41 rem mag 300grain gc loads

[whitetailsniper30tc]

hello all,    i have some load data for 41 rem mag ruger super blackhawk bisley hunter in 7 1/2 barrel,,but very little. the mold is from nei 300 grain gas ck. fn most of the data i have is using unique,w296,h110,and 2400. does anyone have any thing other than this data using other powder,and the amount of powder to use??  the data i have is giving me bullet creep,witch i cant seem to stop, i need to find other data for this mold to use on whitetail deer. my best accuracy load to date is using this bullet over 18 grains of w296@50 yrds grouping was exallant with stout recoil.but with bullet creep,and not able to stop it,it doesnt do me anygood. even tried a heavy crimp without buldging the case. so i need other data for this mold,if anyone can help its most greatful.   the more,the better.  please feel free to email me at  whitetailsniper@yahoo.com  thank you kindly.

Whew! That's a big bullet.  I don't think I have data for any that heavy but I'll check. I have done some loading of 250 gr jacketed and more with 250 to 265 cast using 4227 with decent results. I wonder if Lil Gun would work too?

I'll be watching this thread to see what other's suggest.
Have you checked the most recent Lee load book? They have a good range of load for the 41 mag but I don't know if they go up to 300 gr.

Have you considered a Lee Factory Crimp die for the 41 mag? That might crimp them hard enough but I hear it may also squeeze down the bullet more than is desired.
