I think in this cal. (460 S&W) the 340 grain WFGC cast bullet that I cast will be about the perfect weight for a cast slug one would shoot, I also think that heat treated wheel weight alloy will perform perfectly out of my custom 16" mgm barrel w/Reeder brake, and work better than jacket's for BIG GAME!! I think I am going to go with either AA5744 or AA1680, I want to get around 1900 FPS, I am wanting to know if anyone has ever tried AA1680 powder, I know as far as velocity 1900 to 2000 is doable with a closed breech and 16" tube it should be no problemo!! Any hands on for the 1680 would be apreciated!! I know 296, 2400, AA#9, and lil'gun will work, but I have about 4lbs. of 1680 and this would be my hunting load so it would last forever and is about in the perfect heat range for my wants!! This will be my first season with the encore 460, and would be great to go with my 454 SRH that I would reserve for very thick brush use or the last 2 or 3 day's of the gun season as we do a few drives, when they begin to hold tight! or hog hunt's, or any where under 100 yard shots are needed, or have a possible need for more than ONE SHOT! the rest of our Ohio deer season,and any other deer, elk, moose, and bear hunting the encore with this cast slug or the 300 grn. SST, will be my CHOICE WEAPON!! It will take any of the mentioned game out to as far as 250 yards, which is as far as I feel confident, and have enough penetration to drop them! So please let me know if anyone can give some info on the AA1680!! THANK'S and GOOD SHOOT'N
