backup guns to the range, same springs and trigger, but very low mileage. These two unused guns shoot like 22s. I can only imagine that the weak recoil springs in the high mileage guns really alter the recoil impulse dramatically. I'll go on a regular spring change schedule, probably every 2 months would should be about 5K rounds. I assume most who run a 1911 do periodic spring replacement. I just feel incredibly dumb for having followed the "If it ain't broke don't fix it" philosophy.
  4. Been there done that. You can buy surveying whiskers on Amazon in at least 7 colors. they are more durable than you would think. As far as measuring I would just run a tape downrange and measure cross range for close enough. Having moved to Idaho my wife and I have lost our permanently-marked range so I'm putting together a series of tripod-mounted "plates" on which I can swing a red dot sight. I'll be downrange with a tape pegged underneath the tripod. I should be able to mark a stage in 10 minutes. Was going to use a laser tape measure at the tripod end instead of a red dot, but the tapes that work in bright sunlight at distance are expensive.
  5. Thanks all. I was certain the rules don't prohibit, but it is a start position where some ROs might not be able to see the gun at the start. This may turn out to be moot as my wife may find to a bit awkward to switch between her iron sight 1911 and her new Ruger 22/45 Lite. The grip angle on the Ruger is identical, but the sight axis is displaced quite a bit with a C-More. I'm getting an Allchin mount which will help.
  6. Title says it all. Low ready imprints poor muscle memory relative to self defense or center-fire pistol in general.
  7. Bullet Sense Issue: I've go well over 100K rounds (I don't keep track any more) through my 1050/Mark 7, all with a functional Bullet Sense. I recently moved to Idaho and had to reassemble things; surprise, everything worked, but I did notice that when I dialed in the sensor the laser was close to the edge of the mirror. After about 5K rounds in it's our new home out of the blue the sense function has stopped working. Laser works, reflection, while not crisp, covers the sensor, bullet sense is enabled, but the function simply isn't working. Anyone else experience something similar ? And, of course, I'll contact Mark 7.
  8. Not sure this would be the issue, but it's very standard practice to add a 45ACP case to the top of the primer push rod. I did so about 150K rounds ago, but I can't recall if that was just 'cause everyone said it was a good idea or because I had an issue.
  9. There are certain target locations that can be an issue depending on how gar behind the line the berms extend and the height of the berms. The stop plate in Five to Go comes to mind. Normally, this stop plate faces the shooter, but if the berms don't extend past the firing line you can get some pretty high velocity frags heading toward bystanders. To mitigate turn the stand CCW a bit. Fragments that have to travel over the berm generally have pretty modest velocity. Stating the obvious - hats and polycarbonate (or similar) eyewear which wraps around the side. Regular eyewear is an absolute no-go at a steel challenge match.
  10. Buy and inexpensive single-stage press and resize on that. Much faster than doing this sort of thing on a progressive.
  11. I did believe it to be a "real thing". The magnitude of the effect surprised me. Note to self, always sight in a new load. I switched to the slightly heavier bullet because I preferred the feel, but didn't both to shoot any paper.
  12. Went to the range with some old 124gr loads for my HK P2000 EDC and some of my very soft 135gr loads for my competition (SC) 9mm 1911. Range was 7 to 10 yards. Worked the HK a bit in preparation for an Enhanced CCW class (Idaho); just moved two months ago and hadn't touched a gun in 4 months. Switched to the 9mm and found I was grouping about 1" high. Hadn't brought that much of the usual 1911 ammo so tried the near-factory HK load and the groups were centered on the target. I repeated this "experiment three times and the POI of the 135gr load was consistently high. This is certainly not the ballistics; I expect what I'm seeing is the difference between a light/faster and heavier/slower bullet POI, but an inch at that short range seems extreme. The gun is on the heavy side, but at 73 y/o I don't have a gorilla grip. I've seen discussions noting differences between 147gr and 115/124, but I'm wondering if the degree of POI shift makes sense? FWIW the recoil of the HK round (124gr FP) is slightly greater, but still very slight.
  13. I bought one with my Mark 7 and had the same thought. A bench-mounted button with more positive contacts would be much better. I love my Mark 7, but found that a quick thumb press wouldn't always close the contacts. Once I got past the learning phase I no longer need the button.
  14. I capitulate! I mount a 2x4 to the wall backed up by t-nuts. Bolt the 2x4 to the bench, back the bench up to the wall, mark the 2x4 location, screw 2x4 into the studs and re-bolt bench to 2x4. Never had a problem going through 150K rounds. Just lazy.
