[QUOTE="Swamplord, post: 769700, member: 2460"] the 7.62 PRO was not intended to beat the 300 RUM in velocity but to equate the performance and have the ability to run high bc heavy bullets through 5 round AICS cip detachable mags... it turns out with the ability to seat the 200 + grn bullets way out to max fit the AICS mags , there is actually slightly more powder capacity with much better brass than the Rem 300 RUM. .. also with a shorter fatter case and a 35 degree shoulder and a much longer than usual neck for 30 cals. I am hoping to extend throat/barrel life accuracy over the 300 RUM with similar velocities in all bullet weights, in the event of extreme high bc 250 + gr bullets this case will excel even more over the 300 RUM without cartridge OAL limitations and having to run single shot........... it's all theory at this point and will have to be proven with a lot of loading and range time... rifle is completed and ready to go but no dies yet, still waiting !!!!!! my velocity goal is 3300 fps with 210 gr bullets in a 32" 5R 10 twist Rock Creek barrel give or take a few fps + or - ....
