Love mine...... trigger even better after "fix" Welcome to try mine.... -
Fixed trigger group is much better than the previous version. Cleaner break and better let off and hardly any after travel. The upgrade is a definite plus. Find the grip size and color you like and you are set. Different slide and frame same trigger. Nice solution. Get a full and a compact kit and away you go. Of course we are neutered at 10 so there is a consideration. All in all. me like, big time. It does not shoot like a Crock 17,19, 22. -
The funny thing is that when you start fishing from the shore, you cast toward the middle of the lake and wish you had a boat to get there. Then you get a boat and spend all your time cast toward the shore. Go figure. -
Based on what you're saying your film was severely underexposed. The negatives were pretty much clear weren't they? If overexposed they would be very dark. If you were shooting f2.8 @ 1/100 with 200 iso in a darkened room that was underexposed. Most people don't realize the difference in the intensity of light. Bright sunlight is thousands of times brighter than average room light. Exposure for a brightly lit gym with 1600 iso would be f2.8-f4 at 1/250. A well lit office (much brighter than your average home lighting) would be f2.8-4 @ 1/30 with 400 iso. I did a lot of available light photography. Theater, art, and surveillance photography. I used 1600 for color and 1600, 3200, or 6400 for black and white. Most times with b&w negative film it was push processed. For example 400 iso shot at 1600 by developing it longer. Some color slide films were capable of being push processed but never knew anyone really successfully pushing color negative film. When you push process b&w film what you do is expand the tonal range in the negative. You can also shoot b&w at the rated iso and extend or shorten developing time to expand or contract the tonal range. That's getting into Ansel Adams and Minor White stuff that Adams popularized as the "Zone System of Exposure". Really way beyond what we're talking here. I did a bit of work with photographic chemistry. All film has a certain degree of exposure latitude. It varies with different types of film. That's a range of over and under exposure where you good still get a decent print. 2 stops either way is very good. Slide films has much more narrow exposure latitude. Using 200 speed film in a brightly lit office would call for f2 to F2.8 @ 1/30. Not knowing how much light your "darkened room" had, I would guess your exposure should have been 1/4 or 1/2 second with iso 200. You really should be using a tripod. You can't handhold at that speed without camera shake. If you're shooting anything that doesn't stay still you're going to get subject movement. Try using faster film if you want to shoot low light. If you want to try black and white try Ilford XP2 film with a iso speed of 400. It is black and white film designed to be processed in C41 chemistry the same as color negative film. It can't be printed on color or black and white paper. It normally comes out sepia toned when printed on color paper but if the printer knows what they're doing they can adjust the filter pack in the enlarger to make true black and white. Do yourself a favor and when you get color negative film processed pay the few bucks extra and have them cut a cd. Much easier to knock out a few extra small prints that way.

OK how do I put this? 6.5 caliber is not new. The Swedes knew the ballistic advantage of the 6.5 while we were still screwing around with developing the '06. The 6.5CM was just a revisit and tweek to take advantage of a competition course of fire on the range by shooters. The 50BMG was developed as an anti-aircraft round for WW1. The 300 Winnie has only been around since 1963 and is a necked down version of the 338 Winmag and 375 Holland and Holland. It kind of was an after thought so Winchester could use their model 70 action with a belted case. 380ACP was Browning answer to a small pocket gun where weight reduction and size was key. The round is a blow back design so there is no barrel lug or lock up just the mass of the slide and bolt control recoil. Being rimless streamlined its function for SA firing. Luger and his 9mm was an improvement on the first rimless cartridge the Borchardt. Germany wanted a bigger caliber, and his thought was to include the cartridges within the grip of the pistol improving function. The 223 Remington was another rework of the 222 Remington from 1950. With the request of a new rifle for the Army this round was shoehorned and tweeked again into an idea the a smaller round with specifically defined capabilities was a better fit than the previous 7.62 caliber. The 45ACP, well a sort of SA answer to the 45 Colt. The original design was in .41 caliber but the Army wanted something equal to the 45 Colt in diameter, so the 45ACP was the answer. Oh, and that 40 Short and Weak, was the redesign when the 10MM proved to much for small handed FBI agents to use accurately. So it seems todays' popular cartridges are an evolution from a different beginning. Funny how that happens.
