After a long time away I began playing with my two .41 Mags today.
The first one is a S&W M657 performance center 6 1/2" w/ a 4X Leupold shooting a 265gr. LBTL LWNGC over 20.8grs. of H110.
This load is smooth to shoot and accurate.
I have not shot them over my chronograph but my est velocity is about 1320 fps.
My other .41 is a Taurus total titanium 6 1/2" that is so light and accurate it is a joy to pack here in Western Wyoming.
My two favorite loads for this are as follows,
250gr, LBT WNFPGC over 18.5gr. of H110 gives me around 1200 fps. Then my other load is a 215 SWC over 17.3grs of 2400 which gives me right at 1250 fps.
The first two loads are what I plan to hunt with this year mainly with the 265 gr load should be plenty of punch from 100 yards and closer.
The Taurus has been my back up gun for several years and is accurate to shoot to 75 yards (with my eyes) with the 250gr.
Easier to shoot than my .44's with as much punch and flatter trajectory, what's not to love!
