I have a 300 super whisper OTT barrel that I am finally getting around to shooting have 200 rounds of brass made up and ready to go. I have no loading data. I want to shoot a 200gr bullet cast with my Egean (sp) mold. I was thinking of starting with 300 whisper data and working up. Just wondering if any of you load for the 300 Super Whisper and would be willing to share any info. Here or pm.
Thanks
Kirb
