Just a quick reply about Oregon trail load manual. It is still available. Just purchased it with an order of .38 cal 158 grain lrn laser cast bullets.All of their recipie loads for the 38 specials were developed using a 686 with 6" barrel. Loaded up 50 rounds using their data for unique and fired them yesterday in my 686 6" (brand new only the second time it was fired.). Smokey load, lots of carbon on the outside of the cylinder, light surface lead deposit (almost like dust)inside the bore and decent accuracy. Cleaned up nicely. Will try some other 38 special loads this weekend using 231. The book was worth the money ($39.00)
