I have been loading for a very long time, but within the last 6 years I have converted over to plated bullets. Our indoor range stopped allowing lead because they said it was very hard and expensive on the air filters. So it was either go to no lead or raise the price to replace the filters more often. So within the last 6 years I have been using berry's 180gr plated bullet in 40S&W.
The manuals I have and used in developing loads for testing are
Hornady #3, #7, #8 ---- #3 is so old it does not have 40S&W load data
Hodgdon paperback 2008,2009,2010,2011
lyman 48
lyman 49
Sierra edition 5
Speer 11, 12, 14 for some reason the 40 S&W loads here are HOT, probably has to do with their components and ensuring proper bullet expansion as well as their testing equipment. These loads start out where Hornady and Sierra max's out.
I have found for 40S&W Hornady and Sierra seems to have the best loads.
Hornady for 180gr and HS6 is 6.2-7.2gr
Sierra Edition 5 for 180gr and HS6 is 6.2-7.6
I have found for 180gr Berry 40S&W and HS6 6.6-6.8 seems to be the ideal load. HS6 is slower burning than the likes of W231 which I was using before, it is less snappy and shoots to point of aim out to 25 yards in my 40S&W platforms. Anything lower than 6.6gr of HS6 shoots soft but leaves a lot of unburnt powder behind. Over 6.8gr of HS6 shoots very well and accurate but the snappy recoil the 40S&W is known for starts to return. Though I only carry factory ammo for self defense I keep 50 rounds of reloads around where I try to replicate factory ammo just in case.
Federal Hydro Shock JHP says it produces 1000fps
7.1gr of HS6 seems to replicate this load over the chrono producing 1000 fps with berry's 180gr hollow point.
So Southersorrow and I have come to the same conclusion, 6.6-6.8 is the bulk of my reloads and what goes with me to the range.
This load will cycle my Beretta 90-two, Sig 226 and Glock 22 with Lone Wolf Barrel.
40S&W is known for blowing up weapons and causing injuries so safety should be your primary concern when reloading it. Please do not read any of this ammo and run off to your reloading bench to start reloading. Crack open a reputable reloading manual and check the loads then start at the very lowest point your reloading manual dictates.
