Using WW for my .500 S&W loads?

[21Glock]

I have just about used up my supply of linotype mixed bullets for my .500 S&W Mag. I have cast them and water dropped them. 440gr. LEE FNGC bullets.
Then, I've sized and lubed them with White Label X-lox 2500 on my RCBS LAMII and then seated a gas check. No leading in these loads pushed to 1100-1200fps + with my various loads of Blue Dot and AA# 9. Certainly, not the top end on these loads.

Could I save a little on not getting more linotype and just use my supply of wheel weights when I cast up my next batch for my .500 since this is a high speed lube used for cast rifle rounds, along with using gas checks?

Anything beyond this fps and I think I will go back to linotype or jacketed bullets.

I cast the same boolit out of WW. I don't get any leading. I have pushed them faster than 1200fps. Not much faster though. For awhile all I had was WWs. One %#@& of a gun. I have a Handi Rifle in 500 S&W mag also.

I use wheel weight alloy and gas checks up to 1600 fps. in my .454 Casulls with no leading and excellent accuracy. I can't see where the 500 S&W would be any different.

Thanks for replies. I'll use your advice and try it out.
