vhit N320 for 357mag ?

[Devil_bri]

Finally got my Marlin 1894 38/357mag -- well chuffed !!!!

 

going to load 357 brass with a 38 load so need some advice

 

i am using Vhit 320 (as i have a lot of it for my 9mm pistol)

158gr lead TC from Hammans

after some research i am thinking 4gr of N320 up to 7gr

what do you guys think ? or if you have used N320, what loads are you happy with ?

i will be mainly plinking for the time being from 25 yards up to 50 yards

thanks

Brian
