Im using the 700 grain gas check hard cast bullet with 30 grains lil gun. My question is how long is the length going to be? I know its longer than the standard round, any advice?

You are wasting your time and money with those super heavy weights. They are not needed now and never will be. They are just a novelty item..maybe for bragging and that's about it...nothing a hunter would ever need for any size game. You are much better off using 350gr - 440gr hardcast depending on what you are hunting. I thought everyone was over this by now.

I have some 420 grain punch bullets i use for hunting. I bought a bunch of 700 grain bullets for fun and they are not to expensive.

I USE 25 GRAINS H110 ,CCI250, STARLINE BRASS, CRIMP TO FRONT GROOVE, I use this load as my bear gun when fishing here in alaska.oal is about 2.30, still room in cylinder

When I loaded some up for my 500 Mag, I used the following data. My over all length was 2.285. The recoil on these are not fun at all. I am with Woodrow on this. 440 gr. is all one will every need out of a 500 Mag.

500 S&W 700 gr Cast (RR) H110 25.0 gr. WLR 2.285 OAL


This was my light load.
500 S&W 700 gr Cast (RR) IMR4759 22.3 gr. WLR 2.285 OAL

This photo sums it up nicely:

I will point you to John Ross, who has worked extensively with the 500 Smith and numerous bullets, especially the heavyweights.

That was a good read. I gathered the super heavyweights are LESS potent than the mid range like 440-500gr AND harder on the hands...and a lot less accurate using the standard twist rate of rifling on factory revolvers. Very interesting.

Woodrow, the 700 gr. are a real handful. I got some just to try. It is true the accuracy is not as good with the heavier bullets, as with the lighter 440 gr. I found after shooting thousands of different bullets, the 400 to 440 were the most accurate in all my 500 Mags. I would never feel under gunned with a 500 Mag, and a 440 gr. bullet. I don't see a need for anything bigger than a 440 gr. bullet for the 500 Mag.

I've loaded em over 26 gn of lil gun. They dont shoot worth a damn. Wont stabilize properly.
