I recently pulled out a 7MM SuperMag barrel I had previously purchased and thought I would load some fodder to fling down range. My problem is that there seems to be little info on this cartridge. I have read where one can use 7MM TCU load data, but one of the loads I tried with a Sierra 120gr bullet was very compressed. I would like to hear from other 7MM SM loaders with their loads or at least some links to info on the web for this round. Thanks in advance for any help.
