  1. The 38/357 extractor should work. Might need to run a 38 super chamber reamer in there, but maybe not.
  2. Not necessarily better, mostly cheaper. Power Custom, Apex, and TK Custom all have very high quality products.
  3. Check for a burr or sharp edge on the firing pin hole. Sometimes the rim can get hung up there. A small edge break with a chamfer tool or drill bit will eliminate any chance of that problem.
  4. If you go custom, get at least a 1 in 14. I like the 1 in 10 better. I think a 1 in 12 would be about the ideal twist rate, but don't know anyone making that twist. Alternately, you could get a 6" factory barrel shortened, but that might cost almost as much as custom without the benefit of the tighter twist.
  5. If they don't let you have a reshoot, threaten to start shooting hostages one at a time until they do...
  6. The 6.5 to 7 pound range is realistic with stock parts, except you will need a lighter rebound spring.
  7. The extended firing pins were origingally invented to make up for variations in primer seating depth, rim thickness, moon clip variations, endshake, and whatever other variations from perfect engineering drawings might arise. This was during a time when the factory pins were running a little on the short side, so you had to have a really heavy hammer blow to set off primers in the average gun. The original intent was to get a pin long enough to have a decent action under a variety of normal slight variations in gun and ammo. The shortest reliable pin length I've seen is .495, which is the longest factory pin I've measured, with most of them being from ..482 to .485. I prefer a pin in the .500 to .505 range. I like the Power Custom firing pins. If every gun was exactly to drawing specs and every ammo had flush seated primers (not .010 below flush), then we wouldn't need extended firing pins. In the real world, there are small variations in everything, so the extended pins are good insurance. Some gun and ammo combinations don't need an extended pin because they vary towards print dimensions. Some guns and ammo need an extended pin because they vary away from print dimensions.
  8. For any who may not be aware, Hogdon's line of Extreme powders are temperature insensitive. They will have the same velocity over a wide range of cold and hot. Lots of rifle and some pistol powders.
  9. Nice to see you back, Mike! Happy New Year.
  10. Use sandbags or a rest and then the 290 Loctite. It works very well.

    Revo holster

    I have a Hogue Power Speed holster adapter for revos that makes one holster work for all Smiths from 4" to 8-3/8". It takes a few seconds and no tools to change from one gun to another.

    Smooth out the mating internal parts. Weigh and record the hammer pull with the trigger pull gage and record the lightest setting that is 100%. Then find the lightest rebound spring that you like the trigger return of. Is it quick and positive enough? That is the lightest trigger on that gun that you will like. No 2 guns are exactly the same.
  13. Right! And coming up with a bunch more articles and photos would be the second issue, etc., etc. If anyone could do it, it would be BritinUSA!
  14. The extractors used to all be pinned. At that time, the stem of the extractor had a groove with a keyway running lengthwise and a corresponding key in the cylinder. The pins were never quite in the same place from one to the other, so there was a good bit of work involved with fitting a new extractor. The new style has a D shaped stem with a D shaped hole in the cylinder. Additionally, the outside is milled in a square pattern which accurately orients the extractor to the cylinder, to replace the pins. With the new style, the extractors are easily interchangeable, making production and any subsequent repairs much easier.
