    I have liked the results I got with WSF with my 9mm so today I decided to give it a go with the 40. I shot 10 rounds of 180 gr with G35. No crono today. All shot freehand. At 25 feet.

    4.7 gr Fully function gun. 3.5 group feels good best three 2.25 inch.
    5.0 gr Fully function gun. 3.0 group favorite group best three 1.1 inch
    5.5 gr Fully function gun. 2.5 group tighter but more felt recoil best three touching.
    5.9 gr. Fully function gun. 2.5 group wow she sure does bark best three 1.5 inch.
    Looks like somewhere around 5.5 is going to be my sweet spot.

    Thanks for sharing, I think WSF is a pretty decent and flexible powder. Were your 180 gr, jacketed, plated or lead?

    Is the 49 SW a new caliber I slept through the development of? :dunno:

    Like when you slept through the invention of smokeless powders?

    WSF is the go to powder for range level 9mm, 40, 10mm, and 45 ACP. It's also a hoot for the .32 H&R Mag if you are brave to go there.

    Yep, my fav for the 40 as well. WIth a 175grLFP o/ 6gr I get just under 1000fps & sub 1 1/2" groups @ 15yds (USP or 4006). Same load w/ the 175grSTHP goes right around 950fps, sim accuracy but don't expect them to expand @ that low vel, they won't.

    Following Fred's advice I just tried WSF in my two 49 caliber plastic guns this week. :supergrin:
    Haven't worked up anything for either gun, started with 4.8 under a 175gn cast TC.

    My groups with 180 grain bullets (Zero JHP) & WSF seemed to reach their best at about 5.3 grains which is very pleasant to shoot. Heavier charges shot well also but not perceptably better although recoil increases. The same was true of 165 grain (also Zero JHP's) at 5.5 grains of WSF.

    According to my book

    5 gr 860 fps 22900 psi 155pf
    5.6 gr 950 fps 28300 psi 171pf
    6.2 gr 1040 fps 33200 psi 187pf

    So I knew all the charges were fine I just wanted to try several different spots in the power curve and get it closer to were I want to test. Looking at my results I am going to break 5.0 to 5.5 into smaller bites and retest for accuracy.

    I am using Rainier 180 copper plating.

    I will certianly give that load a go.

    WSF is a very good "all-around" powder in .40 S&W. I also shoot a G-35 and most of my loads are well below factory velocities. I have no interest in mimicking the factory specs and generally speaking, when the gun runs well and the groups are there with no improvement shown loading any hotter, I call it "good". Anywhere from 5.3 to 5.8 should do very well.

    Yep, it was specifically invented for the California crowd and is designed to get around the 50 cal ban... ;)
