when reloading for the 357 sm, would it be advisable to have bullet length as long as possible (as close to the end of the cyl.)? knowing that bullets for the supermag will not work in a ruger but 357 max. will work in either would indicate longer cart. length would be better for accuracy. if this is the case, what is the best overall cart. length?...just curious

I'm no SM loading expert, but... Loading to OAL for a revolver is much different than a rifle. With a revolver you still have to deal with B/C gap and escaping gasses. You also have to be careful with the cylinder "choke" or restriction at the face of the cylinder--Too long and they will not chamber fully.
You also have a limited amount of seating depth to work with--gotta have them deep enough to get some grip on them and crimp fully if necessary.
Bottom line is you need to experiment and see what works best in your gun... Sorry i couldn't be more help.

When it comes to revolvers, the crimp groove on whatever bullet is being used is what gives the length.

What if there is no crimp groove 
.... Crimp groove is just that--if you decide to crimp you have an option to secure the crimp better.
Somewhere I have an ancient CH cannelure tool--allows me to roll a cannelure (crimp groove) into any bullet I want.

On the OAL subject, I load mine to 1.98". This is with a 180gr Speer "TMJ" bullet, crimped on the cannelure.

Here's a video I found online of the CH tool… Here's using it on home-made bullets, but you can run it on any bullet.

I find it best to run the bullet as far out as possible and still get a good crimp (taper or roll). If you can reduce the distance the bullet travels in the throat, generally you have better accuracy. But, like Shoot said, you have to experiment- that's the fun of handloading and the difference compared to reloading.

Thats a good video on crimping. If you don't crimp I would look at the other cartridges after you shoot a round to check them. Some times with the recoil the bullets can work their way outward somewhat. I like crimping the SM.
