I can handle a 425gr Hornady Great Plains and 100gr FFG Goex just fine. I have been shooting my dads 7mm since I was 10 or 11yrs old. I think the 7mm kicks a lot harder. I have never really been recoil sensative. A guy told me that you have to back your charge way down when shooing heavy conicals. I was just wanting to try some heavier loads but thought I would first ask if it is safe. I think 100gr FFG is perfect and I love that load but I would like to try some heavier charges just for the heck of it.
