405 in 460 S&W Mag.

[161]

Anybody sized a 405 Lee down to .452 for the 460. I made a dumby rnd last night.It will chamber In the big Smith revolver. But I wounder about the twist being fast enough for that heavy boolit. I don't know what the S&W has for a twist.

the twist is a gain twist style and winds up to a 1-20. I have an old NEI mold that drops a whww slug at 420grains with gascheck attached. Coal winds up being 2.3 crimped in groove. Used hodgdon data for a 390g for starting point idea. Use IMR-4198 to run it 1450fps. Great accuracy out to 250yds. Havent had chance to try longer ranges

I have one here that belongs to a friend. Are there any 2400 loads for the 405? I found some data for 300 gr.

Went out today, could only get 70 yards and shot off the hood of the truck with sand bags. The first picture is of a 405 Lee paper patch .sized .452 8 shots. Second is 4 factory that the owner of the gun sent home with me. They were a pointed HP in start line brass. He said he didn't know who's or what the are. I'm not a great magnum shooter. Largest until now is the 44 mag. The gun is a Smith 460 with a cheap red dot. Looks like to me my reloads shoot about as good as factory. Except not near as fast. The shells he gave me ran 2250 FPS, mine are 1200 fps. Paper patch held up. Not the best shooting but the conditions weren't the best. I think a person could make this combination work with some time and effort. The 460 is made to shoot light boolits fast. Not what I'm trying to do with a 405 grain
