My concern is the varying in starting load, as you can see from my OP hornady starting load is noslers Max! My lee and Sierra manuals don't list HP-38

Do your manuals show any info for W231? Same powder. Hornady 7th shows a start load of 5.9 with a OAL of 1.230. Nosler shows a OAL of 1.200 with their bullet, A shorter OAL generally means a lower powder charge. Also, Nosler shows a max velocity of 850fps, while Hornady shows 1000fps.
...and don't throw the Lyman manual away. It is a very good manual, I have found it not to vary any more than other sources. In magnum handgun loads, they tend to be a tad hotter than most, but this is one reason one should ALWAYS use more than one source before developing a load. I always try to use a least three sources of reference when trying a new combo. Anyone source that is excessively high or low gets thrown out. If more than one source shows similar data that's where I start, otherwise I average the data out from those that are close to each other. Has always worked for me.
