in the current issue of hand loader magazine, there is finally a real article about the 460 S&W . the test were run in 15 degree temp . while having a gun that weighs 76 ounces, burns 10 to 12 grains more of like powder to acheive like velocitys as a FA 454 casull . this was my thoughts when the 460 first came out! i have 3 FA 454 casulls a 6" a 71/2" and a 9" when performing load work and chrongraphing at the same time i have found that up to a point useing H110- 296-lil gun you gain about 50 fps per grain of powder up to a point then you can add 1 to 2 grains more powder with no velocity gain , i have run in to this in almost every case reguardless of bullet weight or pistol i used! i have gotten 1942 fps with the FA 240 jhp bullet in the 9 " a 7 1/2 with a ssk muzzel brake and 1926 fps in the 71/2 inch with 4 port magnaport with 38 gr 296 im sure you can make at least 2100 fps with a 200 gr bullet in a 454 casull which is possibly 100 fps less than the 460 S&W.
