Load Question

I recieved my equipment and set it up for 38spl. I have two manuals on hand, Modern Reloding 2nd edition and Lyman Reloading Handbook 49th edition. I purchased 158grn swc, Universal powder and remington primers. The Lee Manual list a 158grn lead bullet. The Lyman manual list a 158grn Linotype, I don't know what that means.
The recipe for these two are very different. I tried the Lee recipe as follows, 158gr. swc, 3.7grains of universal, and an oal of 1.475. I loaded two cases and put them in my 586 and stepped out on the patio and fired them, I had taken a couple factory rounds out as well.I couldn't tell any real difference. Does this sound like a decent target load?

Now that I got my feet wet I have more questions than ever, however I did learn that it takes some feel when seating and crimping the bullet. I was soon able to tell when I would over do it and seat it to deep and over crimp. An interesting thing is the over crimped rounds will not fit any S&W revolvers but go right in Charter arms undercover.

Another confusing thing for me is in the Lyman manual, it states, "bullet #358429 closely duplicates the factory 158 grain semi-wadcutter. This is the Elmer Keith design bullet and makes an excellent choice for hunting." When I look that number up it list it as 170 gr. linotype and is very similiar to the recipe I used from the lee manual but I don't understand the contradiction in weight. Thanks for any input. Dave
