I shoot the 180 Grain "Classic" load in my 40. I didn't own a 40, but finally broke down and had to get one.
The reason I use it, yes there is better stuff out there but the "Classic" is still pretty darn good IMO, is because I can find it easily. In my 9mm I load the 115 Grain +P+ load. That's the "hot" load of the 9BP "Classic" load, with the Hi-Shok bullet.
Technology changes but I tend to be "old fashioned". If the Hi-Shok bullet worked a few years ago, I see no reason to think it won't work now. Yes, we could spend all our time trying to find the "best" bullet, but after a certain point I think it becomes foolish. First off, any new to me ammo has to be tested with a minimum of 200 malfunction free rounds in the gun I'm going to carry it in. Since I have to buy my own ammo for off duty carry with a personal gun, that gets exspensive real fast.
The "Classic" line may not be the "newest and best" but I can afford it. Heck, I still load the Remington 125 Grain SJHP in my .357 Magnums. That's the load that gave the .357 Magnum it's moniker as the "King of the Street". Yes, there are lighter recoiling loads that probably work just as well, but I KNOW the Remington load I use will work if I do my part.
The good thing about using some older bullet lines is that it's usually cheaper than the "newest and greatest". That means I can buy more to practice with, because I still have to do my part and put the bullets where they need to go.
