I dont cast yet, no room to do so, and i spent all my money on powder and primers.. so the supply of store bought lead will have to do for some time.
My bullet to try is the matts HP version of Lyman 358429
I know the official use of the bullet is to load it in a 38 special case, 12-13 grains of 2400, and crimp in the groove.
For magnum use I am supposed "crimp over the front band".
I am slightly wary of this loading data as previous matts bullets in 158 grain swc lead heavily with standard powder charges, and I have no clear photo showing the proper crimp in a magnum case. As i bought these for dog/coyote I need to have hope of expansion.
If used in 357 magnum cases, is it normal to try to put lube in the "crimp groove"
