campro 180gr with 4.6 grains of titegroup is a nice load that makes IPSC major and cycles perfectly for me.
Last 20,000 round were of this
cheers
Campro 180 gr with 5.9 gr of CFE-Pistol will do fine also.
Noone mentioned OAL which plays a big factor in reloading. I reload 180gr at 1.18 OAL and no way any of the loads mentioned above will make major power factor with this OAL. What gun are you shooting and what OAL are you loading? Than figure out the charge. Mine is 5gr of TG and it is right on the border of major with 1.18 OAL!
Every double charged blown-up 40 to come by my shop was done with titegroup.
It may be cheap and work well, but it is apparently easy to double charge and not notice.
Load carefully.
Highly recommend the lee undersized 40 sizing die. Makes for an great, strong crimp on plated bullets without breaking the plating.
Skip the 180 grain bullets. The recoil impulse is almost the same as 45acp.
Where 40 S&W really shines are with light bullets. Campro makes 155 grain & 165 grain bullets. Like most auto pistol calibers, 40S&W gives excellent performance & accuracy with fast burning powders. Small charges of fast burning powders like WW231, RedDot, Clays, WST, 700X, Bullseye......
