Sherman Wildcat Reloading Data is Here!!!

Hey all. What barrel length and chamber freebore would I need to get a 160cx going 3000fps or more with the 7ss cartridge? Thanks!
Two 7 sheman max's, both 20", both showed about the same max velocity. 175 eld-x maxed out at around 2900ish with N565, that killed brass in 2-3 fireings. Accuracy and useable load around 2800. Add about 75-100 fps for a 160 mono vs the 175 eld-x, so 2875-2900. Add 20-30 fps/inch. Take away some for the ss vs the max. I would say at least a 24" with the ss to get to 3000, if you want your brass to last more than 3 rounds. 26" would be a safer bet.
