I was going through some of my 308 win ammo today and came across some loads that I loaded to mimic Fed Gold Medal Match with 168gr Sierra Matchkings hpbt. I had two loads, one with 46gr of CFE223 and one with 40gr of IMR 3031. I know I used my Hornady data book or the Hodgdon website to get the data.
When I checked the Hornady book, for 168gr bullets it said a max of 47.2gr of CFE223. I decided to recheck the Hodgdon data center and specially for the SMK 168gr it said CFE223 was good until 49gr.
That seems like a huge disparity... I know Hornady data is more conservative, but still!
I decided to pull the bullets and start lower.
I was trying to match velocity of the Fed GMM. But now that I think of it, that is an unsafe way to load...
Those of you who load 168gr SMK, do you load with 3031 or CFE223? If so, what are your go to loads for 308 win? For your rifles of course. I'm not looking to use anyone else's data, I'm just curious if I pulled my bullets unnecessarily.
