So, What's up with this, went to play around with loading for small bullets and the numbers are Way different between manuals,
Speer Manual #14 for 100gr HP, 270WSM
IMR 4350 Start Charge - 66.0 Max Charge 70.0
Hornady Manual #7 for 100gr SP
IMR 4350 Start Charge - 58.3,60.1, 61.8, 63.6, 65.3, and Max Charge 67.0
Man, that seems wierd that Speer's start is one grain short of Hornady's Max charge using same powder for same weight bullet ?
Just noticing, using the Speer bullet but checking other manuals Speer's numbers are way higher, makes a guy a bit nervous?
Lyman's 49th #'s for a 110 gr bullet are similar to Hornady
IMR 4350 start chg - 62.5 and max -66.0
Any advice on this?, I loaded twenty using the Speer numbers as I was using their bullet but haven't fired them yet......
