Help --question on 297 powder

[GLynn41]

I was considering 297 surp powder for the following rounds -- wanted Lloyd or anyones experience or opinon -- it would be used in a .41 mag normally cast --41/44 in Revolver & 41/445 14" TC-- I read were Lloyd thought it was too slow for less than a .454-- if so I will pass

I'd treat it like it was 296. Magnum level loads and no reduced charges. If you're looking for something more mid-range level, pick another powder.

You must use Magnum primers for this powder. I tried standard pistol promers and the powder did on ignite properly/ Magnum Pistol Primers woeked OK.
