If anyone can help to ease my mind my next trip to the range will be more relaxing. I just got a chance to test my 12fv 22.250 handloads. While working my way up at 39.3grns of h380 I started to see bolt face marks on the case head. I would like to go up to 40.2 but am a little nervous. I have cases that I have once fired since factory trimmed to 1.902 and neck sized. I seated the bullet to 2.350 with fed 210 primers 55grn v-max. 39.3 has the best group but I would like to go higher just to be sure. Thanks
