This is my dilema. I'm loading 30/30 rounds using a 170 grain jacketed round nose bullet (Hornady), Win 748 and the 1.9 (Listed as 29.0 grains) dipper which is recomended by Lee. In the Lee book it Reads: Win 748 Start grains 29.7 , Lee dipper 1.9 , 2007 velocity. Never exceed 32.0 grains , 2145 velocity. In the Hornady book it list 33.1 grains = 1900 FPS, 34.8 grains = 2000 FPS, 36.5 grains = 2100 FPS. 36.5 grains is the max listed by Hornady.
Here is what I would like to know:
1) Why is the max load in the Lee book listed as 32.0 grains max and Hornady says it's 36.5?
2) The Lee 2.2 dipper is listed as 33.6 grains. According to the Hornady data I could bump it up from the 1.9 (29.0 gr) dipper to the 2.2 (33.6 gr) and still be within the safe limits, right?
Before anyone mentions it, I know I really need a scale; it's on my next thing on my list to buy, I'm just trying to work with what I got. Also I'm not trying to really find the max load I can use (yet) I just noticed the data was way off between the two and want to know why.
