All my manuals and the Internet tell me my brass for the 44 rem mag is to be 1.285 the longest new bras I have is 1.280 which i have loaded and seems to be fine. However i have some once fired factory loaded bras that i would like to use and most is around 1 .270. i want to load this with mag primers, 24 grains h110, and the hornady 240 gr. hp/xtp. this is the load i used in the 1.280 long brass. if I load the 1.270 long brass should i reduce the 24 gr of h110 ( 24 grains is the max load) to 23.5 grains. I am new to this reloading game and appreciate all the help I get from this site.
