I am tring to reload for my new 460 S&W mag. using acc.5744. I would like around 1600 fps out of a 250 xtp and 1400 fps out of a 300 xtp or lead bullet. I tried 36.0 gr. with the 250 xtp and only got 1330 fps and I tried 30.0 gr. with the 300 xtp and only got 1100 fps. I got these loads from several sources but they fell about 300 fps short of advertized fps. I am using 5744 because I really don't want full power loads.
I have some Cast Performance 300gr lead bullets coming and would like to get around 1400 fps out of them.
Is anyone using this acc. 5744 with these bullets at around this fps ?
I also like H110 but all of the manuals I have looked at have these two bullets at full power velocites with H110 and I am leery of reducing the loads too much with this powder.
