So I have some magnum powders I hardly use anymore: Staball hd, V560, h4831

When I finish up the last of my h380 what would I lose besides velocity if I just switched to the slow powders in an 22-250 under a 55vmax.

It’s a slow twist tikka that shoots 55gr bullets okay and keyholes 69 gr bullets so it’s not ever going to shoot heavies without another barrel. It’s just a matter of burning the powders I have. I won’t change the barrel until it’s shot out. I’m a cheap sob.
