Hi, C.hud what are you using for reloading data ? I bought some 62 gr. fmjbt 's from them awhile ago . I'm new to reloading & didn't think about data . I emailed them & he simply replied that he couldn't provide any info at this time. I've asked on other sites with answers all over the place from don't do it to start with minimuns . Some worries about jacket hardness & thickness. Any info would be great . Thanks , Jim
