Would def like to find out more info about these. If I am normally reloading, I use .355 diameter. do you think I would use the same with this bullet as well?
It depends on what your normally loading? If you load jacketed bullets .355 is probably OK. If your loading lead bullets, I would up the size to .357 to help seal off the hot gasses during ignition and reduce leading. You'll need to work up new loads if changing bullet size.
The real answer is to slug your barrel and precisely measure the slug to determine the right size bullet. Once you have an accurate slug diameter then you can order the right size bullet. Generally for lead/coated lead you want a .001-.002 oversized bullet. Meaning if you slug your barrel and it measures .3555 inches, you would do well to get a .357 bullet. If it slugs at .3545, you may choose a .356 sized bullet.
In order to measure precisely you need a micrometer, so if that isn't a tool you own, you you can just use the rule of thumb .355 for jacketed and at least .356 for lead (I always order .357 but my SP01 slugs at just under .356).
