Been reloading pistol for a few years now and in 38 used DEWC and "the" recipe of 2.7gr bullseye.
Got new guns, new sport (CAS) and new bullets (158 RNFP) for use in a rifle.
So I figure it's a good time to work up new loads specific to what i"m doing. Also read an article (posted in another thread here) about small volume loads in large volume cases and how position of the powder in the case at ignition can have a large effect on pressure and FPS.
Figured I check my 4 books and alliant's site to get 'all' the data...and ****, is it really science or black magic when it comes to load data?
Some books' starting loads are more than other books max loads...one book has a max load that is well above another's +P load...
The 148 WC data is fairly close - 2.5 to 3.1 with one going to 3.7(!).
The 158 is the tough one..2.6 to 3.6 in one book and 3.8 to 4.2 in another...Alliant says 3.5 (I assume max as they only list one figure).
Now to decide what to actually make up for test loads...
