I was wanting to know if anyone had loaded any of the nosler 150 gr hp 40s&w with unique powder. I bought the nosler manual but its like 5 years old and there is only 7 different powders they use and of course not unique. My sierra manual has 150 gr hp has unique listed. Would I be alright using there info for the powder I want to use? I am reloading for a glock 23 gen 4 and I do have the Lwd barrel. I have read that the gen 4 have to be more on the max side to function properly. I loaded some 180 gr sierra hp using unigue 6.0 grs which was .3 under the max and had a few failure to feed. some of my cases looked like they were maybe catching the lip on the top of the barrel and maybe the slide was catching the spent case and jamming it into the top lip. take a look at the pic. do i need to put the extra .1 or .2 grains in some more loads and see what happens or change powder. the next slower powder I have would be wsf. coal was at 1.125 +/- .001 The cases where new starline never fired. I've been reloading for a few years now but new to 40 s&w. so anyone with the nosler bullets 150 gr hp and hornady hp xtp 155 gr. using unique powder if you could pass on some useful information that would be great. Sorry for such a long post and all the questions. Thanks Wanna kill these ads? We can help!
