Re: Load Data
The GM3 load posted earlier refers to .357 loads used in a lever action rifle NOT.38 special.Lever357 wrote:Bought my reloading gear last week at the shooting show and the powder I got is Vectan GM3. This is not listed in my Lee handbook.
Was wondering if people had experience of it and what they would recommend for a 158gm bullet in .38 Special case. Chap I bought it off reckoned 3.8 grains of powder.
Do not use this data for .38 special

Re: Load Data
As UK rifleman states, the data given in that link is for .357 NOT .38 - otherwise I would not have started the post!!
