Robert DuncanBlue Dot loads for .357
I have some 158 gr cast bullets, BNH 12, that I would like to load to about 1100-1150 fps to keep leading down. I have Blue Dot and 2400 powder and wonder if anyone has some good loads in this power range. This is for a Colt Trooper with 4 inch barrel. The published loads I find are well past this range and would probably lead badly.
Thanks.
I stopped using it years ago,too much muzzle flash....2400 works great

LuckyduckerMy go-to load for 357Mag is 10 grains of BlueDot with a 158 grain cast bullet, but I have never ran any over a chonograph. I consider this a mid range load compared to loading 2400 or H110. I think .404 should stop shooting at night if he doesn't like muzzle flash! I have never noticed muzzle flash from my Taurus 66 with this powder.

craigsterI love the flash of powder in the morning. Or evening.

SlamFireI gave up on Blue Dot because it leads with cast bullets. Blue Dot only works well in full bore magnum loads and jacketed bullets.
The day I tested Blue Dot in my 357, I got leading at velocities I did not get leading with AA#9 and 2400.

GLShooterI pretty much stick with 2400 on my lead bullets. I have reserved the Blue Dot for my jacketed stuff.
The 10 grain level gives me good velocity and I find leading to be minimal.

Robert DuncanGreg, are you saying that 10 gr of 2400 is your load with 158 gr cast bullets (plain base)? I want to avoid leading as much as possible and am not interested in true magnum velocities. When I go for that, I will stay with jacketed. Thanks.

GLShooterThat is correct. I am using 10 grains of 2400 under a hard cast 158 grain RNL bullet. Shot out of a S&W 586 6".
Velocity is in the neighborhood of 1000 fps.
